2014-11-07x86/swr: replace sse4 instructions in pack_6ch with sse onesJames Almer
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>

2014-09-07libswresample: move condition to start of loop.Reimar Döffinger
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>
2014-09-07Remove pointless if.Reimar Döffinger
A branch to avoid some calculation seems unlikely to have any benefits. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
2014-09-07libswresample: Avoid needlessly large on-stack array.Reimar Döffinger
We only actually need to use a tiny part of it. Unfortunately we seem to have no real test coverage on the code, so this is a bit risky. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
