Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder.

This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_

cosmetics: rename ff_fmt_convert_init_ppc() to ff_fmt_convert_init_altivec().

It only has Altivec functions and is not compiled if Altivec is disabled.
(cherry picked from commit d21be5f15bec15933cb6360aa0159961d987f449)

vp8: ppc: fix invalid reads in altivec epel mc

The 4-tap filters should only access one row/column before the
reference block.

ppc: fix vc1 inverse transform, unbreak build

GCC 4.3 and later are more particular about signedness matching
in vector operations. The operations under if(rangered) were
missing assignments and thus had no effect.

VC1: merge idct8x8, coeff adjustments and put_pixels.

Merging these functions allows merging some loops, which makes the
results (particularly after SIMD optimizations) much faster.
(cherry picked from commit f8bed30d8b176fa030f6737765338bb4a2bcabc9)
56cbc5f1 02/18/2011 06:52 PM Ronald S. Bultje

Fix PPC build.
(cherry picked from commit ed040f35f298b39f1ddd45a133c82cb5d6d79dda)

dsputil: move VC1-specific stuff into VC1DSPContext.
(cherry picked from commit 12802ec0601c3bd7b9c7a2503518e28fd5e7d744)

VC1: transpose IDCT 8x8 coeffs while reading.
(cherry picked from commit 1da6ea39542424ddb691dc6cf08d611a4c6db247)
fe2ff6d2 02/04/2011 02:08 AM Justin Ruggles

Separate format conversion DSP functions from DSPContext.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

(cherry picked from commit c73d99e672329c8f2df290736ffc474c360ac4ae)
a8ae4e0e 02/02/2011 02:40 AM Justin Ruggles

Remove unneeded add bias from 3 functions.

DSPContext.vector_fmul_window()
DCADSPContext.lfe_fir()
SynthFilterContext.synth_filter_float()

Signed-off-by: Mans Rullgard <>
(cherry picked from commit 80ba1ddb58b5923b9f36a6acd542affc4ca722eb)
