This message means that your table needs repair, however, the option for repair through the phpmyadmin interface is not available.
Therefore, you need to open a terminal or ssh and run the following commands:
1) cd /var/lib/mysql/DATABASE (where DATABASE is the one containing the table that needs repair)
2) myisamchk –safe-recover TABLE (where TABLE is the table you are trying to repair)
Your table will be fixed in a few minutes!
There are several reasons this problem could be caused. In my case, running Yosemite 10.10, Photo Booth had a black screen and the menu was saying “no camera connected” although FaceTime worked fine.
The common sudo killall VDCAssistant solution didn’t work at all, as well as, reseting my NVRAM.
After a lot of debugging and trial and error, I found out that the problem originated from the fact that I used Dropbox and had created a symbolic link in the place of the ~/Pictures folder.
The solution is to open ~/Library/Preferences/com.apple.PhotoBooth.plist with Xcode and change the link of ~/Pictures/Photo Booth Library to the absolute path of your new pictures folder.
