GNOME Bugzilla – Bug 561259
Logitech Quickcam Zoom doesn't work
Last modified: 2010-12-01 02:00:16 UTC
Please describe the problem: It works well under camorama, kopete, ekiga, ... so maybe the situation is not so desperate. Steps to reproduce: 1. plug in the webcam 2. launch gstreamer-properties 3. try any of the settings Actual results: The video output is a green square. In the shell I also get these warnings but I think it has nothing to do with the webcam : gstreamer-properties-Message: Skipping unavailable plugin 'artsdsink' gstreamer-properties-Message: Skipping unavailable plugin 'glimagesink' gstreamer-properties-Message: Skipping unavailable plugin 'sdlvideosink' gstreamer-properties-Message: Skipping unavailable plugin 'v4lmjpegsrc' gstreamer-properties-Message: Skipping unavailable plugin 'qcamsrc' gstreamer-properties-Message: Skipping unavailable plugin 'esdmon' Expected results: To see me with the webcam :) Does this happen every time? Yes Other information: I hope this can be fixed, many thanks in advance !
Can you please attach the output of v4l-info. Please also try: GST_DEBUG="*:2,v4l2src:4" GST_DEBUG_NO_COLOR=1 gst-launch 2>debug.log v4l2src ! autovideosink and attach the log.
Created attachment 122942 [details] output of v4l-info Hello ! Please find here the output of v4l-info !
Comment on attachment 122942 [details] output of v4l-info Also, there's no output for the line : GST_DEBUG="*:2,v4l2src:4" GST_DEBUG_NO_COLOR=1 gst-launch 2>debug.log v4l2src ! autovideosink Or should I run v4l-info again ?
The log from v4l-info looks good. What happens if you run GST_DEBUG="*:2,v4l2src:4" GST_DEBUG_NO_COLOR=1 gst-launch 2>debug.log v4l2src ! autovideosink ? Any window opening? Can you please attach the generated debug.log file? Also please tell us which distro and what gstreamer versions.
Created attachment 123231 [details] debug.log Hi, Yes a window opens but it is all green ! Please find attached the debug.log. I have gstreamer 0.10.21 on Ubuntu 8.10. Thanks a lot for following this !
Any progress on this ? By the way I had a similar problem with Kopete, it was the video palette that needed to be corrected, maybe this can help ? http://bugs.kde.org/show_bug.cgi?id=140528
