I am pretty sure it is some signed/unsigned problem in interpreting the value.

In the original sources (grabber.h ?) the threshold is fixed at 48, I wanted to experiment a little bit with different ones, because in some situations (e.g. poor lighting, or neon lights) the output of the camera can be very noisy and it pays to raise the threshold. > And someone needs to fix the vic port -- it blows up if the qcam-grabber > is built on my machine.

I am still having the qcam driver compiled in into 2.2.1 and it seems to work. cheers luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
