addroi

addroi(
    *,
    x: String = Default("0"),
    y: String = Default("0"),
    w: String = Default("0"),
    h: String = Default("0"),
    qoffset: Rational = Default("-1/10"),
    clear: Boolean = Default("false"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Mark a region of interest in a video frame.

The frame data is passed through unchanged, but metadata is attached to the frame indicating regions of interest which can affect the behaviour of later encoding. Multiple regions can be marked by applying the filter multiple times.

Parameters:

Name	Type	Description	Default
x	String	Region distance in pixels from the left edge of the frame.	Default('0')
y	String	Region distance in pixels from the top edge of the frame.	Default('0')
w	String	Region width in pixels.	Default('0')
h	String	Region height in pixels. The parameters x, y, w and h are expressions, and may contain the following variables: @end table	Default('0')
qoffset	Rational	Quantisation offset to apply within the region. This must be a real value in the range -1 to +1. A value of zero indicates no quality change. A negative value asks for better quality (less quantisation), while a positive value asks for worse quality (greater quantisation). The range is calibrated so that the extreme values indicate the largest possible offset - if the rest of the frame is encoded with the worst possible quality, an offset of -1 indicates that this region should be encoded with the best possible quality anyway. Intermediate values are then interpolated in some codec-dependent way. For example, in 10-bit H.264 the quantisation parameter varies between -12 and 51. A typical qoffset value of -1/10 therefore indicates that this region should be encoded with a QP around one-tenth of the full range better than the rest of the frame. So, if most of the frame were to be encoded with a QP of around 30, this region would get a QP of around 24 (an offset of approximately -1/10 * (51 - -12) = -6.3). An extreme value of -1 would indicate that this region should be encoded with the best possible quality regardless of the treatment of the rest of the frame - that is, should be encoded at a QP of -12.	Default('-1/10')
clear	Boolean	If set to true, remove any existing regions of interest marked on the frame before adding the new one.	Default('false')
extra_options	dict[str, Any] | None	Extra options for the filter	None

For example, to reconstruct full frames from a normal YUV-encoded video and a separate video created with alphaextract, you might use: @example movie=in_alpha.mkv [alpha]; [in][alpha] alphamerge [out] @end example

Parameters:

Name	Type	Description	Default

blackdetect

blackdetect(
    *,
    d: Double = Default("2"),
    picture_black_ratio_th: Double = Default("0.98"),
    pixel_black_th: Double = Default("0.1"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Detect video intervals that are (almost) completely black. Can be useful to detect chapter transitions, commercials, or invalid recordings.

The filter outputs its detection analysis to both the log as well as frame metadata. If a black segment of at least the specified minimum duration is found, a line with the start and end timestamps as well as duration is printed to the log with level info. In addition, a log line with level debug is printed per frame showing the black amount detected for that frame.

The filter also attaches metadata to the first frame of a black segment with key lavfi.black_start and to the first frame after the black segment ends with key lavfi.black_end. The value is the frame's timestamp. This metadata is added regardless of the minimum duration specified.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
d	Double	Set the minimum detected black duration expressed in seconds. It must be a non-negative floating point number. Default value is 2.0.	Default('2')
picture_black_ratio_th	Double	Set the threshold for considering a picture "black". Express the minimum value for the ratio: @example nb_black_pixels / nb_pixels @end example for which a picture is considered black. Default value is 0.98.	Default('0.98')
pixel_black_th	Double	Set the threshold for considering a pixel "black". The threshold expresses the maximum pixel luminance value for which a pixel is considered "black". The provided value is scaled according to the following equation: @example absolute_threshold = luminance_minimum_value + pixel_black_th * luminance_range_size @end example luminance_range_size and luminance_minimum_value depend on the input video format, the range is [0-255] for YUV full-range formats and [16-235] for YUV non full-range formats. Default value is 0.10.	Default('0.1')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

blackframe

blackframe(
    *,
    amount: Int = Default("98"),
    threshold: Int = Default("32"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Detect frames that are (almost) completely black. Can be useful to detect chapter transitions or commercials. Output lines consist of the frame number of the detected frame, the percentage of blackness, the position in the file if known or -1 and the timestamp in seconds.

In order to display the output lines, you need to set the loglevel at least to the AV_LOG_INFO value.

This filter exports frame metadata lavfi.blackframe.pblack. The value represents the percentage of pixels in the picture that are below the threshold value.

It accepts the following parameters:

Parameters:

Name	Type	Description	Default
amount	Int	The percentage of the pixels that have to be below the threshold; it defaults to 98.	Default('98')
threshold	Int	The threshold below which a pixel value is considered black; it defaults to 32.	Default('32')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Name	Type	Description
default	VideoStream	the video stream

) -> VideoStream

Blend two video frames into each other.

The blend filter takes two input streams and outputs one stream, the first input is the "top" layer and second input is "bottom" layer. By default, the output terminates when the longest input terminates.

The tblend (time blend) filter takes two consecutive frames from one single stream, and outputs the result obtained by blending the new frame on top of the old frame.

A description of the accepted options follows.

The high threshold selects the "strong" edge pixels, which are then connected through 8-connectivity with the "weak" edge pixels selected by the low threshold. low and high threshold values must be chosen in the range [0,1], and low should be lesser or equal to high. Default value for low is 20/255, and default value for high is 50/255.	Default('0.117647')
low	Float	set low threshold (from 0 to 1) (default 0.0588235)	Default('0.0588235')
radius	Int	Define the radius to search around an edge pixel for local maxima.	Default('50')
block_pct	Int	Determine blurriness only for the most significant blocks, given in percentage.	Default('80')
block_width	Int	Determine blurriness for blocks of width block_width. If set to any value smaller 1, no blocks are used and the whole image is processed as one no matter of block_height.	Default('-1')
planes	Int	Set planes to filter. Default is first only.	Default('1')
extra_options	dict[str, Any] | None	Extra options for the filter	None

RGB colorspace color keying. This filter operates on 8-bit RGB format frames by setting the alpha component of each pixel which falls within the similarity radius of the key color to 0. The alpha value for pixels outside the similarity radius depends on the value of the blend option.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
color	Color	Set the color for which alpha will be set to 0 (full transparency). See "Color" section in the ffmpeg-utils manual. Default is black.	Default('black')
similarity	Float	Set the radius from the key color within which other colors also have full transparency. The computed distance is related to the unit fractional distance in 3D space between the RGB values of the key color and the pixel's color. Range is 0.01 to 1.0. 0.01 matches within a very small radius around the exact key color, while 1.0 matches everything. Default is 0.01.	Default('0.01')
blend	Float	Set how the alpha value for pixels that fall outside the similarity radius is computed. 0.0 makes pixels either fully transparent or fully opaque. Higher values result in semi-transparent pixels, with greater transparency the more similar the pixel color is to the key color. Range is 0.0 to 1.0. Default is 0.0.	Default('0')
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

) -> VideoStream

Auto-detect the crop size.

It calculates the necessary cropping parameters and prints the recommended parameters via the logging system. The detected dimensions correspond to the non-black area of the input video.

It accepts the following parameters:

Parameters:

Name	Type	Description	Default
limit	Float	Set higher black value threshold, which can be optionally specified from nothing (0) to everything (255 for 8-bit based formats). An intensity value greater to the set value is considered non-black. It defaults to 24. You can also specify a value between 0.0 and 1.0 which will be scaled depending on the bitdepth of the pixel format.	Default('0.0941176')
round	Int	The value which the width/height should be divisible by. It defaults to 16. The offset is automatically adjusted to center the video. Use 2 to get only even dimensions (needed for 4:2:2 video). 16 is best when encoding to most video codecs.	Default('16')
reset	Int	Set the counter that determines after how many frames cropdetect will reset the previously detected largest video area and start over to detect the current optimal crop area. Default value is 0. This can be useful when channel logos distort the video area. 0 indicates 'never reset', and returns the largest area encountered during playback.	Default('0')
skip	Int	Set the number of initial frames for which evaluation is skipped. Default is 2. Range is 0 to INT_MAX.	Default('2')
reset_count	Int	Set the counter that determines after how many frames cropdetect will reset the previously detected largest video area and start over to detect the current optimal crop area. Default value is 0. This can be useful when channel logos distort the video area. 0 indicates 'never reset', and returns the largest area encountered during playback.	Default('0')
max_outliers	Int	Threshold count of outliers (from 0 to INT_MAX) (default 0)	Default('0')

cue

cue(
    *,
    cue: Int64 = Default("0"),
    preroll: Duration = Default("0"),
    buffer: Duration = Default("0"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Delay video filtering until a given wallclock timestamp. The filter first passes on preroll amount of frames, then it buffers at most buffer amount of frames and waits for the cue. After reaching the cue it forwards the buffered frames and also any subsequent frames coming in its input.

