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

Re: Web Camera not Working
Please do additional testing.
Open RVWinWebCamera.pas, set breakpoints on the lines
(there are 3 lines like this).
Does FilterGraph.Play return True?
Open RVWinWebCamera.pas, set breakpoints on the lines
Code: Select all
if not FilterGraph.Play then
Does FilterGraph.Play return True?
Re: Web Camera not Working
Yes, it does return true in TRVWebCam.PlayVideoStream when I press "Camera On".
Yes, it does return true in TRVWebCam.Set_CamVideoMode when the camera is on and I switch video resolution.
I don't think it is being called in TRVWebCam.Set_VideoResolution.
What is the next step? Thanks!
