Sierra VMD audio decoder by Vladimir "VAG" Gneushev (vagsoft at mail.ru) for more information on the Sierra VMD format, visit: http://www.pcisys.net/~melanson/codecs/
The audio decoder, expects each encoded data chunk to be prepended with the appropriate 16-byte frame information record from the VMD file. It does not require the 0x330-byte VMD file header, but it does need the audio setup parameters passed in through normal libavcodec API means.
