I use gstreamer and pygtk for webcam acquisition. Since I upgraded to
ubuntu karmic 9.10, I was facing some application freeze/crash.
Most of the time the application freeze and webcam application does
For illusrate my problem I use the example from pygst tutorial ( simple
webcam acquisition and display) :
This program operates normaly on ubuntu dapper drake and ubuntu jaunty
jackalope. I execute the program at least 5 times and webcam
acquisition, is always OK.
If I execute the same script on ubuntu karmic, sometimes its ok and
sometimes not. Most of the the time the webcam acquisition fails.
What I noticed under karmic :
If I use videotestsrc instead of v4l2src, I still having the problem
--> so its seems not due to webcam acquisition.
When display is not 'forced' to a Drawing area, i.e. the
acquisition starts in another window in place of application window, the
script never crash and webcam acquisition is good. For doin that doin I
don't connect the signal 'sync-message::element'
Do anyone has facing this problem or have an idea for how to
understand/debug this problem.
I post this message on gstreamer and pygtk, because I do not know where
the problem or bad usage come from ?
Thanks in advance for help.
