Just a thought: If you script actually reads like this (serial 
execution) it's dumping the entire stream.yuv into the fifo before 
encoder_example gets run to drain it. So it may start blocking if
the fifo hits some limit. Try changing the semicolon (;) at the end
of the mplayer invocation to an ampersand (&). Or if you're invoking
all this from the command line, insert the & before the ;. That will 
make the two run at the same time.
