Paul B Mahol	928061670e	libswscale: GBRAP input & output and GBRAP16 input support Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Diego Biurrun	bb789016d4	swscale: Undeprecate sws_getContext() sws_getCachedContext is not a full replacement for the function.	10 years ago
Vittorio Giovara	f84a1b597c	swscale: support AV_PIX_FMT_YA16 as input Based on a long debug session with Kostya.	10 years ago
Vittorio Giovara	e96c3b81ca	avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8 The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.	10 years ago
Luca Barbato	3a177a9cca	swscale: Fix an undefined behaviour Prevent a division by zero down the codepath. Sample-Id: 00001721-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago

Janne Grunau	0ca0924c10	swscale: add endianness conversion for AV_PIX_FMT_BGRA64\|RGBA64	11 years ago
Jean First	1481d24c3a	RGBA64 pixel formats Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago
Vittorio Giovara	6b3ff6f91a	swscale: provide a default scaler if none is set Lanczos for general case, sinc for upscaling, Gaussian for downscaling. According to current literature these scalers should be the best quality-wise algorithms for each case. Inspired from a patch by wm4 <nfxjfg@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Janne Grunau	9cfa21c8c2	swscale: support endianness conversion for AV_PIX_FMT_XYZ12	12 years ago
Janne Grunau	c1eb3e7fec	swscale: add support for endianness only conversion Use bitfields in FormatEntry array to avoid wasting an int for each flag.	12 years ago
Diego Biurrun	2b677ffca5	swscale: Add av_cold attributes to init functions missing them	12 years ago
Martin Storsjö	d192ac3e03	swscale: Disallow conversion to GBRP16 This reverts parts of `d6d5ef5534`, that didn't work right. (The tests that were added failed on big endian, and the output looked garbled on little endian as well.) This is due to the fact that the intermediate scaling values (from e.g. hScale8To19_c or hScale16To19_c) are stored as int32_t and thus requires a separate output function, while yuv2gbrp_full_X_c only interprets it as int16_t.

Michael Niedermayer	7b41c24c5f	sws: dont enable chrSrcHSubSample for planar RGB This code path is not implemented and makes not much sense to implement either. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago
Michael Niedermayer	d6d5ef5534	sws: GBRP9, GBRP10, and GBRP16 output support Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago

Xi Wang	f73f76fd20	swscale: fix NULL checking in sws_alloc_context() sws_getCachedContext() and sws_getContext() expect sws_alloc_context() to return NULL when out of memory, as follows. if (!(context = sws_alloc_context())) return NULL; This patch fixes sws_alloc_context() to return NULL in that case.

Luca Barbato	7658295ba3	pixfmt: support more yuva formats Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Mans Rullgard	95cd815c36	swscale: try to use mmap only if available Some systems, e.g. Minix, have sys/mman.h defining MAP_ANONYMOUS without providing (working) mmap and friends. The mmx filter generation code checks only for MAP_ANONYMOUS, not for availability of mmap itself which leads to build errors on aforementioned systems. This changes the conditional compilation to use mmap only if all the required functions are available. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Luca Barbato	6d5600e855	avutil: add yuva422p and yuva444p formats	12 years ago
Anton Khirnov	0a7068fa5d	sws: do not use av_pix_fmt_descriptors directly.	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Martin Storsjö	75c37c5ace	swscale: Provide the right alignment for external mmx asm This reverts parts of `e0c6cce447`. There is external mmx asm that requires this alignment. This fixes crashes when using swscale in builds with external mmx, without inline assembly. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	12 years ago
Diego Biurrun	17337f54c0	x86: Split inline and external assembly #ifdefs	12 years ago
Mans Rullgard	c318626ce2	x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	12 years ago

Ronald S. Bultje	1254022ea7	swscale: fix filtersize clipping. if srcW<=2, clip(x, 1, srcW-2) still allows srcW to be < 1.	13 years ago
Ronald S. Bultje	dae2ce361a	swscale: enforce a minimum filtersize. At very small dimensions, this calculation could lead to zero-sized filters, which leads to uninitialized output, zero-sized allocations, loop overflows in SIMD that uses do{..}while(i++<filtersize); instead of for(i=0;i<filtersize;i++){..} and several other similar failures. Therefore, require a minimum filtersize of 1. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
