* dsputil: cosmetics: Lose camelCase on ff_cropTbl and ff_squareTbl namesDiego Biurrun2014-03-13
| | | | Also switch from "tbl" to "tab" name suffixes.
* 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

* h264pred: Add a few missing const declarations for ff_cropTbl derived pointersMartin Storsjö2013-04-08
| | | | | | | | The pointers that get assigned ff_cropTbl were made const in 9e0f14f1, but other variables that transitively are assigned based on these variables were missed. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavc: Make pointers to ff_cropTbl constMartin Storsjö2013-04-08
| | | | | | There's no point in these pointers not being const. Signed-off-by: Martin Storsjö <martin@martin.st>

* 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.

* 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: 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>
