Possible combinations for bitplane decoding operation:
+ To use the hardware bitplane decoder, define VC1_BITPLANE_HARDWARE in the
preprocessor definitions of um_drivers, set REFDEC_BITPLANE_DECODER to 1 and
VC1_INTERLEAVED_BITPLANE to 0.
+ To use the software bitplane decoder, don't define VC1_BITPLANE_HARDWARE.
There are two implementations of the decoder:
- To use the VC1 reference decoder implementation, set
REFDEC_BITPLANE_DECODER to 1.
- Otherwise, set REFDEC_BITPLANE_DECODER to 0.
+ When using the software bitplane decoder, the data can be sent to
the hardware in two formats.
- Set VC1_INTERLEAVED_BITPLANE to 1, if using the three-plane
interleaved format.
- Otherwise, set VC1_INTERLEAVED_BITPLANE to 0.
