Title:
Black video from webcam in Cheese and Skype
Status in cheese package in Ubuntu:
Incomplete
Bug description:
The following bug affects both Cheese and Skype, but not guvcview.
I had an intermittent problem of the video feed from the webcam
failing, apparently after waking from sleep. When I opened Cheese or
the video in Skype I would see just black. When this happened the
light on the camera would not come on. However the video feed to
guvcview continued to work fine and the light would come on in that
case. I noticed that this problem became a lot less frequent when I
switched from Unity to XFCE, as did another problem of networking
failing on waking from sleep, so I suspect there may be a connection
between these two problems.
What used to happen was that I would either reboot or simply log out
and log back into my gui session and the video from the camera would
be restored. However when the problem reoccurred yesterday nothing I
did would bring the video back to Cheese and Skype, not even
rebooting, running Cheese as root or starting a gui session as a
different user. This means that video to Cheese and, much more
importantly, to Skype is now permanently disabled. The one thing I
noticed as being odd which might possibly have contributed to this
situation is that when I logged out of my gui session and tried to log
back in again, the gui failed to launch and I ended up having to
reboot.
To summarise:
- Webcam video to certain applications, including Cheese and Skype, sometimes
fails.
- At least one application, namely guvcview, is not affected.
- The failure is sometimes capable of persisting through several boot cycles.
Needless to say, not being able to do video chat is a very serious bug
and a very good reason for a user to look for another operating
system.
