webcam freezes after 10-30 seconds

[Sezer Yalcin]

This is probably a kernel module or low level library problem (gsteamer?) Same issue happens with other webcam applications including:
Skype (4.1.20)
Google Gtalk browser plugin.

I would be happy to point this to right direction.

Looks like I missed last steps in backtrace generation. I will redo and upload new file.
What I see now webcam showed up at /dev/video1 after failure then back to /dev/video0.
Now I can't reproduce and it is working fine.
This happens on skype as well. I disconnect calls when webcam cause problems. After a few tries, it is working fine.

Status changed to 'Confirmed' because the bug affects multiple users.

[Luigi R. (xluigi84)]

I have the same problem. I have noticed it using Skype 4.3.0.37 on Ubuntu 14.04 using the official kernel 3.13.0-37-generic. If I do not activate my cam everything is working fine but as soon as I switch on my cam the audio start to be unstable and the video freeze.

In my case it does not affect cheese.
