[Bug 332381] Re: cheese records at a painfully slow fps

[tidris]

I have a similar problem but on much faster hardware, a 2.4GHz Intel
dual core2 laptop with a 1.3MP built-in camera. I run ubuntu 8.10 with
all the latest updates. Many seconds by between video frames.

Today I discovered a way to work around this problem. What I do is run
this script on a terminal window.

 while true; do echo > /dev/null;  done

That script keeps the CPU busy. When that script is running cheese
displays video at a reasonable frame rate. Stop the script and frame
rates goes back to super slow.

I think this is related to the automatic CPU frequency adjustment in the
laptop. When the script above is running the CPU applet shows the CPU
frequency as 2.4GHz. When the script is stopped the CPU frequency stays
at 800MHz even if cheese is running and trying to capture video.

So maybe this isn't really a cheese bug, but perhaps cheese should try
to force the CPU to run at maximum frequency when it is trying to
capture video?
