Anton Khirnov	f4c444e17d	Postpone API-incompatible changes until the next bump.	11 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>	11 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
Janne Grunau	a24a252709	aarch64: NEON optimized FIR audio resampling Optimized for the default filter length 16. 30% faster opus silk decoding.	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	f7c5fd8151	resample: implement flushing	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	eed752d61d	resample: drop useless abs() negative sample_index is handled in the block above.	11 years ago
Anton Khirnov	3c84f6b5d2	resample: reindent	11 years ago
Anton Khirnov	f20892eb67	resample: split the nearest neighbour path into a separate function pointer	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

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
James Almer	22ef9cb46d	avresample: Include libavutil/avutil.h in version.h Should fix issues compiling lavr's Windows resource file. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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.

Diego Biurrun	8f8bc92365	Add missing #includes for INT64_MAX and INT64_C	11 years ago
Justin Ruggles	211ca69b13	lavr: check that current_buffer is not NULL before using it Fixes a segfault during resampling when compiled with -DDEBUG. Fixes all fate-lavr-resample tests with -DDEBUG. CC:libav-stable@libav.org	11 years ago
Derek Buitenhuis	206895708e	x86inc: Remove our FMA4 support This is so we can sync to x264's version of FMA4 support. This partialy reverts commit `79687079a9`. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Derek Buitenhuis	15748773bf	avresample/x86: Switch operand order for mulps With the forthcoming VEX instruction emulation, mulps must have only the third operand point to memory, as this is what vmulps expects. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Anton Khirnov	df6737a55f	audio_mix: fix channel order in mix_1_to_2_fltp_flt_c CC:libav-stable@libav.org	11 years ago

Justin Ruggles	50f4337a2f	lavr: Add "resample_cutoff" option as a duplicate of "cutoff" Avoids an option name conflict with libavcodec, which is needed in order to work properly with avconv.	12 years ago
Justin Ruggles	157542ebc1	lavr: fix mixing matrix reduction when normalization is disabled In some cases when an input contributes fully to the corresponding output, other inputs may also contribute to the same output. This is the case, for example, for the default 5.1 to stereo downmix matrix without normalization.	12 years ago
Justin Ruggles	600b4c973f	lavr: fix matrix reduction for upmixing in certain cases Do not skip an output if the corresponding input contributes to other output channels.	12 years ago
