#2328 open defect

HLS m3u8 streams keep freezing hiccup at new segments

Reported by: curaga Owned by: reimar
Priority: normal Component: undetermined
Version: HEAD Severity: major
Keywords: Cc:
Blocked By: Blocking:
Reproduced by developer: no Analyzed by developer: no


Summary of the bug:
Every HLS stream freezes when it goes to a new chunk. The freeze lasts a second or two, and since the chunks are often just a couple seconds long, this makes HLS streams unwatchable.

I think mplayer should buffer a few seconds of the stream, so that a couple second freeze would not be seen.

"skipping N segments ahead, expired from playlists" is printed every time the freeze happens, with varying numbers in N.

Test with streams from (SFW) or chaturbate (NSFW).

How to reproduce:

% mplayer https://somestream
MPlayer SVN-r37940-5.2.0

As of today it's still freezing while provided with a direct hls url and that between each segment download (-cache is ignored).
I did work around with a ffmpeg pipe:
ffmpeg -i "$hls_url" -f matroska -c:v:0 copy -c:a:0 pcm_f32le pipe:1 </dev/null 2>&0 | mplayer -hardframedrop -softvol -vo gl -cache 16384 -

With twitch for instance, I got on high quality stream A/V desync.
The matroska format was the only one to work, and I had to decode aac directly in ffmpeg binary.
