* qatar/master:
  FATE: Add ZeroCodec test
  oggparseogm: fix order of arguments of avpriv_set_pts_info().
  pngenc: better upper bound for encoded frame size.
  aiffdec: set block_duration to 1 for PCM codecs that are supported in AIFF-C
  aiffdec: factor out handling of integer PCM for AIFF-C and plain AIFF
  aiffdec: use av_get_audio_frame_duration() to set block_duration for AIFF-C
  aiffdec: do not set bit rate if block duration is unknown
  wmall: output packet only if we have decoded some samples
