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.

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

Justin Ruggles	b2eea615c0	lavr: allow setting internal_sample_fmt option by string	12 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
Justin Ruggles	a3735bb92a	lavr: cosmetics: reindent	12 years ago
Justin Ruggles	1647da89dd	lavr: make sure that the mix function is reset even if no mixing will be done If the matrix reduction ends up with no mixing matrix needed, we need to still reset the mix function accordingly and log the info to the user.	12 years ago
Justin Ruggles	646831e697	lavr: print out the mix matrix in ff_audio_mix_set_matrix() This will print the new matrix if it is set after initialization.	12 years ago
Justin Ruggles	b90632d596	lavr: always reset mix function names and pointers in mix_function_init() CC: libav-stable@libav.org	12 years ago
Justin Ruggles	f07ef2d9c9	lavr: call mix_function_init() in ff_audio_mix_set_matrix() This is needed if a custom matrix is set by the user after opening the AVAudioResampleContext because the matrix channel count can change if different mixing coefficients are used.

Justin Ruggles	a6a3164b13	x86: lavr: add SSE2/AVX dither_int_to_float()	12 years ago
Justin Ruggles	7ff3fd7ae4	lavr: log channel conversion description for any-to-any functions	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	4164b0e8d3	lavr: mix: reduce the mixing matrix when possible If the matrix results in an output channel not getting a contribution from any input channel and the corresponding input channel does not contribute to any outputs, we can skip the channel during mixing and silence it after mixing. If the matrix results in an input channel not contributing to any output channels and it is not in the output mix, or if the input channel only contributes fully to the same output channel, we can skip the channel during mixing. If the matrix results in an output channel only getting full contribution from the corresponding input channel and that input channel does not contribute to any other output channels, we can skip the channel during mixing.	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
