Detailed Description

Sierra VMD video 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 video decoder outputs PAL8 colorspace data. The decoder expects a 0x330-byte VMD file header to be transmitted via extradata during codec initialization. Each encoded frame that is sent to this decoder is expected to be prepended with the appropriate 16-byte frame information record from the VMD file.
