Hi,
i'm gonna use motion for streaming webcam images with a very large view
angle, so what I get has a big fisheye effect. Is there any chance to do
some preprocessing for the taken images to correct those things?

Might it be be better to do post processing rather than pre. Then you
you would not be wasting processor time adusting images that were just
chucked away as there was no motion.

Well, the result will be directly streamed to a web based application so
there is not really a chance to do post processing.

Do you mean it is streamed even when there is no motion? If so then
there is likely no difference between processing on the way into
motion or on the way out. Either way it is not really a motion
question I don't think. You have a stream coming in, either from a
camera or out of motion, and you want to process it to remove the
distortion. You can either do that by processing the stream out of the
camera and feeding it to motion, or on the way out of motion before
you send it to the web server.
