Diego Biurrun	110796739a	x86: hpeldsp: Move avg_pixels8_x2_mmx() out of hpeldsp_rnd_template.c The function is only instantiated once, so there is no point in keeping it in a template file.	12 years ago

Luca Barbato	46c1917350	nut: use a define for the nut version Ease switching version in the future and make evident why that value.	12 years ago
Diego Biurrun	2d5fd7886a	bgmc: Do not mark ff_bgmc_decode_init() as av_cold The function is possibly called once per block.	12 years ago

Martin Storsjö	2cca96e670	configure: Check for getenv When targeting the "windows store application" (metro) API subset (or the windows phone API subset), the getenv function isn't available. If it is unavailable, just define getenv to NULL. The check uses check_func_headers, since the function actually might exist in the libraries, but is hidden in the headers. The fallback is in config.h since msvc can't do -D defines with parameters on the command line, and it's used both within the libraries and the frontend applications (so a libavutil internal header wouldn't be enough).

Hendrik Leppkes	20c86571cc	lavfi: let gcc realign the stack on public graph driving functions The functions which actually drive the filter graph by pushing frames through it need to ensure an aligned stack for SIMD functions. This fixes a crash in YADIF filter when using a mingw build in a MSVC application. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Diego Biurrun	a8a45dfe25	avs: Increase magic value score above file extension score This should fix misdetection of AVS files as AviSynth scripts when AviSynth support is enabled (Bugzilla #357).	12 years ago
Diego Biurrun	e0f8be6413	avformat: Add AVPROBE_SCORE_EXTENSION define and use where appropriate	12 years ago
Diego Biurrun	4d7ed3e735	build: output-example: Add avutil to ELIBS in link command output-example links against swscale, which depends on avutil. In standard configurations, by pure good luck, the libs before swscale pull in all of swscale's dependencies and linking succeeds. However, in some configurations like --disable-asm this is not the case and linking fails. Hardcode the dependency to avoid a more general Makefile refactoring.	12 years ago

Reinhard Tartler	b1ee8eec84	configure: Add basic valgrind-memcheck support With the parameter --valgrind-memcheck, the configure script sets reasonable defaults that can be overridden as explained in the documentation. The idea of using set_defaults is from Luca Barbato.	12 years ago
Reinhard Tartler	95e8ac60f8	build: normalize coverage.info Without this, lcov sometimes misses to normalize paths that contain "/./". Also, ignore uninteresting hits in system headers.	12 years ago
Reinhard Tartler	768e44d044	build: tune down the output of lcov/gcov In the default settings, both tools produce a lot of unhelpful noise.	12 years ago

Christophe Gisquet	4a7af92cc8	sbrdsp: Unroll and use integer operations This patch can be controversial, by assuming floats are IEEE-754 and particular behaviour of the FPU will get in the way. Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference). sbr_qmf_pre_shuffle_c: 115 to 76 sbr_neg_odd_64_c: 84 to 55 sbr_qmf_post_shuffle_c: 112 to 83 Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago

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.

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