The filter can be used synchronize the output of multiple ffmpeg processes for realtime output devices like decklink. By putting the delay in the filtering chain and pre-buffering frames the process can pass on data to output almost immediately after the target wallclock timestamp is reached.

Perfect frame accuracy cannot be guaranteed, but the result is good enough for some use cases.

Parameters:

Name	Type	Description	Default
cue	Int64	The cue timestamp expressed in a UNIX timestamp in microseconds. Default is 0.	Default('0')
preroll	Duration	The duration of content to pass on as preroll expressed in seconds. Default is 0.	Default('0')
buffer	Duration	The maximum duration of content to buffer before waiting for the cue expressed in seconds. Default is 0.	Default('0')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

) -> VideoStream

Apply color adjustments using curves.

This filter is similar to the Adobe Photoshop and GIMP curves tools. Each component (red, green and blue) has its values defined by N key points tied from each other using a smooth curve. The x-axis represents the pixel values from the input frame, and the y-axis the new pixel values to be set for the output frame.

By default, a component curve is defined by the two points (0;0) and (1;1). This creates a straight line where each original pixel value is "adjusted" to its own value, which means no change to the image.

The filter allows you to redefine these two points and add some more. A new curve (using a natural cubic spline interpolation) will be define to pass smoothly through all these new coordinates. The new defined points needs to be strictly increasing over the x-axis, and their x and y values must be in the [0;1] interval. If the computed curves happened to go outside the vector spaces, the values will be clipped accordingly.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
preset	Int | Literal['none', 'color_negative', 'cross_process', 'darker', 'increase_contrast', 'lighter', 'linear_contrast', 'medium_contrast', 'negative', 'strong_contrast', 'vintage'] | Default	Select one of the available color presets. This option can be used in addition to the r, g, b parameters; in this case, the later options takes priority on the preset values. Available presets are: @end table Default is none.	Default('none')
master	String	Set the master key points. These points will define a second pass mapping. It is sometimes called a "luminance" or "value" mapping. It can be used with r, g, b or all since it acts like a post-processing LUT.	Default(None)
red	String	Set the key points for the red component.	Default(None)
green	String	Set the key points for the green component.	Default(None)
blue	String	Set the key points for the blue component.	Default(None)
all	String	Set the key points for all components (not including master). Can be used in addition to the other key points component options. In this case, the unset component(s) will fallback on this all setting.	Default(None)
psfile	String	Specify a Photoshop curves file (.acv) to import the settings from.	Default(None)
plot	String	Save Gnuplot script of the curves in specified file.	Default(None)
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

    enable: str | None = None,
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Denoise frames using 2D DCT (frequency domain filtering).

This filter is not designed for real time.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
sigma	Float	Set the noise sigma constant. This sigma defines a hard threshold of 3 * sigma; every DCT coefficient (absolute value) below this threshold with be dropped. If you need a more advanced filtering, see expr. Default is 0.	Default('0')
overlap	Int	Set number overlapping pixels for each block. Since the filter can be slow, you may want to reduce this value, at the cost of a less effective filter and the risk of various artefacts. If the overlapping value doesn't permit processing the whole input width or height, a warning will be displayed and according borders won't be denoised. Default value is blocksize-1, which is the best possible setting.	Default('-1')
expr	String	Set the coefficient factor expression. For each coefficient of a DCT block, this expression will be evaluated as a multiplier value for the coefficient. If this is option is set, the sigma option will be ignored. The absolute value of the coefficient can be accessed through the c variable.	Default(None)
n	Int	Set the blocksize using the number of bits. 1<<n defines the blocksize, which is the width and height of the processed blocks. The default value is 3 (8x8) and can be raised to 4 for a blocksize of 16x16. Note that changing this setting has huge consequences on the speed processing. Also, a larger block size does not necessarily means a better de-noising.	Default('3')

_4thr	Float	Set banding detection threshold for each plane. Default is 0.02. Valid range is 0.00003 to 0.5. If difference between current pixel and reference pixel is less than threshold, it will be considered as banded.	Default('0.02')
range	Int	Banding detection range in pixels. Default is 16. If positive, random number in range 0 to set value will be used. If negative, exact absolute value will be used. The range defines square of four pixels around current pixel.	Default('16')
direction	Float	Set direction in radians from which four pixel will be compared. If positive, random direction from 0 to set direction will be picked. If negative, exact of absolute value will be picked. For example direction 0, -PI or -2*PI radians will pick only pixels on same row and -PI/2 will pick only pixels on same column.	Default('6.28319')
blur	Boolean	If enabled, current pixel is compared with average value of all four surrounding pixels. The default is enabled. If disabled current pixel is compared with all four surrounding pixels. The pixel is considered banded if only all four differences with surrounding pixels are less than threshold.	Default('true')
coupling	Boolean	If enabled, current pixel is changed if and only if all pixel components are banded, e.g. banding detection threshold is triggered for all color components. The default is disabled.	Default('false')

Attempt to fix small changes in horizontal and/or vertical shift. This filter helps remove camera shake from hand-holding a camera, bumping a tripod, moving on a vehicle, etc.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
x	Int	set x for the rectangular search area (from -1 to INT_MAX) (default -1)	Default('-1')
y	Int	set y for the rectangular search area (from -1 to INT_MAX) (default -1)	Default('-1')
w	Int	set width for the rectangular search area (from -1 to INT_MAX) (default -1)	Default('-1')
h	Int	Specify a rectangular area where to limit the search for motion vectors. If desired the search for motion vectors can be limited to a rectangular area of the frame defined by its top left corner, width and height. These parameters have the same meaning as the drawbox filter which can be used to visualise the position of the bounding box. This is useful when simultaneous movement of subjects within the frame might be confused for camera motion by the motion vector search. If any or all of x, y, w and h are set to -1 then the full frame is used. This allows later options to be set without specifying the bounding box for the motion vector search. Default - search the whole frame.	Default('-1')
rx	Int	set x for the rectangular search area (from 0 to 64) (default 16)	Default('16')
ry	Int	Specify the maximum extent of movement in x and y directions in the range 0-64 pixels. Default 16.	Default('16')
edge	Int | Literal['blank', 'original', 'clamp', 'mirror'] | Default	Specify how to generate pixels to fill blanks at the edge of the frame. Available values are: @end table Default value is mirror.	Default('mirror')
blocksize	Int	Specify the blocksize to use for motion search. Range 4-128 pixels, default 8.	Default('8')
contrast	Int	Specify the contrast threshold for blocks. Only blocks with more than the specified contrast (difference between darkest and lightest pixels) will be considered. Range 1-255, default 125.	Default('125')
search	Int | Literal['exhaustive', 'less'] | Default	Specify the search strategy. Available values are: @end table Default value is exhaustive.	Default('exhaustive')
filename	String	If set then a detailed log of the motion search is written to the specified file.	Default(None)
opencl	Boolean	ignored (default false)	Default('false')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Displace pixels as indicated by second and third input stream.

It takes three input streams and outputs one stream, the first input is the source, and second and third input are displacement maps.

The second input specifies how much to displace pixels along the x-axis, while the third input specifies how much to displace pixels along the y-axis. If one of displacement map streams terminates, last frame from that displacement map will be used.

Note that once generated, displacements maps can be reused over and over again.

A description of the accepted options follows.

