* x86/flacdsp: add SSE2 and AVX decorrelate functionsJames Almer2014-11-13
| | | | Two to four times faster depending on instruction set, block size and channel count.
* x86/flacdsp: separate decoder and encoder dsp initializationJames Almer2014-11-12

* lavc/flacenc: add sse4 version of the 16-bit lpc encoderJames Darnley2014-08-13
| | | | | | | | | | From 1.8 to 2.4 times faster. Runtime is reduced by 2 to 39%. The speed-up generally increases with compression_level. This lpc encoder is not used with levels < 3 so it provides no speed-up in these cases. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
