721d57e608 vp56: Separate VP5 and VP6 dsp initialization 
VP5 has no arch-specific optimizations (nor will it get some in the
future), so it makes no sense to try to share dsp init code with VP6.

d9d26a3674 vp56: Change type of stride parameters to ptrdiff_t 
This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.

41a10f3ba1 vp6: Support cropping to AVCodecContext.width/height 
In these cases, there is no extradata but only the properly set
width/height values by the demuxer.

This makes sure VP6 in F4V files is cropped properly.

This is similar to what is done for H264 for letting the container
width/height override what's in the bitstream, since 30f515091.

015821229f vp3: Use full transpose for all IDCTs 
This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.

Also remove the unused type == 0 cases from the plain C version
of the idct.

5e1ba34bbb VP56: move vp56_edge_filter to new VP56DSPContext 
Using macro templates allows the vp[56]_adjust functions to be
inlined instead of called through function pointers.  The new
function pointers enable optimised implementations of the filters.

4% faster VP6 decoding on Cortex-A8.