Parameters:

Name	Type	Description	Default
edge	Int | Literal['blank', 'smear', 'wrap', 'mirror'] | Default	Set displace behavior for pixels that are out of range. Available values are: @end table Default is smear.	Default('smear')

y	String	The x and y offset coordinates where the box is drawn.	Default('0')
width	String	set width of the box (default "0")	Default('0')
height	String	The expressions which specify the width and height of the box; if 0 they are interpreted as the input width and height. It defaults to 0.	Default('0')
color	String	Specify the color of the box to write. For the general syntax of this option, check the "Color" section in the ffmpeg-utils manual. If the special value invert is used, the box edge color is the same as the video with inverted luma.	Default('black')
thickness	String	The expression which sets the thickness of the box edge. A value of fill will create a filled box. Default value is 3. See below for the list of accepted constants.	Default('3')
replace	Boolean	Applicable if the input has alpha. With value 1, the pixels of the painted box will overwrite the video's color and alpha pixels. Default is 0, which composites the box onto the input, leaving the video's alpha intact.	Default('false')
box_source	String	Box source can be set as side_data_detection_bboxes if you want to use box data in detection bboxes of side data. If box_source is set, the x, y, width and height will be ignored and still use box data in detection bboxes of side data.

Apply feedback video filter.

This filter pass cropped input frames to 2nd output. From there it can be filtered with other video filters. After filter receives frame from 2nd input, that frame is combined on top of original frame from 1st input and passed to 1st output.

The typical usage is filter only part of frame.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
x	Int	set top left crop position (from 0 to INT_MAX) (default 0)	Default('0')
w	Int	set crop size (from 0 to INT_MAX) (default 0)	Default('0')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Name	Type	Description
default	VideoStream	the video stream
feedout	VideoStream	the video stream

Change the frame rate by interpolating new video output frames from the source frames.

This filter is not designed to function correctly with interlaced media. If you wish to change the frame rate of interlaced media then you are required to deinterlace before this filter and re-interlace after this filter.

A description of the accepted options follows.

Parameters:

Name	Type	Description	Default
fps	Video_rate	Specify the output frames per second. This option can also be specified as a value alone. The default is 50.	Default('50')
interp_start	Int	Specify the start of a range where the output frame will be created as a linear interpolation of two frames. The range is [0-255], the default is 15.	Default('15')
interp_end	Int	Specify the end of a range where the output frame will be created as a linear interpolation of two frames. The range is [0-255], the default is 240.	Default('240')
scene	Double	Specify the level at which a scene change is detected as a value between 0 and 100 to indicate a new scene; a low value reflects a low probability for the current frame to introduce a new scene, while a higher value means the current frame is more likely to be one. The default is 8.2.	Default('8.2')
flags	Flags | Literal['scene_change_detect', 'scd'] | Default	Specify flags influencing the filter process. Available value for flags is: @end table	Default('scene_change_detect+scd')

    extra_options: dict[str, Any] | None = None
) -> VideoStream

Detect frozen video.

This filter logs a message and sets frame metadata when it detects that the input video has no significant change in content during a specified duration. Video freeze detection calculates the mean average absolute difference of all the components of video frames and compares it to a noise floor.

The printed times and duration are expressed in seconds. The lavfi.freezedetect.freeze_start metadata key is set on the first frame whose timestamp equals or exceeds the detection duration and it contains the timestamp of the first frame of the freeze. The lavfi.freezedetect.freeze_duration and lavfi.freezedetect.freeze_end metadata keys are set on the first frame after the freeze.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
n	Double	Set noise tolerance. Can be specified in dB (in case "dB" is appended to the specified value) or as a difference ratio between 0 and 1. Default is -60dB, or 0.001.	Default('0.001')
d	Duration	Set freeze duration until notification (default is 2 seconds).	Default('2')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Apply fast and simple postprocessing. It is a faster version of spp.

It splits (I)DCT into horizontal/vertical passes. Unlike the simple post- processing filter, one of them is performed once per block, not per pixel. This allows for much higher speed.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
quality	Int	Set quality. This option defines the number of levels for averaging. It accepts an integer in the range 4-5. Default value is 4.	Default('4')
qp	Int	Force a constant quantization parameter. It accepts an integer in range 0-63. If not set, the filter will use the QP from the video stream (if available).	Default('0')
strength	Int	Set filter strength. It accepts an integer in range -15 to 32. Lower values mean more details but also more artifacts, while higher values make the image smoother but also blurrier. Default value is 0 − PSNR optimal.	Default('0')
use_bframe_qp	Boolean	Enable the use of the QP from the B-Frames if set to 1. Using this option may cause flicker since the B-Frames have often larger QP. Default is 0 (not enabled).	Default('false')
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Fix the banding artifacts that are sometimes introduced into nearly flat regions by truncation to 8-bit color depth. Interpolate the gradients that should go where the bands are, and dither them.

It is designed for playback only. Do not use it prior to lossy compression, because compression tends to lose the dither and bring back the bands.

It accepts the following parameters:

Parameters:

Name	Type	Description	Default
strength	Float	The maximum amount by which the filter will change any one pixel. This is also the threshold for detecting nearly flat regions. Acceptable values range from .51 to 64; the default value is 1.2. Out-of-range values will be clipped to the valid range.	Default('1.2')
radius	Int	The neighborhood to fit the gradient to. A larger radius makes for smoother gradients, but also prevents the filter from modifying the pixels near detailed regions. Acceptable values are 8-32; the default value is 16. Out-of-range values will be clipped to the valid range.	Default('16')
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

) -> VideoStream

This filter applies a global color histogram equalization on a per-frame basis.

It can be used to correct video that has a compressed range of pixel intensities. The filter redistributes the pixel intensities to equalize their distribution across the intensity range. It may be viewed as an "automatically adjusting contrast filter". This filter is useful only for correcting degraded or poorly captured source video.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
strength	Float	Determine the amount of equalization to be applied. As the strength is reduced, the distribution of pixel intensities more-and-more approaches that of the input frame. The value must be a float number in the range [0,1] and defaults to 0.200.	Default('0.2')
intensity	Float	Set the maximum intensity that can generated and scale the output values appropriately. The strength should be set as desired and then the intensity can be limited if needed to avoid washing-out. The value must be a float number in the range [0,1] and defaults to 0.210.	Default('0.21')
antibanding	Int | Literal['none', 'weak', 'strong'] | Default	Set the antibanding level. If enabled the filter will randomly vary the luminance of output pixels by a small amount to avoid banding of the histogram. Possible values are none, weak or strong. It defaults to none.	Default('none')
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

    reverse: Int = Default("0"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Map hardware frames to system memory or to another device.

This filter has several different modes of operation; which one is used depends on the input and output formats:

Parameters:

Name	Type	Description	Default
mode	Flags | Literal['read', 'write', 'overwrite', 'direct'] | Default	Set the frame mapping mode. Some combination of: @end table Defaults to read+write if not specified.	Default('read+write')
derive_device	String	Derive a new device of this type	Default(None)
reverse	Int	In a hardware to hardware mapping, map in reverse - create frames in the sink and map them back to the source. This may be necessary in some cases where a mapping in one direction is required but only the opposite direction is supported by the devices being used. This option is dangerous - it may break the preceding filter in undefined ways if there are any additional constraints on that filter's output. Do not use it without fully understanding the implications of its use.	Default('0')

    extra_options: dict[str, Any] | None = None
) -> VideoStream

Upload system memory frames to hardware surfaces.

The device to upload to must be supplied when the filter is initialised. If using ffmpeg, select the appropriate device with the -filter_hw_device option or with the derive_device option. The input and output devices must be of different types and compatible - the exact meaning of this is system-dependent, but typically it means that they must refer to the same underlying hardware context (for example, refer to the same graphics card).

The following additional parameters are accepted:

Parameters:

Name	Type	Description	Default

) -> VideoStream

Obtain the identity score between two input videos.

This filter takes two input videos.

Both input videos must have the same resolution and pixel format for this filter to work correctly. Also it assumes that both inputs have the same number of frames, which are compared one by one.

The obtained per component, average, min and max identity score is printed through the logging system.

The filter stores the calculated identity scores of each frame in frame metadata.

In the below example the input file main.mpg being processed is compared with the reference file ref.mpg.

@example ffmpeg -i main.mpg -i ref.mpg -lavfi identity -f null - @end example

Parameters:

Name	Type	Description	Default
framesync_options	FFMpegFrameSyncOption | None	Framesync options	None
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

    half_life: Float = Default("0"),
    analyze_interlaced_flag: Int = Default("0"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Detect video interlacing type.

