Perhaps there is a third option:
- instanciate a PVideoOutputDevice_GDK from inside PVideoOutputDevice_XV,
convert the frame on
receipt from YUV420P to RGB in PVideoOutputDevice_XV and send them to the
PVideoOutputDevice_GDK
instance? Is that possible? I would like to keep the XV and GDK output code
separated... Perhaps
it also makes sense to move some of the outut code in main.cpp to
videooutput_gdk.cpp?
