I have tried so many things I have probably messed this up completely. However, kmotion loads but I get motion errors. "Error capturing first image"

Hi Graham

Cheers

Dave

Well as I easy I am pretty rusty lol

OK 10.04 that's good, latest versions of Debian/ Ubuntu have changed some system permissions that block kmotion

Next can you view your webcam through your web browser ? Also does your webcam support mjpeg ?

Cheers

Hi

By, can I view cam through the web browser, I get to the kmotion
interface if thats what you mean? But no picture. I'll have a quick
google for the mjpeg support

[dave selby]

OK what camera are you using IP / USB ?

[dave selby]

Actually just looked at logs, it looks like USB but kmotion reports a corrupted image ... Have you checked your image size ?

[Graham]

Its a usb web cam Logitech 720hd this is the best data I found so far
about the cam and not sure if it does support
mjpeg. ..http://www.logitech.com/en-gb/product/hd-webcam-c270

[Graham]

No I haven't checked the image size, I wouldn't know how to.

from it, send an email to kmotion-support

[dave selby]

Ok going to check something ...

Just thought I'd mention that when I run the little video4linux tool, it
says that /dev/video0 is using the uvcvideo driver. Is that correct or
should it be using video4linux driver?

[dave selby]

OK I think uvcvideo should be OK, did some digging, although this is not your camera its a logitec HD with the same problem

http://www.lavrsen.dk/foswiki/bin/view/Motion/SupportQuestion2011x01x09x193606

IE the logitec camera firmware is injecting some junk into the mjpeg frames and motion is dropping them, you might even get an occasional snapshot but most will be lost. Looks like a patch was submitted to motion so might be worth chatting to those guys.

http://www.lavrsen.dk/foswiki/bin/view/Motion/WebHome

kmotion uses motion for all the "heavy lifting", if it works in motion, it works in kmotion

Also I would try something, in kmotion set the image size from the default to 1280 x 720, by trying to force a lower resolution out of the camera it could well be causing the "junk"

Good luck

Dave

Dave

[Graham]

Thanks Dave I'll have at these links and see how I get on.

[Graham]

And you're right, I do get that occasional snapshot thing

[dave selby]

One other thought, might be able to flash update your camera ... Just another possibility ...

Ok I followed that first link and at the bottom of the page where he
gives the answer in the grey section I have no idea what I am supposed
to do there.

Not sure I know how to do that either

Had a look for any flash updates for your camera, could not find any so that is probably a dead end.

Best bet talk to motion mailing list
