Michael Niedermayer	291d464161	swresample: fix AV_CH_LAYOUT_STEREO_DOWNMIX input Fixes Ticket 3542 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	2b58c9c945	swresample/resample_template: try to consider src_size more exactly This should avoid slight differences in the output causes by input size alignment differences between archs Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	5027f39712	swresample/resample: use av_malloc_array() where appropriate Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	a5290cb1ac	swresample/dither: use av_malloc_array() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	f9158b01d0	swresample/resample: Limit filter length Related to CID1197063 The limit choosen is arbitrary and much larger than what makes sense. It avoids the need for checking arithmetic operations with the length for overflow Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
James Almer	63dbba655e	swresample/resample: sse float linear interpolation About two times faster Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

James Almer	32291ba6ea	swresample: add swri_resample_float_sse At least two times faster than the C version. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Matt Oliver	8236747511	Automatically change MANGLE() into named inline asm operands when direct symbol reference in inline asm are not supported. This is part of the patch-set for intel C inline asm on windows support Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
James Almer	3d48cbc56c	swresample: reuse COMMON_CORE asm where possible Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
James Almer	7c8bf09edd	swresample: change COMMON_CORE_INT16 asm from SSSE3 to SSE2 pshuf+paddd is slightly faster than phaddd. The real gain is in pre-ssse3 processors like AMD K8 and K10, which get a big boost in performance compared to the mmxext version Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Reimar Döffinger	e535897fad	Fix libswresample compilation with Apple Neon assembler. Signed-off-by: Carl Eugen Hoyos <cehoyos@ag.or.at>	11 years ago
Martin Storsjö	3dd04cbcf7	swresample: Add arm&x86 clobber tests Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Reimar Döffinger	cbeaf67888	Avoid using empty macro arguments. These are not supported by all compilers (gcc 2.95 but also older SPARC compilers, see gcc bug #33304 for example), and there is no real need for them. One use of this feature remains in libavdevice/v4l2.c which can't be replaced quite as easily. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	11 years ago
Stefano Sabatini	334e2e2363	lavu,lavc,lswr: do not hardcode AV_SAMPLE_FMT_NB value when setting sample format max value The constant may change in libavutil but the library may be compiled against an older version, thus rejecting a value which is otherwise supported by the new libavutil. INT_MAX is used here to denote the max allowed value for a sample format. The opt-test code is changed to provide a valid reference example.	11 years ago
James Almer	56572787ae	Add Windows resource file support for shared libraries Originally written by James Almer <jamrial@gmail.com> With the following contributions by Timothy Gu <timothygu99@gmail.com> * Use descriptions of libraries from the pkg-config file generation function * Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser) * Use "FFmpeg" for ProductName as MSDN says "name of the product with which the file is distributed" [1]. * Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1]. * Only build the .rc files when --enable-small is not enabled.
