* cosmetics: Fix spelling mistakesVittorio Giovara2016-05-04
| | | | Signed-off-by: Diego Biurrun <diego@biurrun.de>
* h264: Move start code search functions into separate source files.Ben Avison2014-08-04
| | | | | | This permits re-use with parsers for codecs which use similar start codes. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* aarch64: h264 idct NEON assembler optimizationsJanne Grunau2014-01-15
| | | | Ported from ARMv7 NEON.
* 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
* h264dsp: Factorize code into a new function, h264_find_start_code_candidateBen Avison2013-08-08
| | | | | | | | | | | | | | | This performs the start code search which was previously part of h264_find_frame_end() - the most CPU intensive part of the function. By itself, this results in a performance regression: Before After Mean StdDev Mean StdDev Change Overall time 2925.6 26.2 3068.5 31.7 -4.7% but this can more than be made up for by platform-optimised implementations of the function.

* h264: Integrate clear_blocks calls with IDCTRonald S. Bultje2013-04-10
| | | | | | | | | The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.

* 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>
* dsputil: Move ff_h264_idct function declarations to a separate headerDiego Biurrun2013-02-07

* x86: call most of the x86 dsp init functions under if (ARCH_X86)Janne Grunau2012-10-08
| | | | Rename the called dsp init functions to *_init_x86.

* 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>

* H.264/SVQ3: make chroma DC work the same way as luma DCJason Garrett-Glaser2011-01-15
| | | | | | | No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk
* H.264: split luma dc idct out and implement MMX/SSE2 versionsJason Garrett-Glaser2011-01-14
| | | | | | | | | | About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Move H264 dsputil functions into their own structMåns Rullgård2010-03-16
| | | | | | | | | | | This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code. Originally committed as revision 22565 to svn://svn.ffmpeg.org/ffmpeg/trunk
