Can you explain this in more detail? I'd like to understand whether the issues you refer to are something which would be fixed by the ffmpeg utility allowing selection of devices for libavfilter, or whether they are something unrelated. (For library users the currently-supported way of getting the same device again is to keep a reference to the device and reuse it. If there is some case where you can't do that then it would be useful to hear about it.)
