Logitech Webcam C300
Logitech Webcam C300
I have installed Zoneminder 1.24.1 on Ubuntu 9.10. I can't get Logitech Webcam C300 (it is UVC-camera) to work with it. Has anybody else gotten this camera to work?
The camera works fine with xawtv. It also works with ffmpeg when launched from CLI, but source in ZM-console keeps showing red.
In /etc/sysctl.conf I have set kernel.shmmax=1073741824.

$ sudo zmu -d /dev/video0 -q -v gives:
Error, failed to get channel 0 attributes: Invalid argument
I don't know what happened, but when I tried every option from "Source" -> "Colour Palette" and when it was set to YUYV - camera now works.
Odd thing is, that it was previously already set to YUYV, but it didn't work then... but after I changed it MANY times back and forth.
And still "sudo zmu -d /dev/video0 -q -v" gives me: "Error, failed to get channel 0 attributes: Invalid argument"
???
But somehow it now works...

The camera works now with 640x480 resolution, but I can't get it work any higher levels.
Have I calculated following right?
Total physical memory = 3GB
3000 x 1024 x 1024 / 4096 = 768000
-----------------------------------
kernel.shmall = 768000
1 x 800x600 resolution camera, 40 frames buffer, YUYV palette (YUYV = YUY2, 16 bit?)
800 x 600 x 16 x 40 = 307200000 + 10% = 337920000
337920000 / 8 = 42240000
------------------------
kernel.shmmax = 42240000
Is this "kernel.shmall < kernel.shmmax" correct?
So - I have bigger kernel.shmmax value than 42240000, but camera won't work with anything higher than 640x480.
