    wavpack : extract channel information from the bitstream

    This way we don’t require the caller to parse the block header. It also
    
allows the channel configuration to change mid-stream.

  • ffmpeg mp4 to hls vod with extract segment duration without re-encoding

    11 juillet 2021, par Jeremy

    Hello I have h264 mp4 files. What I want to do is convert it to hls without re-encoding. This can be achieve by :

    


    ffmpeg -i input.mp4 -c copy -force_key_frames "expr:gte(t,n_forced*4)" -hls_time 4 -hls_playlist_type vod -hls_segment_type mpegts vid.m3u8


    


    But this problem with this is that it doesn't create extract segment duration :

    


    $ for f in *.ts; do echo -n "$f,"; ffprobe -v error -show_entries format=duration -sexagesimal -of csv=p=0 "$f"; done
vid0.ts,0:00:04.837700
vid1.ts,0:00:05.587200
vid2.ts,0:00:06.006200
vid3.ts,0:00:01.368200
vid4.ts,0:00:02.693867


    


    I don't believe I can't insert keyframes without encoding.

    


    When I run :

    


    ffmpeg -i input.mp4 -codec:v libx264 -force_key_frames "expr:gte(t,n_forced*4)" -hls_time 4 -hls_playlist_type vod -hls_segment_type mpegts vid.m3u8


    


    its works but this is resource intensive as it re-encode the video.

    


    So I am looking for the best way to achieve this while using minimal resource as possible.
