NOTE:
1. When demux is disabled, host has to fill out the descriptor buffer for each slice/NALU. For VC1, after constructing all the
descriptors, one dummy descriptor needs to be created with start code suffix byte 0x82 (ID [7:0] = 0x82).
2. For both H264 and VC1, after all descriptor entries (including VC1 dummy descriptor entry), zero word is written to
descriptor table to indicate end of descriptors. word is written to descriptor table to indicate end of descriptors.
ID[7:0]
ID: start code suffix byte (first byte after start code: NALU header byte for H.264 and 0x82 for VC1)
Offset: (nal start address) & 0x0
Start_addr: ((nal start address) >> 3) << 1
Unit_size: size of NALU
