* qatar/master: (22 commits)
  prores: add FATE tests
  id3v2: reduce the scope of some non-globally-used symbols/structures
  id3v2: cosmetics: move some declarations before the places they are used
  shorten: remove the flush function.
  shn: do not allow seeking in the raw shn demuxer.
  avformat: add AVInputFormat flag AVFMT_NO_BYTE_SEEK.
  avformat: update AVInputFormat allowed flags
  avformat: don't unconditionally call ff_read_frame_flush() when trying to seek.
  truespeech: use sizeof() instead of hardcoded sizes
  truespeech: remove unneeded variable, 'consumed'
  truespeech: simplify truespeech_read_frame() by using get_bits()
  truespeech: decode directly to output buffer instead of a temp buffer
  truespeech: check to make sure channels == 1
  truespeech: check for large enough output buffer rather than truncating output
  truespeech: remove unneeded zero-size packet check.
  mlpdec: return meaningful error codes instead of -1
  mlpdec: remove unnecessary wrapper function
  mlpdec: only calculate output size once
  mlpdec: validate that the reported channel count matches the actual output channel count
  pcm: reduce pointer type casting
