I use a Logitech C920 webcam on Fedora 20. It works, but the resolution seems to max out at 640x480 in most webcam-using applications. In Google Hangouts things look particularly horrible.

I can easily get high-quality video off this camera via gstreamer, using e.g.

gst-launch-1.0 -v -e v4l2src device=/dev/video0 ! queue ! video/x-h264,width=800,height=448,framerate=30/1 ! h264parse ! avdec_h264 ! xvimagesink sync=false

What do I need to do in order to enable other applications to see these resolutions by default? I particularly care about improving things in Google Hangouts.

The camera support on Fedora and Google Hangouts are two separate issues: please contact the relevant forums http://www.forums.fedoraforum.org/forumdisplay.php?f=8 and https://productforums.google.com/forum/#!forum/hangouts

Let me follow up here to answer my own question. First, I did ask on the Google Hangouts forum and got no responses — rather disappointing. Second, I eventually figured out the problem: I had the camera plugged into a crappy USB hub. Once I attached the camera directly to the computer, the quality went all the way up to 1080p in all applications.

To conclude: the C920 works perfectly on recent Fedoras — just make sure to give it at keast USB 2 sockets. Yay.
