 Summary of the bug:
 In cases of poorly managed HLS streams where one of the variant streams
 inside the m3u8 playlist are down, ffmpeg fails to play as soon as it sees
 a 404 error for one of the variant streams, while iOS ignores the dead
 stream and just plays it with the ones that work.
 How to reproduce:

 Since the stream in question that I use is only available weekdays for one
 hour a day, the output above is with a sample I created that intentionally
 has the same error so you can reproduce.
