[FFmpeg-devel] [PATCH] Unbreak Altivec PPC optimizations

[Guillaume POIRIER]

Hello folks,

Now that we have a "all or none" situation regarding the
implementation of  h264_idct8_add, h264_idct8_add4 (same for
h264_idct_add, h264_idct_add16, h264_idct_add16intra, h264_idct_add8),
Altivec-enabled builds lead to corrupt picture.

Since it will take time for me (or anyone else!) to implement all of
them, I'd like to suggest the attached patch to temporarily improve
the situation.

I'm like to point out that in the future, care should be taken to
_strictly_ avoid adding such dependencies between accelerated
routines, because it's a pain to keep up with such changes for non-x86
maintainers.

Guillaume
