    -ffmpeg.colorchannelmixer(parent, *args, **kwargs)
    +ffmpeg.colorchannelmixer(parent_node, *args, **kwargs)

    Adjust video input frames by re-mixing color channels.

    -

    FFmpeg colorchannelmixer filter

    +

    Official documentation: colorchannelmixer

    -ffmpeg.concat(*parents, **kwargs)
    -
    +ffmpeg.concat(*parent_nodes, **kwargs) +

    Concatenate audio and video streams, joining them together one after the other.

    +

    The filter works on segments of synchronized video and audio streams. All segments must have the same number of +streams of each type, and that will also be the number of streams at output.

    +
    +++ + + + +
    Parameters:unsafe – Activate unsafe mode: do not fail if segments have a different format.
    +

    Related streams do not always have exactly the same duration, for various reasons including codec frame size or +sloppy authoring. For that reason, related synchronized streams (e.g. a video and its audio track) should be +concatenated at once. The concat filter will use the duration of the longest stream in each segment (except the +last one), and if necessary pad shorter audio streams with silence.

    +

    For this filter to work correctly, all segments must start at timestamp 0.

    +

    All corresponding streams must have the same parameters in all segments; the filtering system will automatically +select a common pixel format for video streams, and a common sample format, sample rate and channel layout for +audio streams, but other settings, such as resolution, must be converted explicitly by the user.

    +

    Different frame rates are acceptable but will result in variable frame rate at output; be sure to configure the +output file to handle it.

    Parameters:
      +
    • x – Set the expression for the x coordinates of the overlaid video on the main video. Default value is 0. In +case the expression is invalid, it is set to a huge value (meaning that the overlay will not be displayed +within the output visible area).
      • +
    • y – Set the expression for the y coordinates of the overlaid video on the main video. Default value is 0. In +case the expression is invalid, it is set to a huge value (meaning that the overlay will not be displayed +within the output visible area).
      • +

      The action to take when EOF is encountered on the secondary input; it accepts one of the following +values:

      +
        +

        • +
      • endall: End both streams.

      • pass: Pass the main input through.
        • +
      +
      • +
    • eval –

      Set when the expressions for x, and y are evaluated. +It accepts the following values:

      +
        +
      • +
        init: only evaluate expressions once during the filter initialization or when a command is
        +
        processed
        +
        +
        • +

    • rgb (deprecated) – If set to 1, force the filter to accept inputs in the RGB color space. Default value is 0. +This option is deprecated, use format instead.
      • +
    • repeatlast – If set to 1, force the filter to draw the last overlay frame over the main input until the end of +the stream. A value of 0 disables this behavior. Default value is 1.
