Comment 16 for bug 224559

In Ubuntu 9.04 (at least), under System -> Preferences -> Multimedia Systems Selector, under the Video tab, then under Default Input, one can perform certain selections for the Default Input. Here the default in my case is v4l2src from video4linux2, but i can imagine that one can write one's own filter or just modify the v4l2src to rotate the image.

Now, how do I tell applications to use this anyway? I tried setting test input there, but Skype and Cheese never bothered using that - they still connected to the camera.

Is there any merit in trying to do something here? Any further hints or ideas?
