Ubuntu 16.04 LTS (64 bit) Dell Latitude E5500 Webcam: Creative Notebook Pro (listed as tested and ok for Linux) Cheese 3.18.1
I installed the webcam and fired up Cheese with 640 x 480 and video was fine until I chose to try "photo" with the Kung Fu effect. At that point the screen went black and I got the message "There was an error playing video from the webcam". It could have been in photo or video mode when I selected the effect. I have tried unplugging the webcam, restarting Cheese and even re-booting but all I get is 0.5 of a second of video then the same black screen with the same message. The booth screen is stuck on "photo". I have also tried uninstalling and re-installing Cheese; no change.
I have uninstalled Cheese and installed GTK UVC Video Viewer which displays a video window entitled guvcview. But the main title bar for GTK has no menu and nor has the video window. So I have a functioning webcam and video window but I can't do anything with it, such as record pics or video i.e. there are no File, Edit, Settings e.t.c. options that one would expect in a menu. My question is this: How can I get Cheese or GTK UVC to function properly?
