  • avutil/mem : Correct documentation of av_fast_*alloc(z)

    avutil/mem : Correct documentation of av_fast_*alloc(z)

    The current wording regarding size and min_size is completely wrong and
    
ignores that min_size is indeed only a desired minimal size, not the
    
actually allocated size.

  • 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 :

    &#xA;

    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&#xA;

    &#xA;

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

    &#xA;

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

    &#xA;

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

    &#xA;

    When I run :

    &#xA;

    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&#xA;

    &#xA;

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

    &#xA;

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

    &#xA;
