* 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. Sample program to reproduce the problem is here https://gist.github.com/2431768 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* swr: add a swr_flags AVOptionMichael Niedermayer2012-04-11
| | | | | | | Using swr_flags instead of plain flags will avoid conflicts that arise with plain flags and multiple libs (which all have AVOption flags) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
