Hi, I've tried the examples in pigment-python (video.py and webcam.py) and both work perfectly. So, there's no problem with pgmimagesink.
Anna, I don't think my problem is related with my V4l2PlayableModel, because in my current code I don't event use it. The pipeline should work without any parameter from the model. I can only conclude that i have to rewrite the player and the player controller from scratch or start with the current video player/playercontroller and remove piece by piece until the pipeline plays ok. It's going to take a little bit more effort in this part, but i'll get there. I hope :) Rui On Wed, Mar 25, 2009 at 3:50 PM, Anna Wojdel <[email protected]> wrote: > Hi, > > I'm not sure if I'm right, but I looked into your code a bit, and I noticed > that your > function set_current_index(self, index) in V4l2PlaylistModel class which > overrides the one > from PlaylistModel sets self.current_track to self[index].
