Paul B Mahol	928061670e	libswscale: GBRAP input & output and GBRAP16 input support Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Derek Buitenhuis	33c827f632	swscale: Properly scale YUV Only shift limited range luma, and always only shift chroma for upconversion. Based off a patch by Michael Niedermayer. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Vittorio Giovara	f84a1b597c	swscale: support AV_PIX_FMT_YA16 as input Based on a long debug session with Kostya.	11 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.	11 years ago
Kostya Shishkov	5420099cab	swscale: correctly pad destination buffer in rgb conversion Bug-Id: 772 CC: libav-stable@libav.org Found-By: Justin Ruggles <justin.ruggles@gmail.com> Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago
Diego Biurrun	880e2aa236	Remove all Blackfin architecture optimizations Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.	11 years ago
Justin Ruggles	d9a542ace1	swscale: Set alpha to opaque for internal palettes. Fixes conversion of pal8 to rgb formats with alpha. Updated references for 2 FATE tests which previously encoded fully transparent images. Based on a patch by Baptiste Coudurier <baptiste.coudurier@gmail.com>	11 years ago

Michael Niedermayer	e58013dd8f	sws: use planarRgbToRgbWrapper only for 8bit per component The function doesnt support >8bit currently Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	12 years ago

Mans Rullgard	a805cefd8b	swscale: avoid pointless use of compound literals Some compilers (e.g. old gcc) have trouble with these. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Paul B Mahol	0cc1a86dc3	rgb2rgb: rgb12to15() Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	e7843db3df	swscale: fix invalid conversions and memory problems. Fixes problems where rgbToRgbWrapper() is called even though it doesn't support this particular conversion (e.g. converting from RGB444 to anything). Thirdly, fixes issues where rgbToRgbWrapper() is called for non-native endiannness conversions (e.g. RGB555BE on a LE system). Fourthly, fixes crashes when converting from e.g. monowhite to monowhite, which calls planarCopyWrapper() and overwrites/reads because n_bytes != n_pixels.	13 years ago

Janne Grunau	6e9bb5aa3e	swscale: prevent invalid writes in packed_16bpc_bswap Writes past the end of the destination buffer were occuring when its stride was smaller than the stride of the source. Fixes Bug #183.	13 years ago

John Stebbins	09d243ddd0	swscale: Fix stack alignment for SSE Although gcc guarantees 16 byte stack alignment, threads under WinXP don't appear to be guaranteed to start stack aligned. So fix the alignment. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Kostya Shishkov	42ba12888b	Do not convert RGB buffer at once when stride does not fit exact samples. When converting RGB format to RGB format with the same bits per sample, unscaled path performs conversion on the whole buffer at once. For non-multiple-of-16 BGR24 to RGB24 conversion it means that padding at the end of line will be converted too. Since it may be of arbitrary length (e.g. 8 bytes), operating on the whole buffer produces obviously wrong results. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	55eda370cb	swscale: clip unscaled colorspace conversion path. Prevents overflows on very bright scenes when adding dither, which may lead to black dots.	14 years ago
