Description
This processes the specified NAL-unit. This seems to always start with the 3-byte NAL prefix(00 00 01). Following that is the actual NAL-unit.
After the parameter-set initialization, each time this command is used it can't be used again until MVDSTD:ControlFrameRendering type0 finishes operations.
This is only used for H.264, not color-conversion.
