| | | | | | | | | | | | In vc1_decode_i_blocks_adv mquant needs to be reset to its default value for each macroblock, instead of once at the beginning of the slice. DQPROFILE specifies which macroblocks can have an alternative quantizer step size. When DQPROFILE specifies edges, the selection is applicable to the edges of the picture. Slice edges are not selected by DQPROFILE. Signed-off-by: Jerome Borsboom <jerome.borsboom@carpalis.nl> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
