Quick reply as I don't have much time at this moment: enable the DEBUG symbol in avfilter.c and use -logleve debug, that should show you when every callback is called and understand how the filterchain processing stuff works. And thanks for the contribution. BTW if you're a student and interested we have a libavfilter GSoC task just waiting for you, or for any interested student.
