Fixes overflows for large image sizes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2012-02-20Revert two swscale commits.Ronald S. Bultje
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.

2012-02-09pixdesc: mark pseudopaletted formats with a special flag.Anton Khirnov
This makes it possible to dintinguish them from PAL8. Fixes an invalid write in avpicture_layout().
2012-02-08Remove Sun medialib glue code.Diego Biurrun
It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.

Fixes PAL8 to YUV conversion.

2011-11-25swscale: fix failing fate tests.Ronald S. Bultje
isGray() is left as a FIXME for later.

2011-08-18swscale: split hScale() function pointer into h[cy]Scale().Ronald S. Bultje
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.
2011-08-12swscale: use 15-bit intermediates for 9/10-bit scaling.Ronald S. Bultje
2011-08-02Revert "swscale: use 15-bit intermediates for 9/10-bit scaling."Ronald S. Bultje
This reverts commit ac0fb5934893be554a44d2a1eb7a3bc7bf39da4a. It causes valgrind errors which I'll want to investigate before resubmitting this.

2011-07-11swscale: fix crash with dithering due incorrect offset calculation.Anton Mitrofanov
ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte aligned and thus at a different offset than intended. Forcing 8-byte alignment forces equal offset of dither16/32 on x86-32 and x86-64. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

Based on a somewhat similar idea in FFmpeg's swscale copy.

2011-07-01swscale: for >8bit scaling, read in native bit-depth.Ronald S. Bultje
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.
2011-06-29swscale: implement >8bit scaling support.Ronald S. Bultje
This means that precision is retained when scaling between sample formats with >8 bits per component (48bit RGB, 16bit grayscale, 9/10/16bit YUV).
2011-06-29swscale: Add Doxygen for hyscale_fast/hScale.Ronald S. Bultje
2011-06-28swscale: Add Doxygen for yuv2planar*/yuv2packed* functions.Ronald S. Bultje
2011-06-28swscale: change prototypes of scaled YUV output functions.Ronald S. Bultje
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.
2011-06-27swscale: remove unused xInc/srcW arguments from hScale().Ronald S. Bultje
2011-06-14swscale: fix JPEG-range YUV scaling artifacts.Michael Niedermayer
YUV planes were marked as uint16_t, but they contained signed data. Fixes issue 1108 and 675. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-06-10libavutil/swscale: YUV444P10/YUV444P9 support.Ronald S. Bultje

2011-06-07swscale: remove alp/chr/lumSrcOffset.Ronald S. Bultje
They are hacks added to reuse the same scaling function for different formats and they may cause problems when SIMD implementation of the same functions are used along with pure C functions.
2011-06-03swscale: split swscale.c in unscaled and generic conversion routines.Ronald S. Bultje
This duplicates the function fillPlane().
