GUVC
 

When I start a video in guvc in kubuntu 15.10 the video runs for a second and then goes black. I worked well in 15.05 need some help.

More information would be helpful. For example:

How is the video encoded (avi, mkv, etc.)?

Does it work in other media players? Which ones?

Is the video publicly available so that others can test it?

Later:

Another thought came to be during the night. Try starting playback from the command line. Some helpful error messages may be thrown to the terminal.
