can you please provide some more information? with such an incomplete bug 
report its really hard to try to fix anything,

Which datasoul version are you using? Which architecture, java version, desktop 
environment?

I use it here in ubuntu 12.04 with normal cpu usage,..

BTW, it would be helpful to have also:

1. Output of 'top' showing which other processes are also using the cpu. 

2.  Output of a SIGQUIT (in a terminal, find datasoul's PID using 'ps ax' then 
use 'kill -QUIT  <datasoul_pid>). It should give us the stack trace for all 
java threads.

3. Attach VisualVM [1] to datasoul, monitore the threads for a while and report 
which thread is currently using the cpu.

Thanks

Hi,

Thank you very much.

Sorry, I forgot something about the kill -QUIT thing. Please start datasoul 
from the terminal. When you send the QUIT signal the output will appear in the 
terminal where you started datasoul.

I created a screenshot about the VisualVM:
https://docs.google.com/file/d/0B1Uhswwg9w15UVhUeW0tRFU0M1U/edit

First select datasoul's process in the tree in the right, then select the 
'Threads' tab, wait until it fills the screen, take a screenshot and send here.

It would be good if you use the same datasoul session for both, so we can 
correlate the kill -QUIT and the VisualVM outputs.

Do you do anything special or it just starts using cpu after start?

Thanks

Ah, if you could, please send also the output of VisualVM in Profiler tab, then 
click on CPU icon.

I'm trying to reproduce the problem here without success, yet.

Are you using Live or Video as background? 

In VisualVM, if you wait some time do you get other entries beside LivePanel 
and TimerManager?

Hum... this give us a good hint. 

If you disable it (use static background) the cpu usage goes to normal levels?

When you enable the output, does the video run smoothly? How are the cpu usage 
then?

Can you provide us some information about the video (codec, resolution, size, 
etc)?

But if I remove video it has the same effect

So it because of the video !!!

Original comment by YihShan....@gmail.com on 22 Oct 2012 at 9:35

GoogleCodeExporter commented 9 years ago 
That's right, it seems datasoul is playing the video even while output is not 
visible.

I got ~50% cpu usage with the ubuntu example video (How Fast.ogg) as 
background. Your Full HD video should require a bit more cpu usage.

Configuring background to static makes it drop to about ~1% after a while.

I think we can patch it to play the background video only when output is 
visible. I'm going to give this a try when I get some more time.
