From d85c9b036e65afa05dcc8fbf37813ef4a05db1f3 Mon Sep 17 00:00:00 2001 From: "Ronald S. Bultje" Date: Tue, 12 Mar 2013 07:28:12 -0700 Subject: [PATCH] vp3/x86: use full transpose for all IDCTs. This way, the special IDCT permutations are no longer needed. Bfin code is disabled until someone updates it. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code.
