Stefano Sabatini	f47a7cb777	Move read_line() and write_line() definition from pixdesc.h to pixdesc.c, which are now not anymore marked as static inline. Fix the inclusion of the private header intreadwrite.h in the public header pixdesc.h. Originally committed as revision 21854 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	a768816c33	Simplify expression as suggested by Måns Rullgård Originally committed as revision 21756 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	045b60bf9b	Make SHA digest function write digest value with AV_WN32 instead of assuming that output may be written as uint32_t since output buffer may not be aligned (and it's silly to force alignment on it) and it does not work in that case properly on some architectures. Originally committed as revision 21754 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	8e05f06912	Define missing llrint() as macro instead of inline function This fixes building on some broken systems. Originally committed as revision 21735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	80a07f6e47	Implement av_get_pix_fmt(), and deprecate avcodec_get_pix_fmt(). Originally committed as revision 21545 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	6c88973a75	Add AV_COPY32 Originally committed as revision 21524 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	788627dea6	Define av_alias if supported by compiler Originally committed as revision 21523 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4ae406856f	Add --malloc-prefix to apply a prefix to malloc, free etc This makes it easy to use a replacement allocator instead of the system default one. Originally committed as revision 21509 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	87fec35d8d	Add macro AV_JOIN() for joining two tokens into one Originally committed as revision 21482 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
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

Måns Rullgård	a3e02a8cad	Create and install libavutil/avconfig.h This file contains a safe subset of the config.h settings. Only bigendian is included for now, more can be added as need arises. Originally committed as revision 21321 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alexander Strange	f6d0390657	Add macros for 64- and 128-bit write-combining optimization to intreadwrite.h. Add x86 implementation using MMX/SSE. Originally committed as revision 21281 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Reimar Döffinger	3f37ab8e41	Make sure we do not export incorrect _NE pixformat descriptions by either including config.h if available or not defining them if it isn't. Originally committed as revision 21262 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
