Janne Grunau	a24a252709	aarch64: NEON optimized FIR audio resampling Optimized for the default filter length 16. 30% faster opus silk decoding.	11 years ago
Janne Grunau	cae8df7875	lavr: define ResampleContext in resample.h Required for arch optimized resampling.	11 years ago
Anton Khirnov	21d8f4da91	resample: remove an unneeded context variable	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	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
Thilo Borgmann	d814a839ac	Reinstate proper FFmpeg license for all files.	11 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	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	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
Martin Storsjö	1d9c2dc89a	Don't include common.h from avutil.h Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	3aa696e883	avresample: De-doxygenize some comments where Doxygen is not appropriate	12 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	372647aed0	lavr: resampling: add filter type and Kaiser window beta to AVOptions	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
