Web Camera not Working

Hello,

I'm having issues with a webcam on a Dell Windows Latitude 7230 tablet.

The first video mode in the list works but none of the other video modes do.

I did check per your instructions if TRVWebCam.SampleCB is being called and it seems that it is NOT being called.

What does that mean if it is not being called? What are the next steps I should take to get this web camera working at a higher resolution?

Thanks!

Drew

Please do additional testing.
Open RVWinWebCamera.pas, set breakpoints on the lines

Code: Select all

      if not FilterGraph.Play then
(there are 3 lines like this).
Does FilterGraph.Play return True?
