Seems that you are talking about video playback only. From my last email, you 
can see that our products needs to play video and run other stuff together. 
Can  you provide more detail about how it works with OpenML. If i want to 
play video and reading messages from server at the same time, how it works 
with OpenML? This can be done by using cairo/glitz. Sorry about my stupid
