Comment (by ARQfBfnD):
Apple specifies:
> Important: Playlists that specify byte range media segments require
protocol version 4. In addition, they must include EXT-X-TARGETDURATION
and EXT-X-MEDIA-SEQUENCE tags, and the media URI must reside on a separate
line.
Your last example had #EXTINF values that varied a lot (9, 3, 3, 6) from
the TARGETDURATION 10. This is ok, IF:
> The server MUST divide the source media into individual Media
> Segments whose duration is less than or equal to a constant target
> duration. Segments that are longer than the planned target duration
> can trigger playback stalls and other errors.
> The server SHOULD attempt to divide the source media at points that
> support effective decode of individual Media Segments, e.g. on packet
> and key frame boundaries.
