Comment 1 for bug 872053

The Problem is due to transition if gstreamer base to version 0.10.32.

For making snapshot luciole use the 'probe' functionality of gstreamer via add_buffer_probe function.
This function no more works in natty with pygst. Reason : I don't know. This function is not really supported and considered as a hack.

So the way to make image snapshots shall be changed. The 'handoff' signal ( http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-data-spoof.html) is used on the last sink for image save pipe.
The advantage of this method is that Jpeg encoding is no more necessary on all the frames, only the captured one is encoded in Jpeg and stored in hard drive
