exposing it may be ok, but theres not always a ResampleContext
we also support resampling through soxr (which uses a fft based
i think the patch will break that due to
invert_initial_buffer_func being NULL
also this seems to give different output with
./ffmpeg -i matrixbench_mpeg2.mpg -af asetnsamples=1,aresample=8000 -t 30 foo.wav
./ffmpeg -i matrixbench_mpeg2.mpg -af asetnsamples=1024,aresample=8000 -t 30 foo.wav
