Hi all,

This patchset adds support for the APM files used by Rayman 2.

It has been tested against all *.apm files in the game folder.

v3:
  - simplify the decoder

v2:
  - Change extradata to use AV_{W,R}L32 instead of AV_{W,R}N32
  - fix version
  - add probe function
  - removed an unnecessary `n = 0`

Zane

Zane van Iperen (2):
  avcodec: add decoder for Rayman 2's ADPCM variant
  avformat: add demuxer for Rayman 2's APM format
