Hi all,

I've been trying to shave off precious cycles off the FW camera input capture. The problem is that vanilla capture of a FW camera feed (NTSC) already introduces 50+% of CPU overhead on an AMD64 3000+. I have experimented with lowered gem frame value, but anything below 20 seems to jagged.

So, here are the questions:

What is the cause of such a high capture overhead?

Is there a way to minimize such overhead beyond just optimizing code for sse and other similar methods, plus the aforesaid frame option for the gem object?

Many thanks!

Best wishes,

Ico
