On by default unless standard input isused as an input. Prints execution graph details to stderr in the format set via -print_graphs_format. Specify the preset for matching stream(s). Generally useful to avoid corrupted yet decodable packets in live streaminginputs. Create the filtergraph specified by filtergraph and use it tofilter the stream. E.g. to create an scalable 5.1 IAMF file from several WAV input files
Clips the RGB values to the 0, 1 range when building the gamma transfer LUTs. Output levels allows manual selection of a constrained output level range. Remove all color information for all RGB colors except for certain one.
158.1 Commands
- If not specified the type is guessed from the list file name suffix.
- The index of the input plane to be used as the third output plane.
- Indicates whether the audio has passed through HDCD A/Dconversion.
This is the QSV variant of the xstack filter. Default is 7, equal to p.Must be odd number in range 0, 99. Set patch size for a specific component. Default is 1.0, equal to s.Must be in range 0.0, 100.0. Must be odd number in range 0, 99.
59.1 Commands
- Time of the first frame after command was applied or time of the first frame if no commands.
- So DeckLink 8K Pro support four profiles.
- The computed values for x and y.
- Ifusing ffmpeg, select the appropriate device with the -filter_hw_deviceoption or with the derive_device option.
Set color based on point closest to the origin of the iterations. Set the inner coloring mode, that is the algorithm used to draw theMandelbrot fractal internal region. Generate a Mandelbrot set fractal, and progressively zoom towards thepoint specified with start_x and start_y.
Essentially, for a givenparameter x, every color value below x will be mapped linearly,while pin up online casino higher values get non-linearly tone-mapped. The configurable contrastparameter influences the slope of the linear output segment, defaulting to1.0 for no increase/decrease in contrast. Performs no tone-mapping, just clips out-of-range colors. Do nothing, simply clip out-of-range colors to the RGB volume. Highervalues result in peak detection becoming less responsive to changes in theinput.
Higher values result in semi-transparent pixels, with a higher transparencythe more similar the pixels color is to the key color. Literal colors like “green” or “red” don’t make sense with this enabled anymore.This can be used to pass exact YUV values as hexadecimal numbers. Blend percentage.0.0 makes pixels either fully gray, or not gray at all.Higher values result in more preserved color.
The filter stores the calculated correlation of each frame in frame metadata. Obtain the correlation between two input videos. By using it, providing inputimages by another video source or an input video is not required. Some filters generate output images with additional padding depending on therespective filter kernel.

For tensorflow backend, you can set its configs with sess_config options,please use tools/python/tf_sess_config.py to get the configs of TensorFlow backend for your system. It works together with another filterwhich converts the pixel format of the Frame to what the dnn network requires. For tensorflow backend, you can set its configs with sess_config options,please use tools/python/tf_sess_config.py to get the configs for your system. Displace pixels as indicated by second and third input stream.

The count of the input frame for video or audio, starting from 0. This works by comparing the frame pts against the lavf.concat.start_timeand the lavf.concat.duration packet metadata values which are alsopresent in the decoded frames. The concat demuxer can select only part of a concat input file by setting aninpoint and an outpoint, but the output packets may not be entirely containedin the selected interval. Segment works on video frames, asegment on audio samples. If file option is not set, output is written to the logwith AV_LOG_INFO loglevel.
23.1 Commands
Keyframe interval.A keyframe is inserted at least every -g frames, sometimes sooner. This option is only effective fornon-mono streams. The default also disables the surround masking and LFE bandwidthoptimizations in libopus, and requires that the input contains 8 channels orfewer. Smallerframe sizes achieve lower latency but less quality at a given bitrate.Sizes greater than 20ms are only interesting at fairly low bitrates.The default is 20ms. Valid options are integers inthe 0-10 range. The lame–abr sets the target bitrate, while this options onlytells FFmpeg to use ABR still relies on b to set bitrate.
Virtually extract a segment of a file or another stream.The underlying stream must be seekable. Set input and output encoding parameters, which are expressed by abase64-encoded representation of a binary block. Select input and output encoding suites. The range for this option is integers in the0 – INT_MAX. Stream API (default, when this option is false).
Setting this toN means one frame in every batch of N frames will be dropped.Default is 5. Set the number of frames from which one will be dropped. Set size of block, allowed range is from 4 to 512.
70.1 Commands
Specify the size (width and height) of the buffered video frames. Buffer video frames, and make them available to the filter chain. 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 video. See xstack.Moreover, this permits the user to supply output size for each input stream. Controls the size of the smoothing window (the number of frames buffered to determine motion information from).
Set the output slide method. Set the output visual mode. Acceptable range is 0, 10. The default is 0 (disabled). Set attack time in seconds.
Number of pixels to fill from bottom border. Number of pixels to fill from top border. Number of pixels to fill from right border. Number of pixels to fill from left border.
