  • FFMPEG support for HLS v4 and v5

    5 février 2015, par omkar

    As I understand latest FFMPEG version 2.0.1 supports till HLS version 3.

    After going through draft specifications for HLS :

    New features introduced in HLS V4 are :

    • Segments with bit range support with tag EXT-X-BYTERANGE
    • Support for fast forward and fast rewind with tags EXT-X-I-FRAMES-ONLY and EXT-X-I-FRAME-STREAM-INF
    • Alternate media option with tag EXT-X-MEDIA

    New features introduced in HLS V5 are :

    • Introduction of new attributes KEYFORMAT and KEYFORMATVERSIONS for tag EXT-X-KEY
    • Introduction of tag EXT-X-MAP
    • Support for subtitles by introduction of SUBTITLES value for attribute TYPE of tag EXT-X-MEDIA.

    Wanted to know which of the above features are planned to be implemented in FFMPEG library in near future ? It will be great if you share the expected delivery dates or versions for these features.

    Thanks in advance.
