* vorbisdec: Add missing checksLuca Barbato2013-02-25
| | | | | Rate and order must not be 0 even if the specification does not say that explicitly.
* vorbisdec: cosmeticsLuca Barbato2013-02-25
| | | | Use the commonly used "if (!var)" instead of "if (var == 0)".
* vorbisdec: Error on bark_map_size equal to 0.Michael Niedermayer2013-02-25
| | | | | | | | | | | | | | The value is used to calculate output LSP curve and a division by zero and out of array accesses would occur. CVE-2013-0894 CC: libav-stable@libav.org Reported-by: Dale Curtis <dalecurtis@chromium.org> Found-by: inferno@chromium.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* lavr: Add "resample_cutoff" option as a duplicate of "cutoff"Justin Ruggles2013-02-23
| | | | | Avoids an option name conflict with libavcodec, which is needed in order to work properly with avconv.

| | | | | | | Damaged frames can lead to a mismatch, which can cause a segfault due to using an incorrect channel mapping. CC:libav-stable@libav.org

* doc: developer: Allow tabs in the vim configuration for Automake filesDiego Biurrun2013-02-23
| | | | | While we do not use Automake in libav, this allows our config to be used more globally without introducing unwanted breakage.
* Remove pointless av_cold attributes in header filesDiego Biurrun2013-02-23
| | | | | | The init functions marked as av_cold have to be executed in any case, so there is no gain from trying to mark paths leading to such functions as unlikely.

* libx264: change i_qfactor to use x264cli's defaultJohn Van Sickle2013-02-23
| | | | | | | | This also allows libx264 to modify its i_qfactor value when using the "-tune" setting. Previously it had a static value of 1.25 Signed-off-by: Anton Khirnov <anton@khirnov.net>

* x86: h264: Don't use redzone in AVX h264_deblock on Win64Matt Wolenetz2013-02-21
| | | | | | | 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. Signed-off-by: Martin Storsjö <martin@martin.st>
* 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. Signed-off-by: Martin Storsjö <martin@martin.st>
* 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>
