H.264 Slice Group Map Buffer When VAPictureParameterBufferH264::num_slice_group_minus1 is not equal to 0, A slice group map buffer should be sent for each picture if required. The buffer is sent only when there is a change in the mapping values. The slice group map buffer map "map units" to slice groups as specified in section 8.2.2 of the H.264 spec. The buffer will contain one byte for each macroblock in raster scan orderH.264 Slice Parameter Buffer
| unsigned short VASliceParameterBufferH264::slice_data_bit_offset |
Bit offset from NAL Header Unit to the begining of slice_data().
This bit offset is relative to and includes the NAL unit byte and represents the number of bits parsed in the slice_header() after the removal of any emulation prevention bytes in there. However, the slice data buffer passed to the hardware is the original bitstream, thus including any emulation prevention bytes.
