Thilo Borgmann	d814a839ac	Reinstate proper FFmpeg license for all files.	12 years ago
Justin Ruggles	074a00d192	lavr: add a public function for setting a custom channel map This allows reordering, duplication, and silencing of input channels.	12 years ago
Justin Ruggles	4d68269d58	lavr: typedef internal structs in internal.h Simplifies header dependencies by not including all other internal headers in internal.h.	12 years ago
Justin Ruggles	b2fe6756e3	lavr: add option for dithering during sample format conversion to s16	12 years ago
Justin Ruggles	42b5688d5e	lavr: fix segfault due to overlooked change needed in `14758e3` Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Justin Ruggles	14758e3211	lavr: temporarily store custom matrix in AVAudioResampleContext This allows AudioMix to be treated the same way as other conversion contexts and removes the requirement to allocate it at the same time as the AVAudioResampleContext. The current matrix get/set functions are split between the public interface and AudioMix private functions.	12 years ago
Justin Ruggles	1d86aa8b0f	lavr: do not pass consumed samples as a parameter to ff_audio_resample() Since the resampler handles buffering of unconsumed samples internally, the caller does not need this information.	12 years ago
Justin Ruggles	7f534d11ed	lavr: do not pass sample count as a parameter to ff_audio_convert() It will always be the number of samples in the input buffer, so just use that directly instead of passing it as a separate parameter.	12 years ago
Justin Ruggles	02738792c5	lavr: fix the decision for writing directly to the output buffer If there are any samples remaining in the output fifo from previous conversion calls, we have to output those samples first instead of doing direct output of the current samples.	12 years ago
Anton Khirnov	e7ba5b1de0	lavr: change the type of the data buffers to uint8_t**. This is more consistent with what the rest of Libav does. This breaks API.	12 years ago
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	8821ae649e	lavr: fix handling of custom mix matrices Adds some validation for changing parameters after setting the matrix and fixes a bug in the conversion path setup.	13 years ago
Justin Ruggles	2f096bb10e	lavr: add x86-optimized mixing functions Adds optimized functions for mixing 3 through 8 input channels to 1 and 2 output channels in fltp or s16p format with flt coeffs.	13 years ago
Justin Ruggles	6410397600	lavr: resampling: add support for s32p, fltp, and dblp internal sample formats Based partially on implementation by Michael Niedermayer <michaelni@gmx.at> in libswresample in FFmpeg. See commits: `7f1ae79d38` `24ab1abfb6`	13 years ago
Justin Ruggles	8ca08066fc	lavr: Use AV_SAMPLE_FMT_NONE to auto-select the internal sample format Also make this the default value.	13 years ago
Anton Khirnov	9684341346	lavr: do not try to copy to uninitialized output audio data. This would happen at least when lavr is used as a fifo with no conversion.	13 years ago
Anton Khirnov	0982b0a431	lavr: make avresample_read() with NULL output discard samples.	13 years ago
Justin Ruggles	c8af852b97	Add libavresample This is a new library for audio sample format, channel layout, and sample rate conversion.	13 years ago
