Get stored dimension from bitstream.
If the width/height is the standard one then it's coded as a 3-bit index. Otherwise it is coded as escaped 8-bit portions.

RV40 loop filtering function.
< current macroblock and its neighbours types
flags indicating that macroblock can be filtered with strong filter it is set only for intra coded MB and MB with DCs coded separately
< MB filter clipping value calculated from filtering strength
coded block patterns for luma part of current macroblock and its neighbours Format: LSB corresponds to the top left block, each nibble represents one row of subblocks.
coded block patterns for chroma part of current macroblock and its neighbours Format is the same as for luma with two subblocks in a row.
This mask represents the pattern of luma subblocks that should be filtered in addition to the coded ones because because they lie at the edge of 8x8 block with different enough motion vectors
