Hi, 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 not start. For illusrate my problem I use the example from pygst tutorial ( simple webcam acquisition and display) : http://pygstdocs.berlios.de/pygst-tutorial/webcam-viewer.html 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.
