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
Diego Biurrun	c2503d9c8a	swscale: ppc: Hide arch-specific initialization details Also give consistent names to init functions.	11 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
Diego Biurrun	5a6e3c039c	swscale: Mark all init functions as av_cold	13 years ago
Ronald S. Bultje	2254b559cb	swscale: make filterPos 32bit. Fixes overflows for large image sizes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Diego Biurrun	04217de4d6	swscale: K&R formatting cosmetics for PowerPC code (part I/II)	13 years ago
Diego Biurrun	33ad8c3cab	cosmetics: Remove some unnecessary block braces.	13 years ago
Ronald S. Bultje	f48b12e0a6	swscale: update altivec yuv2planeX asm to new per-plane API.	13 years ago
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	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.	14 years ago
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).	14 years ago
Mans Rullgard	635930d466	PPC: swscale: disable altivec functions for unsupported formats Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Ronald S. Bultje	97535ffb97	swscale: remove unused xInc/srcW arguments from hScale().	14 years ago
Ronald S. Bultje	ca364a5b43	swscale: extract SWS_FULL_CHR_H_INT conditional into init code.	14 years ago
Ronald S. Bultje	bda9b20fa4	swscale: un-special-case yuv2yuvX16_c(). Make yuv2yuvX16_c a function pointer for yuv2yuvX(), so that the function pointer becomes bitdepth-independent.	14 years ago
Ronald S. Bultje	075d0ae72c	swscale: enable hScale_altivec_real.	14 years ago
Ronald S. Bultje	67d80a5421	swscale: split out ppc _template.c files from main swscale.c.	14 years ago
Ronald S. Bultje	a3e9bb5dee	swscale: remove indirections in ppc/swscale_template.c.	14 years ago
Ronald S. Bultje	0e5d31b16b	swscale: split out unscaled altivec YUV converters in their own file.	14 years ago

Ronald S. Bultje	93681fbd50	swscale: fix compile on ppc.	14 years ago
