This removes the last use of the ff_put/add_pixels_clamped global
function pointers, and as such they are removed.
This patch has a negative effect on performance on MIPS, since there's
a SIMD-optimized put/add_pixels_clamped, but no xvid or jrev. From a
code maintenance point of view, that is probably acceptable.
Because the global function pointers are removed, this fixes the following
tsan warnings when running e.g. fate-dnxhr-parse:

ptrdiff_t is the correct type for array strides and similar.

xvididct: Ensure that the scantable permutation is always set correctly
Merged-by: Michael Niedermayer <michaelni@gmx.at>
|
|
The Xvid IDCT is not MMX-specific.
|
|
This fixes cases where the scantable permuation would get overwritten by
the general idctdsp initialization.

idct: Split off Xvid IDCT
Conflicts:
libavcodec/Makefile
libavcodec/mpeg4videodec.c
libavcodec/x86/Makefile
libavcodec/x86/idctdsp_init.c
This split is somewhat restructured leaving the xvid IDCT available
outside mpeg4 if manually selected.
The code also could not be merged unchanged as it conflicted with a
bugfix in FFmpeg
Merged-by: Michael Niedermayer <michaelni@gmx.at>

|
The Xvid IDCT is only required to decode some Xvid-encoded MPEG-4 files,
so there is no point in having it as an unconditional part of idctdsp.
