* 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>
* arm: Macroize the test for 'setend' CPU instruction supportBen Avison2014-07-21
| | | | Signed-off-by: Diego Biurrun <diego@biurrun.de>
* arm: Avoid using the 'setend' instruction on ARMv7 and newerMartin Storsjö2014-07-08
| | | | | | | | | | This instruction is deprecated on ARMv8, and it is serializing on some ARMv7 cores as well [1]. [1] http://article.gmane.org/gmane.linux.ports.arm.kernel/339293 CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* 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

* arm: Drop unnecessary ff_ name prefixes from static functionsDiego Biurrun2013-04-30

* Remove unnecessary dsputil.h #includesDiego Biurrun2013-02-26
|
* 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>
* ARM: allow runtime masking of CPU featuresMans Rullgard2012-04-22
| | | | | | | This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* H264: change weight/biweight functions to take a height argument.Ronald S. Bultje2011-10-21

* 4:4:4 H.264 decoding supportJason Garrett-Glaser2011-06-13
| | | | Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.
* 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>

* ARM: NEON H264 8x8 IDCTMåns Rullgård2010-08-05
| | | | | | Parts by David Conrad. Originally committed as revision 24706 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ARM: remove some unnecessary ifdefs, fix implicit declaration warningsMåns Rullgård2010-06-02

* 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
