Christophe Gisquet	5a97469a4f	x86: sbrdsp: Implement SSE2 qmf_deint_bfly Sandybridge: 47 cycles Having a loop counter is a 7 cycle gain. Unrolling is another 7 cycle gain. Working in reverse scan is another 6 cycles. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Martin Storsjö	769d921f3e	compat: msvc: Make sure the object files are included when linking statically If building libav with -MD in the cflags (for making the MSVC compiler generate code for using a dynamically linked libc), the system headers that declare strtod, snprintf and vsnprintf declare the functions as imported from a DLL. To hook up wrappers of our own for these functions, the function names are defined to avpriv_*, so that the calling code within libav calls the wrappers instead. Since these functions are declared to be imported from DLLs, the calling code expects to load them from DLL import function pointers (creating references to _imp__avpriv_strtod instead of directly to avpriv_strtod). If the libav libraries are not built as DLLs, no such function pointers (as the calling code expects) are created. The linker can fix this up automatically in some cases (producing warnings LNK4217 and LNK4049), if the object files are already included. By telling the linker to try to include those symbols (without the _imp prefix as the calling code ends up using), we get the object files included, so that the linker can do the automatic fixup. This is done via config.h, so that all (or at least most) of the object files in our libraries force including the compat files, to make sure they are included regardless of what files from our static libraries actually are included.

Luca Barbato	af4cc2605c	id3v2: check for end of file while unescaping tags Prevent a serious out of buffer bound write. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago
Anton Khirnov	76d23f4031	avconv: do not send non-monotonous DTS to the muxers. Hack partially based on a commit by Michael Niedermayer <michaelni@gmx.at> Should fix (or work around) bug 458.	12 years ago
Anton Khirnov	b4a5a29227	avconv: improve -re implementation Integrate the code in the packet reading function, instead of inserting sleeps in many places. This is simpler to follow and should work better.	12 years ago
Anton Khirnov	e3b225a4fe	matroskaenc: add an option to put the index at the start of the file	12 years ago
Anton Khirnov	0574bc06d2	matroskaenc: cosmetics, reorder the #includes	12 years ago

Christophe Gisquet	566b7a20fd	x86: float dsp: butterflies_float SSE 97c -> 49c Some codecs could benefit from more unrolling, but AAC doesn't.	12 years ago
Anton Khirnov	b333f3a22a	lavf-regression: use -frames instead of -t for image tests -t 0.5 is 12.5 frames at 25 fps, which may round to either 12 or 13 on different platforms.	12 years ago
Anton Khirnov	803d21f38b	lavc: schedule AVCodecContext.lowres for removal on next bump. It has been deprecated some time ago, but was forgotten during the last bump.	12 years ago
Martin Storsjö	ffb068ce8e	configure: Don't do enable_deep_weak on disabled variables This avoids cases where configure tries to weakly enable an item which actually is disabled, ending up still enabling dependencies of the item which itself is only enabled weakly. More concretely, the h264 decoder suggests error resilience, which is then enabled weakly (unless manually disabled). Previously, dsputil, which is a dependency of error resilience, was enabled even if error resilience wasn't enabled in the end. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	4d810ad2e9	configure: Use a different variable name in push/popvar The variable name 'var' is commonly used to iterate through arguments in other functions. When the pushvar function internally uses the variable 'var', it makes pushing/popping the variable 'var' not work as intended. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Diego Biurrun	9328062321	x86: dsputil: Move avg_pixels16_mmx() out of rnd_template.c The function does not do any rounding, so there is no point in keeping it in a round template file.	12 years ago
Diego Biurrun	9c112a6158	x86: dsputil: Move avg_pixels8_mmx() out of rnd_template.c The function is only instantiated once, so there is no point in keeping it in a template file.	12 years ago
Diego Biurrun	9b3a04d306	x86: Move duplicated put_pixels{8\|16}_mmx functions into their own file	12 years ago

Diego Biurrun	a053dbfcfb	ppc: Move AltiVec utility headers out of AltiVec ifdefs Now that the headers themselves have ifdef protection this is no longer necessary and more consistent with normal include handling.	12 years ago
Diego Biurrun	f5eecee865	ppc: util_altivec: Surround AltiVec-related code by appropriate ifdefs This prevents non-AltiVec-enabled compilers from choking.	12 years ago

Diego Biurrun	643e433bf7	mpegaudiosp: More consistent names for ppc/x86 optimization files	12 years ago
Anton Khirnov	8cd472d3f9	avconv: make output -ss insert trim/atrim filters. This makes output -ss sample-accurate for audio and will allow further simplication in the future.	12 years ago
Anton Khirnov	a83c0da539	avconv: make -t insert trim/atrim filters. This makes -t sample-accurate for audio and will allow further simplication in the future. Most of the FATE changes are due to audio now being sample accurate. In some cases a video frame was incorrectly passed with the old code, while its was over the limit.	12 years ago
Anton Khirnov	3d62442008	avconv_opt: allocate an OutputFile before the streams. This way OutputFile variables like recording time can be used when creating the streams.	12 years ago

Anton Khirnov	e036bb7899	lavc: clear AVBuffers on decoded frames if refcounted_frames is not set Otherwise some code might mistakenly think it is allowed to unref those buffers, which would lead to double unref.	12 years ago
