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.	2012-07-27 11:25:48 -04:00
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`	2012-07-08 15:22:11 -04:00

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.	2012-05-09 17:38:23 +02:00
