I've run the live cd 1.20 and all went ok until I added my first monitor. I upgraded to the 1.21.2 RPM and the same happened. So I re-formatted, re-installed and got the same. The 'video' shows up as a 'broken link' in firefox. I don't know how to do screen grabs yet...

[user user]$ sudo -u root zmu -d /dev/video0 -q -v

Dunno if this is relevant from the zm logs:-

I'm running on a Toshiba laptop, the webcam works in Windows, the usb works as the usb mouse works ok and I'm clueless about what to do next

Any help appreciated.

Neil

Hi Neil,
Thank you for providing good info for debugging Other users please note how to ask for assistance

The output from zmu indicates that the driver has loaded and the cam is recognized.

Maximum Width: 400
Maximum Height: 300
Minimum Width: 2
Minimum Height: 2

Try setting the Width and Height in the monitor form to 400 x 300.
Try also both setting the palette to RGB24. (Looks like it may be set at the default grayscale, which may or may not work.)
Im not sure whether the format (0=PAL,1=NTSC etc) makes any difference with a usb cam so try switching if the above does't get you going.

argument]

This is the usual error when the monitor is set to a size that the device doesn't support.

You can also uncheck ZM_STRICT_VIDEO_CONFIG if it's checked. It's in the Config tab of the Options window in ZM

Let us know how it goes.

Best regards,

Ross

I can't take any credit for the logs - I just put in what others had in other posts. Guess I got lucky

http://www.aiyamicro.com/pc-parts-perip ... ebcams.htm

shows that the resolution is 320x240 or thereabouts, so I'll try that tomorrow. (Don't know why it says 400x300 in the config )

Thanks for the swift response!

Neil
