Måns Rullgård	34e52abb62	DECLARE_ALIGNED macro for TMS470 compiler This compiler supports gcc-style alignment attributes for struct, but not for global variables. For the latter, alignment can be specified with a pragma, which does not work for struct members or local variables. By using both pragma and attribute, one or the other will always take effect. Unfortunately, no means exists for aligning stack variables. Originally committed as revision 21379 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	d408b77a3a	Add an AV_PRAGMA() macro for constructing _Pragma() directives The seemingly equivalent _Pragma(AV_STRINGIFY(x)) is not accepted by some compilers. Originally committed as revision 21378 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	8a24e98d50	Make DECLARE_ALIGNED macros work with external array specifiers The macro implementation might need the name of the variable being declared for compiler-specific syntax. Moving array specifiers outside the macro invocation allows this to work. Originally committed as revision 21363 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Laurent Aimar	92c6a099ba	H264 DXVA2 implementation It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under VISTA and Windows 7). It is implemented by using AVHWAccel API. It has been tested successfully for some time in VLC using an nvidia card on Windows 7. To compile it, you need to have the system header dxva2api.h (either from microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h) The generated libavcodec.dll does not depend directly on any new lib as the necessary objects are given by the application using FFmpeg. Originally committed as revision 21353 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	5e7dfb7de1	Move COPY3_IF_LT to lavc/mathops.h This obscure macro is only used in motion_est.c so having it in lavc makes more sense. See discussion here: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2008-November/056561.html Originally committed as revision 21346 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
