* h264: do not use 422 functions for monochromeAnton Khirnov2014-01-06
| | | | | | | Fixes invalid memory access. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* Consistently use "cpu_flags" as variable/parameter name for CPU flagsDiego Biurrun2013-07-18

* Add av_cold attributes to arch-specific init functionsDiego Biurrun2013-02-05

* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* x86: mmx2 ---> mmxext in asm constructsDiego Biurrun2012-11-14
|
* Use ptrdiff_t instead of int for intra pred "stride" function parameter.Ronald S. Bultje2012-10-29
| | | | | This way, SIMD-optimized functions don't have to sign-extend their stride argument manually to be able to do pointer arithmetic.
* x86: use PRED4x4/8x8/8x8L/16x16 macros to declare intrapred prototypes.Ronald S. Bultje2012-10-29
|
* Remove usage of INIT_AVX in h264_intrapred_10bit.asm.Ronald S. Bultje2012-10-29
| | | | | | | Replace INIT_AVX by INIT_XMM avx. Port the whole file to use cpuflag based function declarations. Remove (now unused) cputype argument in function declaration macros. Change function prototypes to have mmx2 instead of mmxext as suffix, since that's required by cpuflags.
* x86: Replace checks for CPU extensions and flags by convenience macrosDiego Biurrun2012-09-08
| | | | | This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.
* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07
|
* x86: build: replace mmx2 by mmxextDiego Biurrun2012-08-03
| | | | | | | Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.
* x86: h264_intrapred: port to cpuflag macrosDiego Biurrun2012-07-05

* Add x86 assembly for some 10-bit H.264 intra predict functions.Daniel Kang2011-06-06
| | | | | | | Parts are inspired from the 8-bit H.264 predict code in Libav. Other parts ported from x264 with relicensing permission from author. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* h264: remove CONFIG_GPL from x86 intra prediction code.Ronald S. Bultje2011-06-02
| | | | | The authors permitted relicensing to LGPL a long time ago (Holger, Loren and Jason).
* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | 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>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
