> So after having done some profiling runs on ffmpeg, I think it's just
ffmpeg's processing loop causing most of the cpu use in this case, via
smaller buffers (but large enough to make malloc/free expensive) and an
accordingly larger amount of allocations.
Does increasing the buffer size fixes the issue for you?
