yeah, that is what i basically do. when i do 'cat mypipe' and in another
terminal 'echo foo > pipe', i see 'foo' in the first terminal. so, with
cat and echo piping is working as expexted, but when i do:

mplayer -vo yuv4mpeg:file=mypipe

and in another terminal

theora_encoder_example  mypipe

nothing happens. both commands just wait. can somebody confirm this?
