 I believe there is currently no way to dump the transport stream(s) of a
 hls stream using FFmpeg.
 {{{
 $ ffmpeg -f lavfi -i testsrc=d=100 -vcodec mpeg1video out.m3u8
 }}}
 The following only dumps the playlist to the output file:
 {{{
 $ aviocat out.m3u8 out
 }}}
 Dumping streams with {{{-f data}}} is currently broken but it also used to
 only dump the playlist:
 {{{
 $ ffmpeg -f data -i out.m3u8 -map 0 -f data -codec copy out
