Facetime Camera issue - No Video
I am using Mac book pro with MacOS High Sierra 10.13.3. Recently I have been having issues with FaceTime. Whenever I start my FaceTime, I get the following message
No Video
FaceTime has not received any video from the connected camera. Restarting your computer may fix this issue.
However, restarting the computer does not fix the issue.
Apps like Photo Booth, skype which uses camera also is not working.
Please help resolve this.
