Hello, I'm trying to play various videos with kaa.popcorn one after each other. I want also to start the next video when the user hits the spacebar. With the mplayer backend it works but the window flickers between videos. I've seen that the same behaviour is present in Freevo2 so I think it's mplayer's fault.
I've tried then with the xine backend but I get the following traceback
randomly. Attached is the program I coded so far.
To run just do
video2.py ~/videos/*.avi
and press spacebar to start watching the next video or get the traceback
