fate: Set the bitexact flag for vp3/vp5/vp6 tests · 6add6272

vp3: Use full transpose for all IDCTs · 01582122

Ronald S. Bultje authored Mar 12, 2013

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.

vp3: bfin: Transpose the IDCTs · 5941978e

Martin Storsjö authored Apr 03, 2013

While this change isn't bitexact, the IDCTs weren't bitexact to
start with either.

This simplifies decoupling vp3 from dsputil.
