Testing USB webcam with mplayer
I've noticed a mplayer's issue on OpenBSD. With different desktop machines and usb webcams I've successfully tested the webcam with the command: $ mplayer tv:// But in all cases, when you press 'q' mplayer hangs for some seconds before quitting. Any idea of why this happens?

USB Webcam
I would like to get a USB webcam working on my PowerPC OpenBSD 4.9 install. I'm an OpenBSD newbie. When I plug it in, the kernel registers the USB device, but doesn't go any further to recognise it as a video device. The last line of dmesg is: ugen1 at uhub1 port 1 Vimicro Corp.
