Detailed Description

Interplay MVE Video Decoder by Mike Melanson (melanson@pcisys.net) For more information about the Interplay MVE format, visit: http://www.pcisys.net/~melanson/codecs/interplay-mve.txt This code is written in such a way that the identifiers match up with the encoding descriptions in the document.

This decoder presently only supports a PAL8 output colorspace.

An Interplay video frame consists of 2 parts: The decoding map and the video data. A demuxer must load these 2 parts together in a single buffer before sending it through the stream to this decoder.
