If you're trying to capture 640x480 raw frames to your disk there's a good chance you're overrunning your IO subsystem. Usually I have to compress the data a bit before I try to write it to disk to get the full stream. If you were in windowsland I'd suggest Huff_YUV, but you're going to have to go for Motion JPEG at a high quality setting or something. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
