Any suggestions as to where to look for the source of the problem?

So far I have followed through gdb that the demux_mf seems to be opening 
and reading the files successfully. At that point I seems to be stuck. 
The output results seem to indicate that either the output processor is 
not getting to the next frame or or the new input frame is not being 
read into the right place.
