Ubuntu – Is Logitech HD Webcam C615 supported

This comment on the forums confirms that the camera works when you're plug it in. The older C500 shows up as supported in Linux on the Logitech page, but unfortunately that page hasn't been updated for the C510.

However mrubli from Logitech posts on their forum:

All these cameras are UVC compliant and work well on Linux.

So you should be good to go with support; as far as being able to encode with the GPU and all that you might want to split those off into seperate questions so we can get down to specifics.

I personally have had great success with Logitech webcams in Linux and I can do Cheese, Skype, and Google Talk, etc with an older Quickcam STX, if you end up with this webcam please leave a comment on how well it works!

I experienced the same issue, although I was able to resolve it with Guvcview. As I understand, the problem is that the software re-encodes the already h264-coded video stream from the camera.

When I set the codec to "raw video codec", I got crystal clear picture without the hesitating artefact. So: Video menu > Video codec > Raw camera input
