Ronald S. Bultje dc49bf1270 sws/pixfmt/pixdesc: add support for yuv420p9le/be. 2011-10-21 00:58:01 -07:00
Ronald S. Bultje 3f04ab4fcd swscale: split hScale() function pointer into h[cy]Scale(). 
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.

Ronald S. Bultje 28c1115a91 swscale: use 15-bit intermediates for 9/10-bit scaling. 2011-08-12 11:54:25 -07:00
Ronald S. Bultje 62ee0e6a97 Revert "swscale: use 15-bit intermediates for 9/10-bit scaling." 
This reverts commit ac0fb59348. It
causes valgrind errors which I'll want to investigate before
resubmitting this.

Anton Mitrofanov 142e76f105 swscale: fix crash with dithering due incorrect offset calculation. 
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.

Ronald S. Bultje 8a8d0ce208 swscale: for >8bit scaling, read in native bit-depth. 
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.
 2011-07-01 09:08:26 -07:00
Ronald S. Bultje ef1ee362b3 swscale: implement >8bit scaling support. 
This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

Ronald S. Bultje 4578435f35 swscale: Add Doxygen for hyscale_fast/hScale. 2011-06-29 01:20:34 +02:00
Ronald S. Bultje d6cc6ac6b8 swscale: Add Doxygen for yuv2planar*/yuv2packed* functions. 2011-06-28 20:18:58 +02:00
Ronald S. Bultje 13a099799e swscale: change prototypes of scaled YUV output functions. 
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.

Ronald S. Bultje 97535ffb97 swscale: remove unused xInc/srcW arguments from hScale(). 2011-06-26 14:41:44 -07:00
Michael Niedermayer 0af8a71d66 swscale: fix JPEG-range YUV scaling artifacts. 
YUV planes were marked as uint16_t, but they contained signed data.
Fixes issue 1108 and 675.

Ronald S. Bultje ea28175312 swscale: remove alp/chr/lumSrcOffset. 
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.

Ronald S. Bultje c8f487deae swscale: fix YUV420P 9/10bit support. 
Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.
