[FFmpeg-devel] [PATCH 0/5] Fix adpcm_swf support in WAV.

[Zane van Iperen]

adpcm_swf support in WAV is completely broken. block_align isn't set correctly, so
the demuxer gives incorrect packets to the decoder. The encoder doesn't provide a
value for block_align, so it's set to 1.

All of this has no bearing on (de)muxing to FLV.

See https://trac.ffmpeg.org/ticket/5829.

Zane van Iperen (5):
  avformat/wav: prevent muxing adpcm_swf with a variable block size
  avcodec/adpcm_swf: support decoding multiple fixed-sized blocks at
    once
  avcodec/adpcm_swf: set block_align when encoding
  avcodec/adpcmenc: cosmetics
  fate: add test for adpcm_swf in wav
