GDI overlay using DTVViewer

[Martin Whipp]

Just wondering if this is even possible. I'm currently trying to modify the
DTVViewer demo and encorperate overlays using the bitmap mixer demo.

I'm a noob to DBA and DirectShow, so any recomendations on where to start /
look would be greatly appreciated.

Many thanks,
Whipster.

Would the best approach be to add a frameGrabber filter to the graph, then
create a Memory DC and use selectObject() on a BITMAP?

that way I could use the HDC to perform GDI operations on the bitmap in memory
and use copyMemory to place the bitmap over the desired pixels?

sorry I'm getting a little stuck here, I apologise if this is way too easy,
just hoping to find out if someone out there has managed this, or has a good
idea of how to accomplish it.
