Working a treat!
Is there anyway to do this without turning off hardware acceleration?
Neither Zoom nor Pan works for me now.
Edit - Wait just seen the url for the prototype... fantastic!
The latest version (URL mentioned above) may work with hardware acceleration turned on. The previous version used DirectShow to display the video (the standard windows video interface). I know of no way to make it work with hardware acceleration on, it seems to be an incompatibility between the DirectShow (aka DirectX, ActiveX) and the video drivers for your particular monitor. The best I could do, I think, is to have the software turn off acceleration whilst converting, and restoring the original state when finished.
In order to get the graphics working for pan and crop I have had to change the video output mechanism from DirectX to straight GDI. This is less efficient than using DirectX but todays generation of computers are so fast it doesn't seem to be much of a problem. A by-product of doing this should be to workaround the hardware acceleration problem.
BTW I have yet to see a machine that exhibits any performance improvement from having hardware acceleration turned on (athough I am sure that systems designed for game play do), on the other hand I have seen many that exhibit general graphic glitches when it is turned on.
Anyway it seems that you can at least use the application now. Cheers.
