*
|
|
* Note about using the Xan DPCM decoder: Xan DPCM is used in AVI files
|
|
* found in the Wing Commander IV computer game. These AVI files contain
|
|
* WAVEFORMAT headers which report the audio format as 0x01: raw PCM.
|
|
* Clearly incorrect. To detect Xan DPCM, you will probably have to
|
|
* special-case your AVI demuxer to use Xan DPCM if the file uses 'Xxan'
|
|
* (Xan video) for its video codec. Alternately, such AVI files also contain
|
|
* the fourcc 'Axan' in the 'auds' chunk of the AVI header.
