* swresample: Use channel count in rematrix initializationMarcin Gorzel2018-07-261-2/+2
| | | | | | | | Rematrixing supports up to 64 channels. However, there is only a limited number of channel layouts defined. Since the in/out channel count is currently obtained from the channel layout, for undefined layouts (e.g. for 9, 10, 11 channels etc.) the rematrixing fails. This patch changes rematrix init methods to use in (used) and out channel count directly instead of computing it from channel layout. Signed-off-by: Michael Niedermayer <[email protected]>
* swresample/rematrix: fix update of channel matrix if input or output layout ↵Tobias Rapp2018-02-191-2/+4
| | | | | | | | | is undefined Prefer direct in/out channel count values over channel layout, when available. Fixes a pan filter bug (ticket #6790). Signed-off-by: Tobias Rapp <[email protected]>

* libswresample: move condition to start of loop.Reimar Döffinger2014-09-071-4/+6
| | | | | | | | | 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 <[email protected]>
