guvcview not working with logitech c270 webcam
I recently purchased a logitech webcam c270 and it works with cheese; however, it doesn't work with guvcview. I completely purged cheese from computer. Then I removed and reinstalled guvcview, but still not working. I've even tried to start from command line. but no luck. Any help appreciated. Thanks anyway here are the logs. for anyone brave enough... I think I might be missing right driver and/or codecs (video)

Your system? With 16.04 I can make it works. Try low value for exposition, like:
I got tons of errors too.
