Post subject:  CamUniversal, DirectShow FilterGraph, Windows 8.1

Hi,

I have been running CamUniversal successfully on Windows 8 for some time. Foolishly I decided to upgrade to Windows 8.1 and now I get the following error dialog at startup:
Video Device: Logitect HD Webcam C615
......
Could not create DirectShow Filtergraph!
....

The dialog indicates that install-filter.bat should be run to reinstall the filters. This runs successfully but does not change the recurrence of the error at startup.

Is this a Windows 8.1. specific issue for CamUniversal?
If so, will you be testing/compiling for Windows 8.1 in the near future?

Hi,

I haven't tested with Windows 8.1 yet. But I don't see a reason why it shouldn't work.

Please run the install_filter.bat as administrator.

Did you add the camera new from scratch to CamUniversal?
Please try this. Perhaps the camera source filter or an interim filter has renamed.

Please, try first always without video/audio codecs.

Thanks for the suggestions. Its up and running again.
FYI: Removing and adding the cameras back got one working with the second having a black screen with a rectangle of green fuzzy pixels on the bottom.
After I stopped and restarted camera preview both it all came good and was operating the same after reboot tests.