This filter tries to detect if the input frames are interlaced, progressive, top or bottom field first. It will also try to detect fields that are repeated between adjacent frames (a sign of telecine).

Single frame detection considers only immediately adjacent frames when classifying each frame. Multiple frame detection incorporates the classification history of previous frames.

The filter will log these metadata values:

Parameters:

Name	Type	Description	Default
intl_thres	Float	Set interlacing threshold.	Default('1.04')
prog_thres	Float	Set progressive threshold.	Default('1.5')
rep_thres	Float	Threshold for repeated field detection.	Default('3')
half_life	Float	Number of frames after which a given frame's contribution to the statistics is halved (i.e., it contributes only 0.5 to its classification). The default of 0 means that all frames seen are given full weight of 1.0 forever.	Default('0')
analyze_interlaced_flag	Int	When this is not 0 then idet will use the specified number of frames to determine if the interlaced flag is accurate, it will not count undetermined frames. If the flag is found to be accurate it will be used without any further computations, if it is found to be inaccurate it will be cleared without any further computations. This allows inserting the idet filter as a low computational method to clean up the interlaced flag	Default('0')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Deinterleave or interleave fields.

This filter allows one to process interlaced images fields without deinterlacing them. Deinterleaving splits the input frame into 2 fields (so called half pictures). Odd lines are moved to the top half of the output image, even lines to the bottom half. You can process (filter) them independently and then re-interleave them.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
luma_mode	Int | Literal['none', 'interleave', 'i', 'deinterleave', 'd'] | Default	select luma mode (from 0 to 2) (default none)	Default('none')

Correct radial lens distortion

This filter can be used to correct for radial distortion as can result from the use of wide angle lenses, and thereby re-rectify the image. To find the right parameters one can use tools available for example as part of opencv or simply trial-and-error. To use opencv use the calibration sample (under samples/cpp) from the opencv sources and extract the k1 and k2 coefficients from the resulting matrix.

Note that effectively the same filter is available in the open-source tools Krita and Digikam from the KDE project.

In contrast to the vignette filter, which can also be used to compensate lens errors, this filter corrects the distortion of the image, whereas vignette corrects the brightness distribution, so you may want to use both filters together in certain cases, though you will have to take care of ordering, i.e. whether vignetting should be applied before or after lens correction.

Parameters:

Name	Type	Description	Default
cx	Double	Relative x-coordinate of the focal point of the image, and thereby the center of the distortion. This value has a range [0,1] and is expressed as fractions of the image width. Default is 0.5.	Default('0.5')
cy	Double	Relative y-coordinate of the focal point of the image, and thereby the center of the distortion. This value has a range [0,1] and is expressed as fractions of the image height. Default is 0.5.	Default('0.5')
k1	Double	Coefficient of the quadratic correction term. This value has a range [-1,1]. 0 means no correction. Default is 0.	Default('0')
k2	Double	Coefficient of the double quadratic correction term. This value has a range [-1,1]. 0 means no correction. Default is 0.	Default('0')
i	Int | Literal['nearest', 'bilinear'] | Default	Set interpolation type. Can be nearest or bilinear. Default is nearest.	Default('nearest')
fc	Color	Specify the color of the unmapped pixels. For the syntax of this option, check the "Color" section in the ffmpeg-utils manual. Default color is black@0.	Default('black@0')
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

    frac: Float = Default("0.33"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Drop frames that do not differ greatly from the previous frame in order to reduce frame rate.

The main use of this filter is for very-low-bitrate encoding (e.g. streaming over dialup modem), but it could in theory be used for fixing movies that were inverse-telecined incorrectly.

A description of the accepted options follows.

Parameters:

Name	Type	Description	Default
max	Int	Set the maximum number of consecutive frames which can be dropped (if positive), or the minimum interval between dropped frames (if negative). If the value is 0, the frame is dropped disregarding the number of previous sequentially dropped frames. Default value is 0.	Default('0')
hi	Int	set high dropping threshold (from INT_MIN to INT_MAX) (default 768)	Default('768')
lo	Int	set low dropping threshold (from INT_MIN to INT_MAX) (default 320)	Default('320')
frac	Float	Set the dropping threshold values. Values for hi and lo are for 8x8 pixel blocks and represent actual pixel value differences, so a threshold of 64 corresponds to 1 unit of difference for each pixel, or the same spread out differently over the block. A frame is a candidate for dropping if no 8x8 blocks differ by more than a threshold of hi, and if no more than frac blocks (1 meaning the whole image) differ by more than a threshold of lo. Default value for hi is 6412, default value for lo is 645, and default value for frac is 0.33.	Default('0.33')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

) -> VideoStream

Obtain the MSAD (Mean Sum of Absolute Differences) between two input videos.

This filter takes two input videos.

Both input videos must have the same resolution and pixel format for this filter to work correctly. Also it assumes that both inputs have the same number of frames, which are compared one by one.

The obtained per component, average, min and max MSAD is printed through the logging system.

The filter stores the calculated MSAD of each frame in frame metadata.

In the below example the input file main.mpg being processed is compared with the reference file ref.mpg.

@example ffmpeg -i main.mpg -i ref.mpg -lavfi msad -f null - @end example

Parameters:

Name	Type	Description	Default
framesync_options	FFMpegFrameSyncOption | None	Framesync options	None
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Denoise frames using Non-Local Means algorithm.

Each pixel is adjusted by looking for other pixels with similar contexts. This context similarity is defined by comparing their surrounding patches of size pxp. Patches are searched in an area of rxr around the pixel.

Note that the research area defines centers for patches, which means some patches will be made of pixels outside that research area.

The filter accepts the following options.

Parameters:

Name	Type	Description	Default
s	Double	Set denoising strength. Default is 1.0. Must be in range [1.0, 30.0].	Default('1')
p	Int	Set patch size. Default is 7. Must be odd number in range [0, 99].	Default('7')
pc	Int	Same as p but for chroma planes. The default value is 0 and means automatic.	Default('0')
r	Int	Set research size. Default is 15. Must be odd number in range [0, 99].	Default('15')
rc	Int	Same as r but for chroma planes. The default value is 0 and means automatic.	Default('0')
timeline_options	FFMpegTimelineOption | None	Timeline options	None

etype	Int | Literal['a', 'abs', 's', 'mse'] | Default	Set which set of weights to use in the predictor. Can be one of the following: @end table	Default('a')
pscrn	Int | Literal['none', 'original', 'new', 'new2', 'new3'] | Default	Controls whether or not the prescreener neural network is used to decide which pixels should be processed by the predictor neural network and which can be handled by simple cubic interpolation. The prescreener is trained to know whether cubic interpolation will be sufficient for a pixel or whether it should be predicted by the predictor nn. The computational complexity of the prescreener nn is much less than that of the predictor nn. Since most pixels can be handled by cubic interpolation, using the prescreener generally results in much faster processing. The prescreener is pretty accurate, so the difference between using it and not using it is almost always unnoticeable. Can be one of the following: @end table Default is new.	Default('new')

normalize

normalize(
    *,
    blackpt: Color = Default("black"),
    whitept: Color = Default("white"),
    smoothing: Int = Default("0"),
    independence: Float = Default("1"),
    strength: Float = Default("1"),

    extra_options: dict[str, Any] | None = None
) -> VideoStream

Normalize RGB video (aka histogram stretching, contrast stretching). See: https://en.wikipedia.org/wiki/Normalization_(image_processing)

For each channel of each frame, the filter computes the input range and maps it linearly to the user-specified output range. The output range defaults to the full dynamic range from pure black to pure white.

Temporal smoothing can be used on the input range to reduce flickering (rapid changes in brightness) caused when small dark or bright objects enter or leave the scene. This is similar to the auto-exposure (automatic gain control) on a video camera, and, like a video camera, it may cause a period of over- or under-exposure of the video.

The R,G,B channels can be normalized independently, which may cause some color shifting, or linked together as a single channel, which prevents color shifting. Linked normalization preserves hue. Independent normalization does not, so it can be used to remove some color casts. Independent and linked normalization can be combined in any ratio.

