* avcodec/vc1: fix overlap filter for frame interlaced picturesJerome Borsboom2018-06-291-14/+72
| | | | | | | | | | The overlap filter is not correct for vertical edges in frame interlaced I and P pictures. When filtering macroblocks with different FIELDTX values, we have to match the lines at both sides of the vertical border. In addition, we have to use the correct rounding values, depending on the line we are filtering. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>

* avcodec/vc1: fix overlap and loop filtering for Simple and Main profileJerome Borsboom2018-06-161-15/+20
| | | | | | | | | Overlap filtering I and BI frames for Simple and Main profile is only dependent on PQUANT. Restrict testing for CONDOVER and OVERFLAGS to advanced profile. Change from mb_width to end_mb_x in ff_vc1_i_loop_filter to avoid breaking the Microsoft Screen 2 decoder. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>
* avcodec/vc1: fix overlap smoothing filter for P framesJerome Borsboom2018-06-161-25/+35
| | | | | | | | | | | The v_overlap_filter needs to run on the colocated block of the previous macroblock. For the luma plane, the colocated block is located two blocks on the left instead of one. In addition, the overlap filter needs to run on the non-edge blocks of the first macroblock row and column. Fixes ticket #7171. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>
* avcodec/vc1: fix out of bounds access of overlap filterJerome Borsboom2018-04-261-3/+3
| | | | | | | Overlap filtering of the first row and first column must be guarded for out of bounds access of v->over_flags_plane. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl>
