However, the program is not very rugged in its error handling – because I don't know what I should look for. Below, I first describe the scenario and then ask some questions. Scenario. My program runs on a Fedora system. My version of GStreamer is approximately 2 years old – I can't remember the version number but it is 1.x. I want to be able to take photos of the highest resolution (number of pixels) that the system can support. When I launch camerabin it automatically launches a window for a viewfinder. I do not need the Viewfinder – although it does give the comfort of knowing that the camera is connected. By default, this window is the same size as the capture size – and therefore occupies most of the screen and hides my program's User Interface. (There is an option to specify a size for the Viewfinder window, but unless it exactly matches the capture size, the pipeline will not launch.) What I do (and what I tell my users to do) is to grab the Viewfinder window by the title bar and drag it nearly off the screen, out of the way. Sometimes however, the user will click on the 'Kiss of Death' button at the top right and close the Viewfinder window – and it would seem that this has a fatal effect on the camerbin pipeline. My program does not notice that camerabin has stopped running. Questions <ol> <li> Is there some message/event/signal that I should be able to monitor for to tell me that the pipeline has been stopped (for whatever reason, but especially because the Viewfinder window has been closed)? </li> <li> Can I launch camerabin without the Viewfinder? </li> <li> Is there a way that I can programmatically bring my User Interface to the front or send the Viewfinder window to the back after I have started the camerbin pipeline? </li> <li> Is there a way that I can programmatically control the position of the Viewfinder window before/after I launch camerabin? </li> </ol> An answer to any one of those questions would probably solve my problem.
