2020-05-20swscale/x86/swscale: Fix undefined left shifts of negative numbersAndreas Rheinhardt
This affected many FATE-tests: The number of failing tests went down from 663 to 344. (Both numbers exclude tests that failed because of unaligned accesses in code that is inside #if HAVE_FAST_UNALIGNED.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit 736c7c20e7819811dc59f43490563789b192eb6e)
2017-11-13Fix missing used attribute for inline assembly variablesThomas Köppe
Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2014-08-04avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara
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.
