Hi,
I have a Logitech QuickCam 9000 which works really nice during daylight with
Skype 2.0 Beta.
Skype starts the Video-Calls with 15fps settings (dwFrameInterval: 666666)
wich works nicely. After some time, it changes the fps to 30fps
(dwFrameInterval: 333333) and the cam locks up.
The only possibility to solve this issue is to unplug the cam completely from
the computer.
I have added a few lines of debug code to the uvc module I will attach to this
report. Additional I have attached the output of these debug lines to syslog.
Maybe you have an idea, what's going wrong here. Skype told me to get in
touch with you, since it works during daylight but not with bad light during
the night.
If you would have any patches to test, I am more then willing to test them.
I hope you can help me with this issue,
thanks a lot
Philipp
