Henrik Gramner	ab43beefab	x86inc: Drop SECTION_TEXT macro The .text section is already 16-byte aligned by default on all supported platforms so `SECTION_TEXT` isn't any different from `SECTION .text`. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
James Almer	d68c05380c	x86: check for AV_CPU_FLAG_AVXSLOW where useful Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Luca Barbato	0ac8ff618c	avresample: Reallocate the internal buffer to the correct size Fixes the corner case in which the internal buffer size is larger than input buffer provided and resizing it before moving the left over samples would make it write to now unallocated memory. Bug-Id: 825 CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Vittorio Giovara	1a3eb042c7	Replace av_dlog with normal av_log at trace level This applies to every library where performance is not critical.	10 years ago

Anton Khirnov	f4c444e17d	Postpone API-incompatible changes until the next bump.	10 years ago
Justin Ruggles	fbc0b86599	lavr: Do not change the sample format for mono audio This treats mono as planar internally within libavresample rather than changing the sample format. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Luca Barbato	b2d4565422	avresample: Add avresample_get_out_samples Utility function to get the upper bound on the number of samples the resampler would output.	11 years ago
Janne Grunau	449511740f	build: handle library dependencies in configure Instead of setting FFLIBS in each library Makefile configure exports FFLIBS-$library in config.mak.	11 years ago

Anton Khirnov	21d8f4da91	resample: remove an unneeded context variable	11 years ago
Anton Khirnov	ac976ed91e	lavr: allocate the resampling buffer with a positive size This fixes cases where very few input samples (fewer than needed for one output sample) are passed to lavr at the beginning. CC:libav-stable@libav.org	11 years ago

Anton Khirnov	254c95cdd1	resample: split linear into its own function	11 years ago
Anton Khirnov	be394968c8	resample: add initial padding explicitly This simplifies the code, since we do not have to deal with a possibly negative source index anymore.	11 years ago

Anton Khirnov	b9dea23766	resample: fix avresample_get_delay() return value The correct "next" input sample is not the first sample of the resampling buffer, but the center sample of the filter_length-sized block at the beginning. CC:libav-stable@libav.org	11 years ago
Diego Biurrun	01c5779f56	x86: Drop some unnecessary YASM ifdefs Dead code elimination is enough to avoid undefined references in these cases.	11 years ago
Diego Biurrun	aba70bb538	Add missing headers to make template files compile (more) standalone	11 years ago
Anton Khirnov	1db03a6864	lavr: return an error if a avresample_open() is called on an open context	11 years ago
Anton Khirnov	7e86c27b4e	lavr: add a function for checking whether AVAudioResampleContext is open	11 years ago
Tim Walker	76a75c523c	lavr: mix front center channel as indicated in the ATSC A/52 specification. When mixing 3 front channels into 2, the center channel is mixed into left and right with the center mix level, not -3dB.	11 years ago
Martin Storsjö	5bcbb516f2	arm: Add X() around all references to extern symbols Don't rely on the fact that an unprefixed label currently exists. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Janne Grunau	fe96769bed	aarch64: port neon clobber test from arm	11 years ago
Martin Storsjö	99e2012523	x86/arm: Add clobber tests to libavresample Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Anton Khirnov	cc976a75df	audio_mix: print (SKIP) instead of 0.0 for matrix columns removed along with output zeroing	11 years ago
Anton Khirnov	fc6a3ef40d	audio_mix: fix zeroing output channels in certain cases Specifically, when the corresponding input channel exists and its matrix column is all-zero (which is necessary for zeroing the output), the matrix column must be removed from the matrix. This is not done currently, so the mixing code would end up using uninitialized pointers from stack. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	11 years ago
Anton Khirnov	3d95d27376	audio_mix: initialize the data pointers to NULL This should make it easier to catch problems where some of those pointers are used uninitialized, since reading from NULL should always crash, while random numbers from stack can turn out to be valid pointers, so random memory may be silently overwritten.	11 years ago
Diego Biurrun	b83d1ee3b4	avutil: Move library version related macros to version.h This is a more sensible place for these macros.	11 years ago
