Sorry :). After my last rather unsuccessful effort at getting video and openGL to work in C# (http://forums.overclockers.co.uk/showthread.php?t=17708445) I'm back again.

Would it be possible for any of you to see if this works:

http://www.ollywoodman.tsohost.co.uk/Debug.zip

Just unzip it and try and run Test1.exe and Test2.exe. Requires .Net 2.0.

You should hopefully see a black screen with a drop down menu and a load video button at the bottom. Try loading some videos (2 small avi files are in the zip if you dont have any). If you have any video sources (i.e: webcams) attached you should be able to load them using the drop down menu. You should hopefully see these sources being rendered onto slowly spinning squares, like this:

Picture1.jpg


If it works could you let me know:
> What cameras + file types it worked for?
> What fps you got. Was the fps different in the 2 exes?
> What graphics card + processor you have

Thanks
 
getting an unhandled exception and missing glfw.dll error. also cpu load is at 100% and i can't close it gracefully. i just have to wait for windows to shut it as "not responding".

x1950pro, cat 7.2s, vista. :p
 
Thanks. Thats just an issue where I assumed people would already have a dll when actually people dont. I've managed to recreate the problem. To fix it just download the dll and stick it in the directory with everything else:

http://www.ollywoodman.tsohost.co.uk/glfw.dll

What about after you do that?

(this is fixed in the zip file for anyone new downloading)
 
Hi,

When using test1 I recieve the following error:

See the end of this message for details on invoking

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Ta. What graphics card are you using? The error is because your card doesn't support openGl 2 (I believe).
 
Both of them seem quite unresponsive to start with until opening the webcam/video.

Test1.exe - 20-30 FPS
Test2.exe - 50-60 FPS

Test them both with the 2 avi files provided and my Sony EyeToy webcam.

Windows XP Pro SP2
AMD Athlon 64 3000+ Venice
BFG GeForce 7800 GT OC

The unresponsiveness is probably due to poor coding on some of the bits I'm not trying to test. Good to hear that it works. Would it be possible for you to test what FPS you get on Test2 if you force vsync off in your graphics card settings? I get over 1000fps, so I'm guessing your fps is vsync limited?

Thanks for the help.
