Claim:
1. A method comprising: obtaining a first set of picture buffering parameters associated with a current picture of an encoded video bitstream, the first set of picture buffering parameters identifying a set of one or more reference pictures for use in decoding the current picture by a graphics processor during normal playback, the graphics processor having a buffer memory for storing reference pictures; receiving the set of one or more reference pictures in the buffer memory; revising the first set of picture buffering parameters into a second set of picture buffering parameters for use in decoding the current picture by the graphics processor, the second set of picture buffering parameters identifying a different set of one or more reference pictures than the first set of picture buffering parameters, the different set of one or more reference pictures including at least one reference picture not currently stored in the buffer memory of the graphics processor, the set of one or more reference pictures in the buffer memory being sufficient to decode the at least one reference picture not currently stored in the buffer memory; and transferring the second set of picture buffering parameters to the graphics processor for decoding the current picture.
