greetings

Some more info.  I've paused the detection on one of the cameras, (the pro 3000) and the orbit caputed some motion, it was only 3 frames total. 
    frame 1 09:32:35-01
    frame 2 09:39:52-00
    frame 3 09:39:52-01

frame 1 had the outline box around the pixels, then it jumped ahead 7 minutes and only captured 2 more frames.  (the post capture is set to 10...)  the snapshot jpeg is timestamped the same as frame 1 in the avi.

This machine is not really doing much else, its just sitting in the livingroom.  its running httpd2 to serve the output directory, and the cambozola applet. (no one's connected though, at least I think..)  I have the web interface at an obscure port. I'll have to check the logs at home to see if anyone's hitting it, but I'm pretty sure I'm the only one.

I'm using ffmpeg with the msmpeg4 encoder.

Thanks and kind regards,

Subject: multiple cameras detecing motion video skips 4-5 minutes

Greetings,

I'm running the latest release of motion, on Mandriva Spring 2007.1.  

I have 2 logitec cams, one orbit (the old kind that works with pwc), one webcam quickcam pro 3000.  and no cable extenders.  just what came stock with the cameras.

I can control the orbit as expected from a web page, everything is working like I expect. (props to the authors) but I think I may have an issue, and I"m not sure where to start. to fix it.  I've got the resolution for both cams set to 320x240, max framerate set to 2. most of the other setting set to default in the configs.  I think I've throttled back everything that I can to conserve resources,  (no precapture, reasonable framerate, I'm not using the deprecated low-cpu setting.)

I'm running it offa laptop that's a compaq n620c (1.4 Ghz with 1G ram plenty hd space) with usb 2.0.  I think there's only one usb controller chipset though.  

Here's the crux of the issue,  When both cams detect motion it will capture a couple of frames, the skip between 3-6 minutes of frames and then capture another couple of frames..  and miss the majority of the motion..  its strange.

I'm not sure where the bottle neck is.  I have a couple ideas, but I wanted to see if the list could point me in the right direction and save me some time.

the laptop has usb 2.0, and this smacks of not enough usb bandwidth.   any ideas??

Thanks and Kindest regards,

Fred
