2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-13Fix MMX rgb24 to yuv conversion with gcc 4.6Mans Rullgard
When built with gcc 4.6, the MMX rgb24 to yuv conversion gives wrong output. The compiler produces this warning: libswscale/swscale_template.c:1885:5: warning: use of memory input without lvalue in asm operand 4 is deprecated Changing the memory operand to a register makes it work. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-01-18Replace ASMALIGN() with .p2alignMans Rullgard
This macro has unconditionally used .p2align for a long time and serves no useful purpose.

2010-08-23swscale: fix unaligned accesses in (RGB|BGR)32_1 to YUV conversionMåns Rullgård

2010-07-18Another try at fixing swscale on win64, as per r31153.Anton Mitrofanov
Don't change paramater passing, but instead use casts. Shouldn't affect asm output on anything other than win64. libswscale should work on win64 now. The rest of ffmpeg still isn't win64 compatible due to the issue of xmm clobbers, but swscale doesn't use any SSE. Patch by Anton Mitrofanov <BugMaster AT narod DOT ru>.

2010-05-12Revert r31153. It failed to build on:Ramiro Polla
x86_64 / Mac OS X gcc 4.0.1 x86_64 / Linux icc (all) x86_64 / Linux gcc 4.0.4 x86_64 / OpenBSD gcc 3.3.5 x86_64 / Linux suncc 5.10 and there are some reports of crashes. Originally committed as revision 31170 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale
2010-05-11Use int instead of long to pass width parameters in non-public functions.Ramiro Polla
long was being incorrectly used as an x86-sized register, both for 32 and 64 bits, but this is not the case in win64. Originally committed as revision 31153 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale
2010-03-27libswscale: Relicense almost all x86 assembler optimizations as LGPL.Diego Biurrun
