a week with zm need usb webcam help

[mickey]

Hi
I running a zm 1.25 installation on ubuntu server 11.10.
All went well in the installation process and also I attached 2 IP cameras (FOSCAM) and I can view them in monitor mode.
I want to add a usb webcam and even after a large search I cant really know how to.(I understand that I can use a streamer but I want to try to connect it localy.)
I did zmu -d /dev/video0 -q -v and get this :

I use 2 usb HD auto focus webcams with ZM 1.25 as well as 5 ip cameras. I use mjpg-streamer to connect to the USB cameras and connect ZM as if it is a remote IP camera. This works reasonably well but USB runs out of bandwidth very easily. Look through the ZM Wiki and faq.

This may not be the "right" way but it is the only way I have gotten a local usb webcam to work reliably. High frame rates will saturate usb the symptom is "not enough room on device" errors. Lower frame rate and/or lower pixel size will fix this. Also I use ubuntu so I had to setup udev rules so the 2 usb cameras do not swap with each other when I reboot.

You just need to experiment with source and palette. Try PAL B/YUYV. I'm gonna bet that YUYV does it, not sure about PAL B.

I just got my setup with 2 USB webcams working fine, there is no mjpg_streamer for x64 and I don't feel like learning how to compile from source today. Oddly, with the second camera (A Logitech 9000) it wasn't showing up until I changed the resolution low, and restarted. I assumed bandwidth issues. Then I changed high, and it quit. Then I stopped and restarted ZM again with the higher settings, and it works fine.

You shouldn't have bandwidth problems with a single cam though.
