avformat/hls: do not use sequence numbers for packet ordering
As per spec 3.4.3 ("A client MUST NOT assume that segments with the same sequence number in different Media Playlists contain matching content.") we cannot use sequence numbers for packet ordering. This can be seen e.g. in the subtitle streams of bipbop_16x9_variant.m3u8 that have considerably longer segments and therefore different numbering. Since the code now exclusively syncs using timestamps that may wrap, add some additional checking for that. According to the HLS spec all the timestamps should be in 33-bit MPEG format and synced together. v2: cleaner wrap detection v3: further wrap detection improvements Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi>
