Comment (by beafdefx):

 I don't think I understand.  The output buffer is bigger than the input
 buffer by exactly the ratio of the input sample rate to the output sample
 rate, and I'm telling the resampler I have exactly room for 16000 samples
 in each buffer.  The return value from swr_convert is exactly 16000, so I
 assume is is processing every sample in and placing every resampled sample
 out.  Am I perhaps misunderstanding the API?

 Like I mentioned before, the resampling is working perfectly in my Android
 code, empirically speaking.  There is nothing wrong with the output.  The
 internal buffers inside swresample just appear to be growing out of
 control when the output sample rate is greater than the input sample rate.
