Comment (by mav):
My player will check buffer fill percentage every 30 seconds or so. If
buffer fill > 90% it will switch to higher bitrate, if buffer fill < 20%,
it will switch to lower bitrate.
The problem with ffmpeg currently - I cannot disable stream by setting
AVDISCARD_ALL flag after I get packets from it, it still downloads
segments from unneeded bitrates.
See the check in hls.c recheck_discard_flags() function. It checks for
discard flag only on first packet in stream. After this - it just ignores
discard flag.
