Thanks for the report. I am relieved to say it is not my fault, it is a
bug in dynaudionorm: when it detects EOF, it calls flush_buffer(), that
in turns calls filter_frame(). Normally, it should result in the last
frames being pushed to the next filter, but in this instance is results
in dynaudionorm queuing the frame.

Seen from the outside, that means dynaudionorm->request_frame() is doing
nothing. It should either return EOF or cause a frame to be pushed.

I am afraid that is as far as I can go, I do not know the algorithm
dynaudionorm is using.
