* Radius Cinepak Video Decoder
|
||||
*
|
||||
* Dr. Tim Ferguson, 2001.
|
||||
* For more details on the algorithm:
|
||||
* http://www.csse.monash.edu.au/~timf/videocodec.html
|
||||
*
|
||||
* This is basically a vector quantiser with adaptive vector density. The
|
||||
* frame is segmented into 4x4 pixel blocks, and each block is coded using
|
||||
* either 1 or 4 vectors.
|
||||
*
|
||||
* There are still some issues with this code yet to be resolved. In
|
||||
* particular with decoding in the strip boundaries.
