Peter Meerwald	be6cde3ce8	lavr: fix missing " in header documentation Signed-off-by: Peter Meerwald <p.meerwald@bct-electronic.com> Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	511cf612ac	miscellaneous typo fixes	12 years ago
Justin Ruggles	b2fe6756e3	lavr: add option for dithering during sample format conversion to s16	12 years ago
Hendrik Leppkes	0cf3505930	avresample: use valid log context in mixing functions Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Justin Ruggles	f322b20735	lavr: only save/restore the mixing matrix if mixing is being done	12 years ago
Justin Ruggles	f1c2915ce1	lavr: remove automatic context close/open for resampling compensation It adds unnecessary complication for insignificant usability improvement. The user really should know if they'll need resampling compensation before opening the context. Note that only the documentation has changed. The current functionality will still work until the next major bump.	12 years ago
Justin Ruggles	230acdde26	lavr: move AudioMix struct definition to audio_mix.c	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	887d4c05c9	lavr: clarify documentation for avresample_get/set_matrix()	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	d2f9f8e094	lavr: correct the documentation for the ff_audio_resample() return value	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
Ronald S. Bultje	7a9e65acee	x86: lavr: fix stack allocation for 7 and 8 channel downmixing on x86-32 Fixes crashes on Win32 and stack overruns on x86-32 in general.	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
Diego Biurrun	2b479bcab0	build: Drop AVX assembly ifdefs An assembler able to cope with AVX instructions is now required.	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Diego Biurrun	4b60fac419	x86: PALIGNR: port to cpuflags	12 years ago
Diego Biurrun	352e18b766	x86: avresample: Add missing colons to assembly labels YASM accepts labels without colons, but NASM issues warnings.	12 years ago
Diego Biurrun	04581c8c77	x86: yasm: Use complete source path for macro helper %includes This is more consistent with the way we handle C #includes and it simplifies the build system.	12 years ago
Diego Biurrun	6860b4081d	x86: include x86inc.asm in x86util.asm This is necessary to allow refactoring some x86util macros with cpuflags.	12 years ago
Anton Khirnov	dc5793062e	lavr: document upper bound on number of output samples. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Anton Khirnov	01b760190d	lavr: add general API usage doxy Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Justin Ruggles	10e645e9cb	lavr: handle clipping in the float to s32 conversion We cannot clip to INT_MAX because that value cannot be exactly represented by a float value and ends up overflowing during conversion anyway. We need to use a slightly smaller float value, which ends up with slightly inaccurate results for samples which clip or nearly clip, but it is close enough. Using doubles as intermediates in the conversion would be more accurate, but it takes about twice as much time. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Anton Khirnov	006afc7a0b	lavr: bump major to 1 and declare it stable.	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

Tim Walker	b901c30da6	lavr/audio_mix_matrix: acknowledge the existence of LFE2. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	12 years ago

Anton Khirnov	4d7adec8bd	AVOptions: store defaults for INT64 options in int64 union member. Double does not have enough precision to represent all int64 numbers exactly.	12 years ago
