  • ffmpeg hls muxer is missing codec info in master playlist when codecs are copied from input

    21 septembre 2021, par dogan

    ffmpeg hls muxer has the option to set master playlist but the created playlist is missing the important codec information.

    


    Example :

    


    ffmpeg -hide_banner -i <input /> -c copy -f hls -master_pl_name master.m3u8  stream.m3u8&#xA;

    &#xA;

    Expected :

    &#xA;

    #EXTM3U&#xA;#EXT-X-VERSION:3&#xA;#EXT-X-STREAM-INF:BANDWIDTH=77595,RESOLUTION=1280x720,CODECS="avc1.64001f,mp4a.40.2"&#xA;stream.m3u8&#xA;

    &#xA;

    Instead I get this

    &#xA;

    #EXTM3U&#xA;#EXT-X-VERSION:3&#xA;#EXT-X-STREAM-INF:BANDWIDTH=77595,RESOLUTION=1280x720&#xA;stream.m3u8&#xA;

    &#xA;

    Is there a way to make ffmpeg set the codec info in playlist from the input source ? It works as expected if I encode the input using libx264 but I do not want to do any expensive encoding but copy the codecs from the input.

    &#xA;
