Ronald S. Bultje	2ed008204d	h264: Add add_pixels4/8() to h264dsp, and remove add_pixels4 from dsputil These functions are mostly H264-specific (the only other user I can spot is bink), and this allows us to special-case some functionality for H264. Also remove the 16-bit-coeff with >8bpp versions (unused) and merge the duplicate 32-bit-coeff for >8bpp (identical). Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	e5ffffe48d	h264chroma: Remove duplicate 9/10 bit functions These functions do the same thing in 16 bit space and don't need any depth specific clipping. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Bultje	0c0828ecc5	x86: Use simple nop codes for <= sse (rather than <= mmx) The "CentaurHauls family 6 model 9 stepping 8" family of CPUs (flags: fpu vme de pse tsc msr cx8 sep mtrr pge mov pat mmx fxsr sse up rng rng_en ace ace_en) SIGILLs on long nop codes.

Ronald S. Bultje	f859678f3f	vp56: Remove clear_blocks call, and clear alpha plane U/V DC only The non-alpha and alpha-Y planes are cleared in the idct_put/add() calls. For the alpha U/V planes, we only care about the DC for entropy context prediction purposes, the rest of the data is unused. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Daniel Kang	9acd23d655	x86: dsputil: Fix h263 loop filter link error in some configurations This was caused by unconditionally referencing a conditionally compiled table. Now the code is also compiled conditionally. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Daniel Kang	7a03145ed7	x86: dsputil: int --> ptrdiff_t for ff_put_pixels16_mmxext line_size param This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago

Diego Biurrun	8837f4396a	libopencore-amrwb: Make AMR-WB ifdeffery more precise The library might provide an encoder in the future, so it's better to check for the presence of the decoder rather than just the library.

Anton Khirnov	1f8f43a5b5	error_resilience: add required headers.	12 years ago
Anton Khirnov	2c54155407	h264: deMpegEncContextize Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.

Justin Ruggles	157542ebc1	lavr: fix mixing matrix reduction when normalization is disabled In some cases when an input contributes fully to the corresponding output, other inputs may also contribute to the same output.
