6b4b73e75d 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

8fd6875c83 avformat/hls: do not care about stream start timestamps
While selecting a packet to return to caller in read_packet(), the code
corrects the timestamps for starting timestamps.

However, this is wrong, since for live streams the initial timestamps
might differ just because of the time delay between the retrieval of the
various Media Playlists.

Fortunately, spec 6.2.4 mandates that all variant streams must have
matching timestamps, so we do not need to correct for initial
timestamps.

Drop the correction code.

Note that ID3 timestamps were previously ignored, so this code was
previously actually needed.

4e85202bcc avformat/hls: improve segment selection when restarting list reception
Improve selection of the segment sequence number when restarting the
reception of a playlist after it was suspended due to being unneeded
(due to discard flags).

The current code assumes that each playlist contains matching data with
the same sequence number, while spec 3.4.3 specifically says that that
is not the case. Often subtitle playlists also have longer target
durations as well, causing the selection to be completely wrong.

Instead prefer using the playlist segment duration information for
non-live playlists, and other means if that is not possible.

61e1a70278 avformat/hls: track seeking on a per-playlist basis
Seeking needs to be tracked on a per-playlist basis, since the resyncing
code in hls_read_packet() has to sync each playlist to the seek
timestamp instead of stopping after the first playlist has reached it.

edf4406c4d avformat/hls: add support for alternative renditions
HLS protocol version 4 added alternative renditions to the
specification (e.g. alternative audio tracks).

The EXT-X-MEDIA tags can also contain metadata for "renditions" (i.e.
tracks) of the main Media Playlist.

Add support for those.

Note that the same rendition (AVStream) may be associated with multiple
variants (AVPrograms).

Alternative subtitle tracks will require additional work and are
therefore not enabled yet.
