James Almer	edff061fb0	x86/swr: add ff_float_to_int32_a_avx2 13797 decicycles in ff_float_to_int32_a_sse2, 32768 runs, 0 skips 8603 decicycles in ff_float_to_int32_a_avx2, 32766 runs, 2 skips Reviewed-by: Christophe Gisquet <christophe.gisquet@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>	10 years ago
James Almer	b385c4c6a3	x86/swr: replace sse4 instructions in pack_6ch with sse ones 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>	10 years ago

Reimar Döffinger	2c5c37ade1	libswresample: move condition to start of loop. 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.

Reimar Döffinger	284123d7fd	Remove pointless if. A branch to avoid some calculation seems unlikely to have any benefits. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Reimar Döffinger	2231d5b671	libswresample: Avoid needlessly large on-stack array. 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>	10 years ago
