* lswr: channel_map requires input conversion.Nicolas George2012-07-17
| | | | | | | | channel_map is applied between in and postin. Without this test, if the input format is an acceptable internal format, the in->postin conversion is skipped. In the best case, it ignores channel_map, in the worst case it causes an assert failure if the number of channels is changed by the map.

* fix swr_convert buffering of packed audioAndrew Wason2012-04-21
| | | | | | | | | | | | swr_convert is not properly buffering packed input audio when the output is not large enough, and when resampling is not actually needed (same samplerate and no SWR_FLAG_RESAMPLE). buf_set() is only handling the first channel and leaving the others as-is.
