I had the following error with cheese: 
"libv4l2: error got 4 consecutive frame decode errors, last error: v4l-convert: libjpeg error: End Of Image"

sap@warzycha ~ $ lsb_release -a
Distributor ID:	LinuxMint

 1 [C170           ]: USB-Audio - Webcam C170
                      Webcam C170 at usb-0000:00:1a.0-2, full speed

This did the trick for me was:
1. (install guvcview using "sudo apt-get install guvcview" and) open guvcview
2. close guvcview
3. then open cheese and the webcam works!
