  • avcodec/ac3enc : Don't presume ch_layout to be AV_CHANNEL_ORDER_NATIVE

    avcodec/ac3enc : Don't presume ch_layout to be AV_CHANNEL_ORDER_NATIVE

    It is perfectly legal for users to use a custom layout
    
that is equivalent to a supported native one.
    
In this case the union in AVChannelLayout is not an uint64_t mask,
    
but a pointer to a custom map.

    I have compiled ffmpeg with the guide How To Compile FFmpeg and x264 on Ubuntu.

    Now I'm trying upload a .mp4 file to encode. However I get this error now :

  • Multiply the video with a scalar with FFMPEG

    16 novembre 2020, par Terpsiphone

    I have to adjust a video which was too dark. In openCV, I simply used Img.Mul() to multiply each of the RGB band with a same scalar and got good result.

    &#xA;

    Could one do the equivalent operation with FFMPEG ? I tried eq with contrast and brightness, but it was not quite the same thing.

    &#xA;

    Edit : thanks to a clue in @VC.One's answer below I was able to emulate Img.Mul() with :

    &#xA;

    ffmpeg -i input.file -vf colorlevels=rimax=0.5:gimax=0.5:bimax=0.5 -c:a copy output.file&#xA;

    &#xA;
