  • FFmpeg : Add alpha channel to a video using a PNG mask

    7 avril 2016, par Rodrigo Polo

    I saw that FFmpeg can merge/blend two videos with alpha channel and can encode video with alpha channel using the qtrle codec, but, It is possible to apply a PNG file mask, either a black and white or a PNG with an alpha channel to a video in order to have a video with the alpha channel of the PNG applied ?

    Here is the concept in images

    Original video :
    Original video

    PNG file with alpha channel, the "mask" :
    PNG file with alpha channel

    And the result :
    Result

    Or even a black and white image as a mask for alpha channel :
    bnw image

    Any help would be appreciated, thank you !

  • libopusenc : Add channel mapping family argument

    15 juin 2016, par Michael Graczyk
    libopusenc : Add channel mapping family argument

    The default value of -1 indicates that ffmpeg should determine the channel
    
mapping automatically, which was the behavior before this commit.
    

    Unless the -mapping_family argument is provided, behavior is unchanged.

    This, along with the next patch, are the last missing pieces to being
