Michael Niedermayer	328ea6a9a5	swscale: Add input support for 12-bit formats Implemented for AV_PIX_FMT_GBRP12. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	8 years ago
Luca Barbato	2b5b1e1e9b	swscale: Rename is9_OR_10 to match what it does It is used to select functions that work with 9-15bits.	8 years ago
Ronald S. Bultje	70d418c7e6	Revert "PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD." This reverts commit 1df908f33f658979b32599489ca6f1a39821013c. The expected performance improvements are essentially non-existent.	9 years ago
Dan Parrot	1df908f33f	PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD. This patch addresses Trac ticket #5570. The optimized functions are in file libswscale/ppc/input_vsx.c. Each optimized function name is a concatenation of the corresponding name in libswscale/input.c with suffix _vsx.

Rong Yan	2af180bf1b	swscale/ppc/yuv2rgb_altivec: POWER LE support in the macros vec_unh() and vec_unl() Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Luca Barbato	da60b99a88	ppc: Restrict some Altivec implementations to Big Endian In Little Endian the vec_ld/vec_st operations work as expected only for byte-vectors.	10 years ago
Rong Yan	603c839398	swscale/ppc/swscale_altivec.c: POWER LE support in yuv2planeX_8() delete macro GET_VF() it was wrong GCC tool had a bug of PPC intrinsic interpret, which has been fixed in GCC 4.9.1. This bug lead to errors in two of our previous patches. We found this when we update our GCC tools to 4.9.1 and by reading the related info on GCC website. We fix our previous error in two separate commits Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Christophe Gisquet	5d38c628b0	ppc: libswscale: use LOCAL_ALIGNED instead of DECLARE_ALIGNED The later may yield incorrect code for on-stack variables. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Mans Rullgard	07eb7e20af	ppc: swscale: rework yuv2planeX_altivec() This gets rid of the variable-length scratch buffer by filtering 16 pixels at a time and writing directly to the destination. The extra loads this requires to load the source values are compensated by not doing a round-trip to memory before shifting. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Pavel Koshevoy	665100c2f1	Fix destination row striding in altivec_yuv2_bgr24. Misaligned row artifacts showed up when a 624x352 frame was converted to BGR24 format. When advancing to the next row the destination linesize was added to the last output pointer position which was not linesize aligned, resulting in a distorted picture.

Kieran Kunhya	ff7913aef1	Split up yuv2yuvX functions Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Mans Rullgard	d853e571ad	ppc: fix some pointer to integer casts Use uintptr_t instead of plain int. Without this change, the comparisons will come out wrong for pointers in certain ranges. Fixes random failures on ppc64. Also fixes some compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
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.	14 years ago
Luca Barbato	3304a1e69a	swscale: add dithering to yuv2yuvX_altivec_real It just does that part in scalar form, I doubt using a vector store over 2 array would speed it up particularly. The function should be written to not use a scratch buffer.	14 years ago
Ronald S. Bultje	28c1115a91	swscale: use 15-bit intermediates for 9/10-bit scaling.	14 years ago
Ronald S. Bultje	948ccdadf4	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.	14 years ago

Ronald S. Bultje	45f6ffe5e9	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).	14 years ago

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.	14 years ago
Ronald S. Bultje	dc179ec819	swscale: split yuv2packedX_altivec in smaller functions. This will likely lead to a considerable performance boost, since it removes a branch from the inner loop. Part of the Great Evil Plan to simplify swscale.	14 years ago