The normalize filter accepts the following options:

Parameters:

Name	Type	Description	Default
blackpt	Color	output color to which darkest input color is mapped (default "black")	Default('black')
whitept	Color	Colors which define the output range. The minimum input value is mapped to the blackpt. The maximum input value is mapped to the whitept. The defaults are black and white respectively. Specifying white for blackpt and black for whitept will give color-inverted, normalized video. Shades of grey can be used to reduce the dynamic range (contrast). Specifying saturated colors here can create some interesting effects.	Default('white')
smoothing	Int	The number of previous frames to use for temporal smoothing. The input range of each channel is smoothed using a rolling average over the current frame and the smoothing previous frames. The default is 0 (no temporal smoothing).	Default('0')
independence	Float	Controls the ratio of independent (color shifting) channel normalization to linked (color preserving) normalization. 0.0 is fully linked, 1.0 is fully independent. Defaults to 1.0 (fully independent).	Default('1')
strength	Float	Overall strength of the filter. 1.0 is full strength. 0.0 is a rather expensive no-op. Defaults to 1.0 (full strength).	Default('1')
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

default	VideoStream	the video stream

Use a palette to downsample an input video stream.

The filter takes two inputs: one video stream and a palette. The palette must be a 256 pixels image.

It accepts the following options:

Parameters:

Name	Type	Description	Default
dither	Int | Literal['bayer', 'heckbert', 'floyd_steinberg', 'sierra2', 'sierra2_4a'] | Default	Select dithering mode. Available algorithms are: @end table Default is sierra2_4a.	Default('sierra2_4a')
bayer_scale	Int	When bayer dithering is selected, this option defines the scale of the pattern (how much the crosshatch pattern is visible). A low value means more visible pattern for less banding, and higher value means less visible pattern at the cost of more banding. The option must be an integer value in the range [0,5]. Default is 2.	Default('2')
diff_mode	Int | Literal['rectangle'] | Default	If set, define the zone to process @end table Default is none.	Default('0')
new	Boolean	Take new palette for each output frame.	Default('false')
alpha_threshold	Int	Sets the alpha threshold for transparency. Alpha values above this threshold will be treated as completely opaque, and values below this threshold will be treated as completely transparent. The option must be an integer value in the range [0,255]. Default is 128.	Default('128')
use_alpha	Boolean	Apply the palette by taking alpha values into account. Only useful with palettes that are containing multiple colors with alpha components. Setting this will automatically disable 'alpha_treshold'.	Default('false')
debug_kdtree	String	save Graphviz graph of the kdtree in specified file	Default(None)
color_search	Int | Literal['nns_iterative', 'nns_recursive', 'bruteforce'] | Default	set reverse colormap color search method (from 0 to 2) (default nns_iterative)	Default('nns_iterative')
mean_err	Boolean	compute and print mean error (default false)	Default('false')
debug_accuracy	Boolean	test color search accuracy (default false)	Default('false')

) -> VideoStream

Obtain the average, maximum and minimum PSNR (Peak Signal to Noise Ratio) between two input videos.

This filter takes in input two input videos, the first input is considered the "main" source and is passed unchanged to the output. The second input is used as a "reference" video for computing the PSNR.

Both video inputs must have the same resolution and pixel format for this filter to work correctly. Also it assumes that both inputs have the same number of frames, which are compared one by one.

The obtained average PSNR is printed through the logging system.

The filter stores the accumulated MSE (mean squared error) of each frame, and at the end of the processing it is averaged across all frames equally, and the following formula is applied to obtain the PSNR:

@example PSNR = 10*log10(MAX^2/MSE) @end example

Where MAX is the average of the maximum values of each component of the image.

The description of the accepted parameters follows.

Parameters:

Name	Type	Description	Default
stats_file	String	If specified the filter will use the named file to save the PSNR of each individual frame. When filename equals "-" the data is sent to standard output.	Default(None)
stats_version	Int	Specifies which version of the stats file format to use. Details of each format are written below. Default value is 1.	Default('1')
output_max	Boolean	Add raw stats (max values) to the output log. (default false)	Default('false')
framesync_options	FFMpegFrameSyncOption | None	Framesync options	None
timeline_options	FFMpegTimelineOption | None	Timeline options	None

pullup

pullup(

        "y"
    ),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Pulldown reversal (inverse telecine) filter, capable of handling mixed hard-telecine, 24000/1001 fps progressive, and 30000/1001 fps progressive content.

The pullup filter is designed to take advantage of future context in making its decisions. This filter is stateless in the sense that it does not lock onto a pattern to follow, but it instead looks forward to the following fields in order to identify matches and rebuild progressive frames.

To produce content with an even framerate, insert the fps filter after pullup, use fps=24000/1001 if the input frame rate is 29.97fps, fps=24 for 30fps and the (rare) telecined 25fps input.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
jl	Int	set left junk size (from 0 to INT_MAX) (default 1)	Default('1')
jr	Int	set right junk size (from 0 to INT_MAX) (default 1)	Default('1')
jt	Int	set top junk size (from 1 to INT_MAX) (default 4)	Default('4')
jb	Int	These options set the amount of "junk" to ignore at the left, right, top, and bottom of the image, respectively. Left and right are in units of 8 pixels, while top and bottom are in units of 2 lines. The default is 8 pixels on each side.	Default('4')
sb	Boolean	Set the strict breaks. Setting this option to 1 will reduce the chances of filter generating an occasional mismatched frame, but it may also cause an excessive number of frames to be dropped during high motion sequences. Conversely, setting it to -1 will make filter match fields more easily. This may help processing of video where there is slight blurring between the fields, but may also cause there to be interlaced frames in the output. Default value is 0.	Default('false')
mp	Int | Literal['y', 'u', 'v'] | Default	Set the metric plane to use. It accepts the following values: @end table This option may be set to use chroma plane instead of the default luma plane for doing filter's computations. This may improve accuracy on very clean source material, but more likely will decrease accuracy, especially if there is chroma noise (rainbow effect) or any grayscale video. The main purpose of setting mp to a chroma plane is to reduce CPU load and make pullup usable in realtime on slow machines.	Default('y')

realtime

realtime(
    *,
    limit: Duration = Default("2"),
    speed: Double = Default("1"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Slow down filtering to match real time approximately.

These filters will pause the filtering for a variable amount of time to match the output rate with the input timestamps. They are similar to the re option to ffmpeg.

They accept the following options:

Parameters:

Name	Type	Description	Default
limit	Duration	Time limit for the pauses. Any pause longer than that will be considered a timestamp discontinuity and reset the timer. Default is 2 seconds.	Default('2')
speed	Double	Speed factor for processing. The value must be a float larger than zero. Values larger than 1.0 will result in faster than realtime processing, smaller will slow processing down. The limit is automatically adapted accordingly. Default is 1.0. A processing speed faster than what is possible without these filters cannot be achieved.	Default('1')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

    fill: Color = Default("black"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Remap pixels using 2nd: Xmap and 3rd: Ymap input video stream.

Destination pixel at position (X, Y) will be picked from source (x, y) position where x = Xmap(X, Y) and y = Ymap(X, Y). If mapping values are out of range, zero value for pixel will be used for destination pixel.

Xmap and Ymap input video streams must be of same dimensions. Output video stream will have Xmap/Ymap video stream dimensions. Xmap and Ymap input video streams are 16bit depth, single channel.

Parameters:

Name	Type	Description	Default
format	Int | Literal['color', 'gray'] | Default	Specify pixel format of output from this filter. Can be color or gray. Default is color.	Default('color')
fill	Color	Specify the color of the unmapped pixels. For the syntax of this option, check the "Color" section in the ffmpeg-utils manual. Default color is black.	Default('black')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Scale (resize) the input video, using the libswscale library.

The scale filter forces the output display aspect ratio to be the same of the input, by changing the output sample aspect ratio.

If the input image format is different from the format requested by the next filter, the scale filter will convert the input to the requested format.

