[feisty] kopete is very slow when using webcam

Bug Description

Binary package hint: kopete

I'm using feisty and kopete version 3.5.6-0ubuntu5

I have a qc-usb webcam. I've compiled the qc-usb module using module-assistant. the webcam works well.

Kopete gui is veryvery slow when I'm sending my webcam. The cpu usage applet reports ~35%.
The bug stops whenever I close the webcam sending. The bug is not present in other apps (gnome-terminal, firefox)

I want to confirm this bug for kopete 0.12.4, KDE 3.5.6, edgy. The webcam works ok with other programs. In addition to the problems described above I have a video lag up to several minutes. I'm quite sure that this bug did not appear in the kopete version before. Maybe it is associated with the framerate improvement that was introduced in the recent version.

video lag confirmed (30 minutes in my case!)

I confirm the same problem according to Jonas's message. The problem didn't exist before I did update KDE and kopete.

I can confirm the lagging video in Kopete 0.12.7 in Gutsy, with a cam that works just fine w other apps (only not amsn).

Another confirm from me. Gutsy and Kopete 0.12.7 on both (!) sides. GUI slows down a little bit and video is delayed for about 3-5 minutes. I am using a uvc-camera supported by the uvc-driver and v4l2. Other side is using a gspca-cam. Considering the wide variety of camera drivers I do not think it is compatability issue.

Tested again, with my system upgraded to Hardy (kopete version does not change but driver got an update) and Microsoft Messenger (or whatever the name is, at least the original MSN software vom Microsoft) on the other side. Other side had no webcam, though. There were no lags reported, but my gui was still slow. We just had a 10 minutes test. Therefore I cannot say, if the absence of a delay was pure luck or not.

Hi everyone,
I experience the same lag problem, up to 20 min with kopete. Quality is also downgraded a lot. Videoconferencing with Skype doesn't work better, even with the new 2.0.68 version, same downgraded quality and the system can't handle video and sound at the same time. (sound lag as well).

I use a Vaio VGN-FZ-160E with a webcam Motion eye built in, supported by v4l2. The fact that I have to use a 64 version of kubuntu may play a role...

Does anyone have a solution for this bug?
