The kernel gives pipmak priorities 15 or 16. It seems that pipmak has
priority 15 while high framerate. But this value does not immediately
switch after changing the framerate. It takes some seconds!

I changed the nice value of pipmak. The nice value affects the priority.
I set the nice value to -8 which caused the kernel to give pipmak a
priority of about 7. This was the "best" priority of all running
applications! So, this framerate problem does not have to do with
application priorities given by the kernel.