Parameters:

Name	Type	Description	Default
w	String	Output video width	Default(None)
h	String	Set the output video dimension expression. The command accepts the same syntax of the corresponding option. If the specified expression is not valid, it is kept at its current value.	Default(None)
flags	String	Set libswscale scaling flags. See the ffmpeg-scaler manual for the complete list of values. If not explicitly specified the filter applies the default flags.	Default('')
interl	Boolean	Set the interlacing mode. It accepts the following values: @end table Default value is 0.	Default('false')
in_color_matrix	String | Literal['auto', 'bt601', 'bt470', 'smpte170m', 'bt709', 'fcc', 'smpte240m', 'bt2020'] | Default	set input YCbCr type (default "auto")	Default('auto')
out_color_matrix	String | Literal['auto', 'bt601', 'bt470', 'smpte170m', 'bt709', 'fcc', 'smpte240m', 'bt2020'] | Default	Set in/output YCbCr color space type. This allows the autodetected value to be overridden as well as allows forcing a specific value used for the output and encoder. If not specified, the color space type depends on the pixel format. Possible values: @end table	Default(None)
in_range	Int | Literal['auto', 'unknown', 'full', 'limited', 'jpeg', 'mpeg', 'tv', 'pc'] | Default	set input color range (from 0 to 2) (default auto)	Default('auto')
out_range	Int | Literal['auto', 'unknown', 'full', 'limited', 'jpeg', 'mpeg', 'tv', 'pc'] | Default	Set in/output YCbCr sample range. This allows the autodetected value to be overridden as well as allows forcing a specific value used for the output and encoder. If not specified, the range depends on the pixel format. Possible values: @end table	Default('auto')
in_v_chr_pos	Int	input vertical chroma position in luma grid/256 (from -513 to 512) (default -513)	Default('-513')
in_h_chr_pos	Int	input horizontal chroma position in luma grid/256 (from -513 to 512) (default -513)	Default('-513')
out_v_chr_pos	Int	output vertical chroma position in luma grid/256 (from -513 to 512) (default -513)	Default('-513')
out_h_chr_pos	Int	output horizontal chroma position in luma grid/256 (from -513 to 512) (default -513)	Default('-513')
force_original_aspect_ratio	Int | Literal['disable', 'decrease', 'increase'] | Default	Enable decreasing or increasing output video width or height if necessary to keep the original aspect ratio. Possible values: @end table One useful instance of this option is that when you know a specific device's maximum allowed resolution, you can use this to limit the output video to that, while retaining the aspect ratio. For example, device A allows 1280x720 playback, and your video is 1920x800. Using this option (set it to decrease) and specifying 1280x720 to the command line makes the output 1280x533. Please note that this is a different thing than specifying -1 for w or h, you still need to specify the output resolution for this option to work.	Default('disable')
force_divisible_by	Int	Ensures that both the output dimensions, width and height, are divisible by the given integer when used together with force_original_aspect_ratio. This works similar to using -n in the w and h options. This option respects the value set for force_original_aspect_ratio, increasing or decreasing the resolution accordingly. The video's aspect ratio may be slightly modified. This option can be handy if you need to have a video fit within or exceed a defined resolution using force_original_aspect_ratio but also have encoder restrictions on width or height divisibility.	Default('1')
param0	Double	Set libswscale input parameters for scaling algorithms that need them. See the ffmpeg-scaler manual for the complete documentation. If not explicitly specified the filter applies empty parameters.	Default('123456')
param1	Double	Set libswscale input parameters for scaling algorithms that need them. See the ffmpeg-scaler manual for the complete documentation. If not explicitly specified the filter applies empty parameters.	Default('123456')
eval	Int | Literal['init', 'frame'] | Default	Specify when to evaluate width and height expression. It accepts the following values: @end table Default value is init.	Default('init')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Name	Type	Description
default	VideoStream	the video stream

    extra_options: dict[str, Any] | None = None
) -> VideoStream

Detect video scene change.

This filter sets frame metadata with mafd between frame, the scene score, and forward the frame to the next filter, so they can use these metadata to detect scene change or others.

In addition, this filter logs a message and sets frame metadata when it detects a scene change by threshold.

lavfi.scd.mafd metadata keys are set with mafd for every frame.

lavfi.scd.score metadata keys are set with scene change score for every frame to detect scene change.

lavfi.scd.time metadata keys are set with current filtered frame time which detect scene change with threshold.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
threshold	Double	Set the scene change detection threshold as a percentage of maximum change. Good values are in the [8.0, 14.0] range. The range for threshold is [0., 100.]. Default value is 10..	Default('10')
sc_pass	Boolean	Set the flag to pass scene change frames to the next filter. Default value is 0 You can enable it if you want to get snapshot of scene change frames only.	Default('false')
extra_options	dict[str, Any] | None	Extra options for the filter	None

) -> AudioStream

Synthesize audio from 2 input video spectrums, first input stream represents magnitude across time and second represents phase across time. The filter will transform from frequency domain as displayed in videos back to time domain as presented in audio output.

This filter is primarily created for reversing processed showspectrum filter outputs, but can synthesize sound from other spectrograms too. But in such case results are going to be poor if the phase data is not available, because in such cases phase data need to be recreated, usually it's just recreated from random noise. For best results use gray only output (channel color mode in showspectrum filter) and log scale for magnitude video and lin scale for phase video. To produce phase, for 2nd video, use data option. Inputs videos should generally use fullframe slide mode as that saves resources needed for decoding video.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
sample_rate	Int	Specify sample rate of output audio, the sample rate of audio from which spectrum was generated may differ.	Default('44100')
channels	Int	Set number of channels represented in input video spectrums.	Default('1')
scale	Int | Literal['lin', 'log'] | Default	Set scale which was used when generating magnitude input spectrum. Can be lin or log. Default is log.	Default('log')
slide	Int | Literal['replace', 'scroll', 'fullframe', 'rscroll'] | Default	Set slide which was used when generating inputs spectrums. Can be replace, scroll, fullframe or rscroll. Default is fullframe.	Default('fullframe')
win_func	Int | Literal['rect', 'bartlett', 'hann', 'hanning', 'hamming', 'blackman', 'welch', 'flattop', 'bharris', 'bnuttall', 'bhann', 'sine', 'nuttall', 'lanczos', 'gauss', 'tukey', 'dolph', 'cauchy', 'parzen', 'poisson', 'bohman'] | Default	Set window function used for resynthesis.	Default('rect')
overlap	Float	Set window overlap. In range [0, 1]. Default is 1, which means optimal overlap for selected window function will be picked.	Default('1')
orientation	Int | Literal['vertical', 'horizontal'] | Default	Set orientation of input videos. Can be vertical or horizontal. Default is vertical.	Default('vertical')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Obtain the SSIM (Structural SImilarity Metric) between two input videos.

This filter takes in input two input videos, the first input is considered the "main" source and is passed unchanged to the output. The second input is used as a "reference" video for computing the SSIM.

Both video inputs must have the same resolution and pixel format for this filter to work correctly. Also it assumes that both inputs have the same number of frames, which are compared one by one.

The filter stores the calculated SSIM of each frame.

The description of the accepted parameters follows.

Parameters:

Name	Type	Description	Default
stats_file	String	If specified the filter will use the named file to save the SSIM of each individual frame. When filename equals "-" the data is sent to standard output.	Default(None)

) -> VideoStream

Draw subtitles on top of input video using the libass library.

To enable compilation of this filter you need to configure FFmpeg with --enable-libass. This filter also requires a build with libavcodec and libavformat to convert the passed subtitles file to ASS (Advanced Substation Alpha) subtitles format.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
filename	String	Set the filename of the subtitle file to read. It must be specified.	Default(None)
original_size	Image_size	Specify the size of the original video, the video for which the ASS file was composed. For the syntax of this option, check the "Video size" section in the ffmpeg-utils manual. Due to a misdesign in ASS aspect ratio arithmetic, this is necessary to correctly scale the fonts if the aspect ratio has been changed.	Default(None)
fontsdir	String	Set a directory path containing fonts that can be used by the filter. These fonts will be used in addition to whatever the font provider uses.	Default(None)
alpha	Boolean	Process alpha channel, by default alpha channel is untouched.	Default('false')
charenc	String	Set subtitles input character encoding. subtitles filter only. Only useful if not UTF-8.	Default(None)
stream_index	Int	Set subtitles stream index. subtitles filter only.	Default('-1')
force_style	String	Override default style or script info parameters of the subtitles. It accepts a string containing ASS style format KEY=VALUE couples separated by ",".	Default(None)
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

) -> VideoStream

Compute and draw a color distribution histogram for the input video across time.

