Comment:

 Before da7759b3579de3e98deb1ac58e642b861280ba54 the EXT-X-BYTERANGE in the
 playlist weren't handled at all so FFmpeg would just play back the entire
 file 6 times (there are 6 segments in the playlist), which I guess is a
 better result from user's perspective than not working at all ;)

 The playlist seems to contain some unsupported feature(s) causing some
 bytes to be missing from the stream and thus demuxing fails, I'll take a
 look at implementing them.
