Yes I should not have done it this way, I was just trying to make it
build. A proper fix is needed for the same thing in other places.

Just increasing VL_MAX_REF_FRAMES is probably not going to break
anything but the mpeg2 decoder would then have unused motion vectors
processed at different places.
These defines are mostly applying to the mpeg2 decoder, so it makes
sense to create more defines I guess ?
VL_MAX_REF_FRAMES : H.264 can have 16, VP8 4, mpeg1/2 divx and vc1 can have 2.
BLOCK_WIDTH : Block size is 8x8 for for some mpeg codecs, VP8 uses 8x8
and H.264 can have 8x8 and 4x4 at the same time.
VL_MAX_PLANES : H.264 can have only one plane when using 4:0:0

Thanks. I am still trying to get libav to send the VP8 data through
VDPAU, but as soon as I dive into the vp8 decoder I will have a lot of
questions for sure ;-)
