Hi!
I am using the Osprey 210 video capture card in an application based on DirectShow. I have tried to narrow down to a smallest possible example in this post. I can provide the complete context if necessary.
I have the following DirectShow graph that works fine:
[Osprey 210]->[AVI mux]->[File writer]
The video capture device is a Osprey 210 video capture card with the s-video input connected to a video camera. If I insert a smart tee filter into this graph it stops immediately after starting with no error message. The graph is now:
[Video capture]->[Smart tee]->[AVI mux]->[File writer]
If I insert a AVI decompressor filter before the smart tee and a compressor after the smart tee it works again. Anyone who have got an idea of what I might be doing wrong? Have I missed something obvious (or not so obvious) in this setup?
Best regards
Daniel Sundberg

The problem was fixed by replacing the smart tee with an infinite tee filter. For some reason I also had to insert a dummy filter at the end of the graph. For some reason there seemed to be a problem with the timestamps arriving to the AVI mux.
