Description Guillaume Duveau 2008-11-17 18:36:32 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.

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 ?
Comment 4 Stefan Sauer (gstreamer, gtkdoc dev) 2008-11-19 20:21:38 UTC
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.

Comment 6 Guillaume Duveau 2009-01-05 09:20:25 UTC
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

I suspect a driver issue:

now that we use libv4l inbetween that fixes some of the colorpsace issue of camera, it should work better.

Guillaume, are you still facing the problem?
