 Replying to [comment:11 kainz]:
 > 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?
