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
Michael Niedermayer	700bf1fa4e	swscale/swscale_unscaled: fix ya16 input Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

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
