* x86/swr: replace sse4 instructions in pack_6ch with sse onesJames Almer2014-11-06
| | | | | | | | | There's no benefit from using blendps here except on CPUs with AVX, where it's faster than shufps according to Intel's documentation. As such, rename the sse4 functions to sse/sse2 and use shufps instead. Reviewed-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: James Almer <jamrial@gmail.com>

* libswresample: move condition to start of loop.Reimar Döffinger2014-09-07
| | | | | | | | | This avoids several issue like calculating sum/maxcoef incorrectly due to adding up matrix entries that will be overwritten, as well as out-of-range writes to s->matrix if the maximum allowed number of channels is used. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
