| | | | | | | | | | | | | | | | | | | | | | needed Now it can use different references for those blocks and even use averaging. This fixes several chroma artifacts in several videos. Signed-off-by: Martin Storsjö <martin@martin.st>

| * vc1dec: Redesign the intensity compensationMichael Niedermayer2013-05-28
| | | | | | | | | | | | | | | | | | | | | | Use the intensity-compensated reference frame for subsequent fields/B-frames. Since we currently don't change the reference frame we have to maintain lookup tables for intensity compensation in the following dependent frames. Signed-off-by: Martin Storsjö <martin@martin.st>
| * vc1dec: Shuffle field MVs after decoding, not beforeMichael Niedermayer2013-05-28
| | | | | | | | | | | | | | | | | | | | | | | | This simplifies the code since copying MVs to the reference is not needed anymore (and maybe something about fixing artifacts). Also remove the unused mv_f_last. Fixes a small number of artifacts in black_screen_VC-1.mkv and several more artifacts in other videos. Signed-off-by: Martin Storsjö <martin@martin.st>

| * vc1dec: Update destination pointers in context for fieldsMichael Niedermayer2013-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces a large number of checks for the second field by fixing the pointers when they are setup. This should also fix I/BI field pictures. Changes checksums for vc1_sa10143, the file becomes slightly closer to what the reference decoder outputs.
