Andrew Wason	e9b1d5ae5e	fix swr_convert buffering of packed audio 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>	13 years ago
