* swresample: slightly nicer debug output for auto matrixwm42015-10-15
| | | | This is the matrix that will be used for up/downmixing.
* libswresample/rematrix: Check for malloc errorsMichael Niedermayer2015-06-04
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* swresample: Allow reinitialization without ever setting channel layoutsMichael Niedermayer2015-04-12

* swresample/x86/rematrix_init: Check av_malloc* return codes, forward errorsMichael Niedermayer2015-02-09
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* 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>
* Remove pointless if.Reimar Döffinger2014-09-07
| | | | | | A branch to avoid some calculation seems unlikely to have any benefits. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* libswresample: Avoid needlessly large on-stack array.Reimar Döffinger2014-09-07
| | | | | | | | 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>
