Hello, I've seen the commit about the option for dumping the filtergraph and that reminded me about something that I'd be willing to contribute in case anybody likes it.
A while ago I was looking for a way to get information about the filtergraphs that ffmpeg builds at runtime, the individual formats that have been negotiated between input and output pins and which filters have a hardware context. I had expected that this is what the graph2dot is intended to do, but that wasn't the case. Turning a filter string into a graph is not what I was looking for. Eventually I have implemented a feature that iterates all filters, their connections and the negotiated media formats during runtime and writes them out as json or xml (using the same methods that ffprobe uses). I have attached an example output and an image as an example for what could be done with the output. Let me know whether there's some interest in this.
