[FFmpeg-devel] Output to text file from filter

I want to put BBC R&D's shot change detector into FFmpeg as a filter.
but, I need to know the frame number of the frames that were picked.

I'm not sure that just outputting to the log output is right for that, 
so I'm thinking I should output to a "sidecar" file.

I've had a look, but I haven't found examples of that in FFmpeg. Does 
anyone have a pointer to a file I can reference to ensure I do it the 
FFmpeg way? Or suggest why I'm a mad-man?
