Thanks for the detailed error message.
I have installed the FlyCapture SDK with the DirectShow filter but unfortunately without an actual device I can't test or reproduce.
From what I understand there are two possibilities:
1. The Point Grey DirectShow filter does not implement the IAMStreamConfig interface (to configure camera image size), as it is not mandatory, but Kinovea or AForge requires it while the other software you tested it with does not.
2. The DirectShow filter does implement the interface but there is a mismatch in threading model that make it impossible for Kinovea or AForge to retrieve it.
I would be interested to know how it behaves in a barebone AForge-based application outside of Kinovea context, to see where the problem lies.
You can download the SimplePlayer and the SnapshotMaker applications from here : http://www.aforgenet.com/framework/samples/video.html
Does it work in these applications?
In the SnapshotMaker, can you change video resolution?
What program does it work in?
