| | | | | | | | Fixes crashes for extremely large resizes (several 100-fold). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org | ||
* | Revert two swscale commits. | Ronald S. Bultje | 2012-02-19 |
| | | | | | | | | | | | Revert "swscale: update context offsets after removal of AlpMmxFilter." (commit a95e3fa90b4190381b65d180eec5a4027075e2da) and Revert "swscale: Remove some write-only variables related to alpha handling." (commit 9d03cb9fc5ddf914920ab0dbe13f19a34c754966). They broke alpha handling - it's the evil inline asm that still uses that variable, so it's not truely write-only. | ||
* | swscale: make access to filter data conditional on filter type. | Ronald S. Bultje | 2012-02-17 |
| | | | | | Prevents crashes on 1-tap filter (unscaled). Also rename "bguf" argument to "vbuf", seems that was a typo. | ||
* | swscale: update context offsets after removal of AlpMmxFilter. | Ronald S. Bultje | 2012-02-17 |
| | |||
* | swscale: Remove some write-only variables related to alpha handling. | Diego Biurrun | 2012-02-14 |
| | |||
* | swscale: fix crashes in yuv2yuvX on x86-32. | Ronald S. Bultje | 2012-02-13 |
| | | | | | | They were introduced in an earlier commit that introduced use of named arguments. One cause was a typo, a second cause appears to be a bug in x264asm that I work around by not using named arguments. | ||
* | swscale: convert yuv2yuvX() to using named arguments. | Ronald S. Bultje | 2012-02-12 |
| | |||
* | swscale: rename "dstw" to "w" to prevent name collisions. | Ronald S. Bultje | 2012-02-12 |
| | | | | | "dstw" can collide with the word-version of the "dst" argument, causing all kind of weird stuff down the pipe. | ||
* | swscale: use named registers in yuv2yuv1_plane() place. | Ronald S. Bultje | 2012-02-12 |
| | | | | | Most of the function had been converted before, but I forgot this particular location. | ||
* | swscale: sign-extend integer function argument to qword on x86-64. | Ronald S. Bultje | 2012-02-08 |
| | |||
* | swscale: make yuv2yuv1 use named registers. | Ronald S. Bultje | 2012-02-07 |
| | |||
* | swscale: fix V plane memory location in bilinear/unscaled RGB/YUYV case. | Ronald S. Bultje | 2012-02-07 |
| | | | | | | Fixes bug 221. CC: libav-stable@libav.org | ||
* | win64: add a XMM clobber test configure option. | Ronald S. Bultje | 2012-02-02 |
| | | | | | | | This will be useful to test more aggressively for failures to mark XMM registers as clobbered in Win64 builds, and prevent regressions thereof. Based on a patch by Ramiro Polla <ramiro.polla@gmail.com> | ||
* | swscale: implement MMX, SSE2 and AVX functions for RGB32 input. | Ronald S. Bultje | 2012-02-01 |
| | |||
* | swscale: enable dithering in MMX functions. | Ronald S. Bultje | 2012-02-01 |
| | | | | | | This was accidently disabled. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> | ||
* | swscale: make rgb24 function macros slightly smaller. | Ronald S. Bultje | 2012-02-01 |
| | |||
* | swscale: convert rgb/bgr24ToY/UV_mmx functions from inline asm to yasm. | Ronald S. Bultje | 2012-01-27 |
| | | | | Also implement sse2/ssse3/avx versions. | ||
* | config.asm: change %ifdef directives to %if directives. | Ronald S. Bultje | 2012-01-27 |
| | | | | This allows combining multiple conditionals in a single statement. | ||
* | swscale: change yuv2yuvX code to use cpuflag(). | Ronald S. Bultje | 2012-01-13 |
| | |||
* | swscale: fix crash in fast_bilinear code when compiled with -mred-zone. | Ronald S. Bultje | 2012-01-10 |
| | | | | | | | Additional comments from Måns Rullgard have been integrated by Reinhard Tartler. Signed-off-by: Reinhard Tartler <siretart@tauware.de> | ||
* | swscale: specify register type. | Oka Motofumi | 2012-01-10 |
| | | | | | | Fixes a compilation failure on win64. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> | ||
* | swscale: convert yuy2/uyvy/nv12/nv21ToY/UV from inline asm to yasm. | Ronald S. Bultje | 2012-01-08 |
| | | | | Also implement SSE2/AVX variants. | ||
