Picture corruption, 'setup_mode on', 2 Logitech QuickCams

Question

I'm not sure if this is a bug or not, so I thought I'd make it a support question initially.

I have 4 cameras running, 2 of which are Logitech, Inc. QuickCam Easy/Cool (ID 046d:080f), lsusb reports v4l2, /var/log/messages reports gspca.

When running current Debian based distributions (and CentOS 5.5) the images on these cameras are corrupted - as though for a split second cutting and pasting a jagged chunk of text from one part of the picture to another part. This happens randomely.

However recent RPM based distributions I found didn't have this problem. The cameras worked without a hitch.

It was experimenting with Fedora 14 that I noticed that changing to 'setup_mode on' reproduced the corruption of the images on the Debian dists (and CentOS 5.5), and setting it back off fixed it.

Now the motion config files that I used on Debian dists were the same ones on the RPM dists (I.e., with setup_mode set off), so I still don't know why Debian dists should have this problem and RPM not. If I am over Debian way again in the future I will investigate.

At least though now there is a small amount of light on this bug - it had me completely flummoxed.

Paste in your error messages, config settings, terminal window output etc in this text field.

I can confirm this problem - I have 2 microsoft HD-3000 live cams 045E:0779 on different usb 2.0 controller cards

I am running trunkREV359 on ubuntu 11.10 with setup_mode off

The problem is visible when streaming or when recorded - I can provide an avi with the problem showing.

Environment

Motion version:	3.2.12
ffmpeg version:	0.6.1
Libraries:	ffmpeg, mysql, postgresql
Server OS:	Fedora 14, kernel 2.6.35.6

Follow up

Can you reproduce the problem with only 1 camera ?

I tried to reproduce with 1 camera and it worked good.

I get this problem as well on a Ubuntu v10.10. This bug has been reported in the bug section.

I only get this corrupted image with two cameras (Logitech C500), not one.

The corruption occurs on both snapshots and motion images. It occurs in setup mode and "normal" mode.