Unlike histogram video filter which only shows histogram of single input frame at certain time, this filter shows also past histograms of number of frames defined by width option.

The computed histogram is a representation of the color component distribution in an image.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
width	Int	Set width of single color component output. Default value is 0. Value of 0 means width will be picked from input video. This also set number of passed histograms to keep. Allowed range is [0, 8192].	Default('0')
display_mode	Int | Literal['overlay', 'parade', 'stack'] | Default	Set display mode. It accepts the following values: @end table Default is stack.	Default('stack')
levels_mode	Int | Literal['linear', 'logarithmic'] | Default	Set mode. Can be either linear, or logarithmic. Default is linear.	Default('linear')
components	Int	Set what color components to display. Default is 7.	Default('7')
bgopacity	Float	Set background opacity. Default is 0.9.	Default('0.9')
envelope	Boolean	Show envelope. Default is disabled.	Default('false')
ecolor	Color	Set envelope color. Default is gold.	Default('gold')
slide	Int | Literal['frame', 'replace', 'scroll', 'rscroll', 'picture'] | Default	Set slide mode. Available values for slide is: @end table Default is replace.	Default('replace')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Name	Type	Description
default	VideoStream	the video stream

    extra_options: dict[str, Any] | None = None
) -> VideoStream

Apply threshold effect to video stream.

This filter needs four video streams to perform thresholding. First stream is stream we are filtering. Second stream is holding threshold values, third stream is holding min values, and last, fourth stream is holding max values.

The filter accepts the following option:

Parameters:

Name	Type	Description	Default
planes	Int	Set which planes will be processed, unprocessed planes will be copied. By default value 0xf, all planes will be processed.	Default('15')
timeline_options	FFMpegTimelineOption | None	Timeline options	None

    overlap: Int = Default("0"),
    init_padding: Int = Default("0"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Tile several successive frames together.

The untile filter can do the reverse.

The filter accepts the following options:

Parameters:

Name	Type	Description	Default
layout	Image_size	Set the grid size in the form COLUMNSxROWS. Range is upto UINT_MAX cells. Default is 6x5.	Default('6x5')
nb_frames	Int	Set the maximum number of frames to render in the given area. It must be less than or equal to wxh. The default value is 0, meaning all the area will be used.	Default('0')
margin	Int	Set the outer border margin in pixels. Range is 0 to 1024. Default is 0.	Default('0')
padding	Int	Set the inner border thickness (i.e. the number of pixels between frames). For more advanced padding options (such as having different values for the edges), refer to the pad video filter. Range is 0 to 1024. Default is 0.	Default('0')
color	Color	Specify the color of the unused area. For the syntax of this option, check the "Color" section in the ffmpeg-utils manual. The default value of color is "black".	Default('black')
overlap	Int	Set the number of frames to overlap when tiling several successive frames together. The value must be between 0 and nb_frames - 1. Default is 0.	Default('0')
init_padding	Int	Set the number of frames to initially be empty before displaying first output frame. This controls how soon will one get first output frame. The value must be between 0 and nb_frames - 1. Default is 0.	Default('0')
extra_options	dict[str, Any] | None	Extra options for the filter	None

            "linear",
            "gamma",
            "clip",
            "reinhard",
            "hable",
            "mobius",
        ]
        | Default
    ) = Default("none"),
    param: Double = Default("nan"),
    desat: Double = Default("2"),
    peak: Double = Default("0"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Tone map colors from different dynamic ranges.

This filter expects data in single precision floating point, as it needs to operate on (and can output) out-of-range values. Another filter, such as zscale, is needed to convert the resulting frame to a usable format.

The tonemapping algorithms implemented only work on linear light, so input data should be linearized beforehand (and possibly correctly tagged).

@example ffmpeg -i INPUT -vf zscale=transfer=linear,tonemap=clip,zscale=transfer=bt709,format=yuv420p OUTPUT @end example

Parameters:

Name	Type	Description	Default
tonemap	Int | Literal['none', 'linear', 'gamma', 'clip', 'reinhard', 'hable', 'mobius'] | Default	Set the tone map algorithm to use. Possible values are: @end table Default is none.	Default('none')
param	Double	Tune the tone mapping algorithm. This affects the following algorithms: @end table	Default('nan')
desat	Double	Apply desaturation for highlights that exceed this level of brightness. The higher the parameter, the more color information will be preserved. This setting helps prevent unnaturally blown-out colors for super-highlights, by (smoothly) turning into white instead. This makes images feel more natural, at the cost of reducing information about out-of-range colors. The default of 2.0 is somewhat conservative and will mostly just apply to skies or directly sunlit surfaces. A setting of 0.0 disables this option. This option works only if the input frame has a supported color tag.	Default('2')
peak	Double	Override signal/nominal/reference peak with this value. Useful when the embedded peak information in display metadata is not reliable or when tone mapping from a lower range to a higher range.	Default('0')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Name	Type	Description
default	VideoStream	the video stream

) -> VideoStream

Apply a wavelet based denoiser.

It transforms each frame from the video input into the wavelet domain, using Cohen-Daubechies-Feauveau 9/7. Then it applies some filtering to the obtained coefficients. It does an inverse wavelet transform after. Due to wavelet properties, it should give a nice smoothed result, and reduced noise, without blurring picture features.

This filter accepts the following options:

Parameters:

Name	Type	Description	Default
threshold	Float	The filtering strength. The higher, the more filtered the video will be. Hard thresholding can use a higher threshold than soft thresholding before the video looks overfiltered. Default value is 2.	Default('2')
method	Int | Literal['hard', 'soft', 'garrote'] | Default	The filtering method the filter will use. It accepts the following values: @end table Default is garrote.	Default('garrote')
nsteps	Int	Number of times, the wavelet will decompose the picture. Picture can't be decomposed beyond a particular point (typically, 8 for a 640x480 frame - as 2^9 = 512 > 480). Valid values are integers between 1 and 32. Default value is 6.	Default('6')
percent	Float	Partial of full denoising (limited coefficients shrinking), from 0 to 100. Default value is 85.	Default('85')
planes	Int	A list of the planes to process. By default all planes are processed.	Default('15')
type	Int | Literal['universal', 'bayes'] | Default	The threshold type the filter will use. It accepts the following values: @end table Default is universal.	Default('universal')

    show: Int = Default("0"),
    tripod: Int = Default("0"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Analyze video stabilization/deshaking. Perform pass 1 of 2, see vidstabtransform for pass 2.

This filter generates a file with relative translation and rotation transform information about subsequent frames, which is then used by the vidstabtransform filter.

To enable compilation of this filter you need to configure FFmpeg with --enable-libvidstab.

This filter accepts the following options:

Parameters:

Name	Type	Description	Default
result	String	Set the path to the file used to write the transforms information. Default value is transforms.trf.	Default('transforms.trf')
shakiness	Int	Set how shaky the video is and how quick the camera is. It accepts an integer in the range 1-10, a value of 1 means little shakiness, a value of 10 means strong shakiness. Default value is 5.	Default('5')
accuracy	Int	Set the accuracy of the detection process. It must be a value in the range 1-15. A value of 1 means low accuracy, a value of 15 means high accuracy. Default value is 15.	Default('15')
stepsize	Int	Set stepsize of the search process. The region around minimum is scanned with 1 pixel resolution. Default value is 6.	Default('6')
mincontrast	Double	Set minimum contrast. Below this value a local measurement field is discarded. Must be a floating point value in the range 0-1. Default value is 0.3.	Default('0.25')
show	Int	Show fields and transforms in the resulting frames. It accepts an integer in the range 0-2. Default value is 0, which disables any visualization.	Default('0')
tripod	Int	Set reference frame number for tripod mode. If enabled, the motion of the frames is compared to a reference frame in the filtered stream, identified by the specified number. The idea is to compensate all movements in a more-or-less static scene and keep the camera view absolutely still. If set to 0, it is disabled. The frames are counted starting from 1.	Default('0')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Video stabilization/deshaking: pass 2 of 2, see vidstabdetect for pass 1.

Read a file with transform information for each frame and apply/compensate them. Together with the vidstabdetect filter this can be used to deshake videos. See also http://public.hronopik.de/vid.stab. It is important to also use the unsharp filter, see below.

