| | | | | | | This fixes crashes in chromium on win64 on machines with AVX (crashes that apparently aren't triggered by fate). Signed-off-by: Martin Storsjö <martin@martin.st>

* h264: Get rid of unnecessary castsMartin Storsjö2013-02-20
| | | | | | | This gets rid of a number of warnings about casts discarding qualifiers from the pointer target, present since 7ebfb466a. Signed-off-by: Martin Storsjö <martin@martin.st>
* h264/svq3: Stop using draw_edgesRonald S. Bultje2013-02-19
| | | | | | | | | | | Instead, only extend edges on-demand when the motion vector actually crosses the visible decoded area using ff_emulated_edge_mc(). This changes decoding time for cathedral from 8.722sec to 8.706sec, i.e. 0.2% faster overall. More generally (VP8 uses this also), low-motion content gets significant speed improvements, whereas high-motion content tends to decode in approximately the same time.

* h264: Don't store intra pcm samples in h->mbRonald S. Bultje2013-02-19
| | | | | | | | | Instead, keep them in the bitstream buffer until we read them verbatim, this saves a memcpy() and a subsequent clearing of the target buffer. decode_cabac+decode_mb for a sample file (CAPM3_Sony_D.jsv) goes from 6121.4 to 6095.5 cycles, i.e. 26 cycles faster.

* get_bits: Return pointer to buffer that is the result of the alignmentRonald S. Bultje2013-02-19
| | | | | | | This allows more transparent mixing of get_bits and whole-byte access without having to touch get_bits internals. Signed-off-by: Martin Storsjö <martin@martin.st>
* h264: Add add_pixels4/8() to h264dsp, and remove add_pixels4 from dsputilRonald S. Bultje2013-02-19
| | | | | | | | | 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>
* h264chroma: Remove duplicate 9/10 bit functionsRonald S. Bultje2013-02-19
| | | | | | | 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>
* x86: Use simple nop codes for <= sse (rather than <= mmx)Ronald S. Bultje2013-02-19
| | | | | | | | 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. Signed-off-by: Martin Storsjö <martin@martin.st>
* vp56: Remove clear_blocks call, and clear alpha plane U/V DC onlyRonald S. Bultje2013-02-19
| | | | | | | | 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>
* x86: dsputil: Fix h263 loop filter link error in some configurationsDaniel Kang2013-02-18
| | | | | | | 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>
* x86: dsputil: int --> ptrdiff_t for ff_put_pixels16_mmxext line_size paramDaniel Kang2013-02-18
| | | | | | | 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>

* libopencore-amrwb: Make AMR-WB ifdeffery more preciseDiego Biurrun2013-02-17
| | | | | | | | 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. CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* h264: deMpegEncContextizeAnton Khirnov2013-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* lavr: fix mixing matrix reduction when normalization is disabledJustin Ruggles2013-02-12
| | | | | | | In some cases when an input contributes fully to the corresponding output, other inputs may also contribute to the same output. This is the case, for example, for the default 5.1 to stereo downmix matrix without normalization.
* lavr: fix matrix reduction for upmixing in certain casesJustin Ruggles2013-02-12
| | | | | Do not skip an output if the corresponding input contributes to other output channels.

|
* lavr: make sure that the mix function is reset even if no mixing will be doneJustin Ruggles2013-02-12
| | | | | If the matrix reduction ends up with no mixing matrix needed, we need to still reset the mix function accordingly and log the info to the user.
