commit 72517f6267fd63539a85b436509c7e250d48897b
Author: Filippo Argiolas <filippo argiolas gmail com>
Date: Sat Dec 12 21:12:53 2009 +0100
First pass at some reorganization of caps handling
Gobjectify CheeseDevice.
Move video format stuff into CheeseDevice, trying to use gstreamer functions
whenever possibile (i.e. caps manipulating stuff).
Remove framerate code. We just use the maximum framerate since some time now
and gstreamer is quite good at picking the best rate, no need to do that here.
