These are mostly about releasing the memory resources. How do you open the
video file? You may need avio_close() if you used avio_open(), or standard
file closure methods if you're handling it yourself.

Also, AFAIK you don't need keep your conversation context that long, you
can release it right after sws_scale() is done.