To enable compilation of this filter you need to configure FFmpeg with --enable-libvidstab.

Parameters:

Name	Type	Description	Default
input	String	Set path to the file used to read the transforms. Default value is transforms.trf.	Default('transforms.trf')
smoothing	Int	Set the number of frames (value*2 + 1) used for lowpass filtering the camera movements. Default value is 10. For example a number of 10 means that 21 frames are used (10 in the past and 10 in the future) to smoothen the motion in the video. A larger value leads to a smoother video, but limits the acceleration of the camera (pan/tilt movements). 0 is a special case where a static camera is simulated.	Default('15')
optalgo	Int | Literal['opt', 'gauss', 'avg'] | Default	Set the camera path optimization algorithm. Accepted values are: @end table	Default('opt')
maxshift	Int	Set maximal number of pixels to translate frames. Default value is -1, meaning no limit.	Default('-1')
maxangle	Double	Set maximal angle in radians (degree*PI/180) to rotate frames. Default value is -1, meaning no limit.	Default('-1')
crop	Int | Literal['keep', 'black'] | Default	Specify how to deal with borders that may be visible due to movement compensation. Available values are: @end table	Default('keep')
invert	Int	Invert transforms if set to 1. Default value is 0.	Default('0')
relative	Int	Consider transforms as relative to previous frame if set to 1, absolute if set to 0. Default value is 0.	Default('1')
zoom	Double	Set percentage to zoom. A positive value will result in a zoom-in effect, a negative value in a zoom-out effect. Default value is 0 (no zoom).	Default('0')
optzoom	Int	Set optimal zooming to avoid borders. Accepted values are: @end table Note that the value given at zoom is added to the one calculated here.	Default('1')
zoomspeed	Double	Set percent to zoom maximally each frame (enabled when optzoom is set to 2). Range is from 0 to 5, default value is 0.25.	Default('0.25')
interpol	Int | Literal['no', 'linear', 'bilinear', 'bicubic'] | Default	Specify type of interpolation. Available values are: @end table	Default('bilinear')
tripod	Boolean	Enable virtual tripod mode if set to 1, which is equivalent to relative=0:smoothing=0. Default value is 0. Use also tripod option of vidstabdetect.	Default('false')
debug	Boolean	Increase log verbosity if set to 1. Also the detected global motions are written to the temporary file global_motions.trf. Default value is 0.	Default('false')
extra_options	dict[str, Any] | None	Extra options for the filter	None

    timeline_options: FFMpegTimelineOption | None = None,
    enable: str | None = None,
    extra_options: dict[str, Any] | None = None,
) -> VideoStream

Obtain the average VIF (Visual Information Fidelity) between two input videos.

This filter takes two input videos.

Both input videos must have the same resolution and pixel format for this filter to work correctly. Also it assumes that both inputs have the same number of frames, which are compared one by one.

The obtained average VIF score is printed through the logging system.

The filter stores the calculated VIF score of each frame.

In the below example the input file main.mpg being processed is compared with the reference file ref.mpg.

@example ffmpeg -i main.mpg -i ref.mpg -lavfi vif -f null - @end example

Deinterlace the input video ("w3fdif" stands for "Weston 3 Field Deinterlacing Filter").

Based on the process described by Martin Weston for BBC R&D, and implemented based on the de-interlace algorithm written by Jim Easterbrook for BBC R&D, the Weston 3 field deinterlacing filter uses filter coefficients calculated by BBC R&D.

This filter uses field-dominance information in frame to decide which of each pair of fields to place first in the output. If it gets it wrong use setfield filter before w3fdif filter.

There are two sets of filter coefficients, so called "simple" and "complex". Which set of filter coefficients is used can be set by passing an optional parameter:

Parameters:

Name	Type	Description	Default
filter	Int | Literal['simple', 'complex'] | Default	Set the interlacing filter coefficients. Accepts one of the following values: @end table Default value is complex.	Default('complex')
mode	Int | Literal['frame', 'field'] | Default	The interlacing mode to adopt. It accepts one of the following values: @end table The default value is field.	Default('field')
parity	Int | Literal['tff', 'bff', 'auto'] | Default	The picture field parity assumed for the input interlaced video. It accepts one of the following values: @end table The default value is auto. If the interlacing is unknown or the decoder does not export this information, top field first will be assumed.	Default('auto')
deint	Int | Literal['all', 'interlaced'] | Default	Specify which frames to deinterlace. Accepts one of the following values: @end table Default value is all.	Default('all')
timeline_options	FFMpegTimelineOption | None	Timeline options	None
extra_options	dict[str, Any] | None	Extra options for the filter	None

mode	Int | Literal['row', 'column'] | Default	Can be either row, or column. Default is column. In row mode, the graph on the left side represents color component value 0 and the right side represents value = 255. In column mode, the top side represents color component value = 0 and bottom side represents value = 255.	Default('column')
intensity	Float	Set intensity. Smaller values are useful to find out how many values of the same luminance are distributed across input rows/columns. Default value is 0.04. Allowed range is [0, 1].	Default('0.04')
mirror	Boolean	Set mirroring mode. 0 means unmirrored, 1 means mirrored. In mirrored mode, higher values will be represented on the left side for row mode and at the top for column mode. Default is 1 (mirrored).	Default('true')
display	Int | Literal['overlay', 'stack', 'parade'] | Default	Set display mode. It accepts the following values: @end table Default is stack.	Default('stack')
components	Int	Set which color components to display. Default is 1, which means only luminance or red color component if input is in RGB colorspace. If is set for example to 7 it will display all 3 (if) available color components.	Default('1')
envelope	Int | Literal['none', 'instant', 'peak', 'peak+instant'] | Default	@end table	Default('none')
filter	Int | Literal['lowpass', 'flat', 'aflat', 'chroma', 'color', 'acolor', 'xflat', 'yflat'] | Default	@end table	Default('lowpass')

zmq

zmq(
    *,
    bind_address: String = Default("tcp://*:5555"),
    extra_options: dict[str, Any] | None = None
) -> VideoStream

Receive commands sent through a libzmq client, and forward them to filters in the filtergraph.

zmq and azmq work as a pass-through filters. zmq must be inserted between two video filters, azmq between two audio filters. Both are capable to send messages to any filter type.

To enable these filters you need to install the libzmq library and headers and configure FFmpeg with --enable-libzmq.

For more information about libzmq see: http://www.zeromq.org/

The zmq and azmq filters work as a libzmq server, which receives messages sent through a network interface defined by the bind_address (or the abbreviation "b") option. Default value of this option is tcp://localhost:5555. You may want to alter this value to your needs, but do not forget to escape any ':' signs (see filtergraph escaping).

The received message must be in the form: @example TARGET COMMAND [ARG] @end example

TARGET specifies the target of the command, usually the name of the filter class or a specific filter instance name. The default filter instance name uses the pattern Parsed__, but you can override this by using the filter_name@id syntax (see Filtergraph syntax).

COMMAND specifies the name of the command for the target filter.

ARG is optional and specifies the optional argument list for the given COMMAND.

Upon reception, the message is processed and the corresponding command is injected into the filtergraph. Depending on the result, the filter will send a reply to the client, adopting the format: @example ERROR_CODE ERROR_REASON MESSAGE @end example

MESSAGE is optional.

Parameters:

Name	Type	Description	Default
bind_address	String	set bind address (default "tcp://*:5555")	Default('tcp://*:5555')
extra_options	dict[str, Any] | None	Extra options for the filter	None

Returns:

Name	Type	Description
default	VideoStream	the video stream

Scale (resize) the input video, using the z.lib library: https://github.com/sekrit-twc/zimg. To enable compilation of this filter, you need to configure FFmpeg with --enable-libzimg.

The zscale filter forces the output display aspect ratio to be the same as the input, by changing the output sample aspect ratio.

If the input image format is different from the format requested by the next filter, the zscale filter will convert the input to the requested format.

Parameters:

Name	Type	Description	Default
w	String	Output video width	Default(None)
h	String	Set the output video dimension expression. The command accepts the same syntax of the corresponding option. If the specified expression is not valid, it is kept at its current value.	Default(None)
