Replace FFmpeg with Libav in licence headers

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.

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.

ed040f35 02/18/2011 01:22 AM Ronald S. Bultje

Fix PPC build.

12802ec0 02/17/2011 10:35 PM Ronald S. Bultje

dsputil: move VC1-specific stuff into VC1DSPContext.

1da6ea39 02/17/2011 10:35 PM Ronald S. Bultje

VC1: transpose IDCT 8x8 coeffs while reading.

c73d99e6 02/02/2011 02:44 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.

80ba1ddb 01/31/2011 08:28 PM Justin Ruggles

Remove unneeded add bias from 3 functions.

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