What is the problem?
Cam is not working after Update from 1.8.7 to 1.9.1 the Field for the Cam is black. /webcam/?action=stream shows me the working cam-image in a new TAB.
I´m using "Consolidate Temp Control" and it is the second time that the camera field is black after an update from Octopi.
To solve this, I first have to uninstall "Consolidate Temp Control" over the Pluginmanager, restart and then reinstall it and restart again.
After that, the cam-image works again in the Command&Control tab. I wanted to share for others who have the same problem if using "Consolidate Temp Control"
