Hi Carl,

Thanks for your answer, it looks like you are right about performace,
reducing de frame rate to 5 or even 15 it gets much much better. Source has
a framerate of 30 so it might be too much for my processor.

I'll check right now the head of the git repository and see what happens.
By the way, what -strict and -2 flags means?

Thanks again!!