* | swscale: split scale.asm. | Ronald S. Bultje | 2012-01-03 |
| | | | | | scale.asm keeps horizontal scaling functions, whereas output.asm gets the vertical scaling/output functions. | ||
* | swscale_mmx: drop no longer required parameters from VSCALEX macros | Diego Biurrun | 2011-12-14 |
| | |||
* | swscale: Mark yuv2planeX_8_mmx as MMX2; it contains MMX2 instructions. | Diego Biurrun | 2011-12-14 |
| | |||
* | Remove extraneous semicolons | Mans Rullgard | 2011-12-11 |
| | | | | | | These semicolons cause invalid empty top-level declarations. Signed-off-by: Mans Rullgard <mans@mansr.com> | ||
* | swscale: handle unaligned buffers in yuv2plane1 | Ronald S. Bultje | 2011-11-13 |
| | | | | | | | The issue had been introduced in c435653627529e22d74214c2266f571255e404d6 Signed-off-by: Luca Barbato <lu_zero@gentoo.org> | ||
* | swscale: write yuv2plane1 MMX/SSE2/SSE4/AVX functions. | Ronald S. Bultje | 2011-11-05 |
| | |||
* | swscale: add missing colons to x86 assembly yuv2planeX. | Ronald S. Bultje | 2011-10-23 |
| | | | | This fixes assembling using "nasm". | ||
* | swscale: make yuv2yuvX_10_sse2/avx 8/9/16-bits aware. | Ronald S. Bultje | 2011-10-22 |
| | | | | Also implement MMX/MMX2 versions and SSE4 versions. | ||

* | Split out yuv2yuv1 luma and chroma in order to make them generic DSP functions | Kieran Kunhya | 2011-10-22 |
| | | | | Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> | ||
* | swscale: use aligned move for storage into temporary buffer. | Ronald S. Bultje | 2011-10-11 |
| | | | | The intermediate buffer is always aligned. | ||
* | sws: implement MMX/SSE2/SSSE3/SSE4 versions for horizontal scaling. | Ronald S. Bultje | 2011-09-13 |
| | | | | | | Speed: from 3.9x to 9.6x speed improvement over C, and some small (up to 15%) speed improvements over existing MMX code (particularly for bigger filters). | ||
* | swscale: split hScale() function pointer into h[cy]Scale(). | Ronald S. Bultje | 2011-08-17 |
| | | | | | | This allows using more specific implementations for chroma/luma, e.g. we can make assumptions on filterSize being constant, thus avoiding that test at runtime. | ||
* | swscale: use 15-bit intermediates for 9/10-bit scaling. | Ronald S. Bultje | 2011-08-12 |
| | |||
* | swscale: rename uv_off/uv_off2 to uv_off_px/byte. | Ronald S. Bultje | 2011-07-08 |
| | |||
* | swscale: error dithering for 16/9/10-bit to 8-bit. | Ronald S. Bultje | 2011-07-08 |
| | | | | Based on a somewhat similar idea in FFmpeg's swscale copy. | ||
* | swscale: fix 16-bit scaling when output is 8-bits. | Ronald S. Bultje | 2011-07-08 |
| | | | | | We would use the second half of the U plane buffer, rather than the V plane buffer, to output the V plane pixels. | ||
* | swscale: for >8bit scaling, read in native bit-depth. | Ronald S. Bultje | 2011-07-01 |
| | | | | | | For 9/10bit, it means we don't have to upscale to 16bit before actual scaling or pixel format conversion, and thus a performance gain. | ||
* | swscale: implement >8bit scaling support. | Ronald S. Bultje | 2011-06-29 |
| | | | | | | This means that precision is retained when scaling between sample formats with >8 bits per component (48bit RGB, 16bit grayscale, 9/10/16bit YUV). | ||
* | swscale: change prototypes of scaled YUV output functions. | Ronald S. Bultje | 2011-06-27 |
| | | | | | | | | Remove unused variables "flags" and "dstFormat" in yuv2packed1, merge source rows per plane for yuv2packed[12], and make every source argument int16_t (some where invalidly set to uint16_t). This prevents stack pollution and is part of the Great Evil Plan to simplify swscale. | ||
* | swscale: don't use planar output functions to write to NV12/21. | Ronald S. Bultje | 2011-06-27 |
| | | | | | This prevents a crash when converting to NV12/21 without the bitexact flags enabled. | ||
* | swscale: remove unused xInc/srcW arguments from hScale(). | Ronald S. Bultje | 2011-06-26 |
| | |||
* | swscale: Remove HAVE_MMX from files that are only compiled with MMX enabled. | Diego Biurrun | 2011-06-15 |
