logitech orbit with 1.24.2?

[mjskier]

I'm having some issues getting this thing to work on an OpenSuse 11.3 laptop (kernel 2.6.34-12) , ZoneMinder 1.24.2 although I think I'm pretty close. The camera works with vnc, or livcview

zmu only works with the -V1 option (which is kind of odd because from what I was reading around this camera only works with v4l2) Not sure what this is about.

sudo zmu -d /dev/video1 -q -v -V 1

I can set a monitor with it, and the source shows /dev/video1 (0) in orange, so as far as ZM is concerned it knows about the camera and has some level of communication with it.

In the source popup for the monitor, I set
Device Path: /dev/video1
Capture Method: Video for linux version 1
Device channel: 0
Device format: PAL
Capture Palette: YUV422P
Width and Height: 960x720

The monitor window doesn't show anything, and my log keep showing me this message:

If I change the capture method to v4l version 2, I get this in the log:

I'm not sure where to go from there. I've tried to run zmc from the command line, but it does nothing (no error message, no nothing) no matter what argument I try to give it.

Thanks for any suggestion.

Here's something odd: The result of v4l-info shows that this is really a v4l2 device. There isn't much available with v4l version 1.
I'm starting to wonder if somehow I compiled ZoneMinder wrong since I get that signal 6 when trying to set the interface to version 2...

The call that was crashing zmc when using v4l2 was this in zm_local_camera.cpp:385

if ( vidioctl( vid_fd, VIDIOC_S_FMT, &v4l2_data.fmt ) < 0 )
Fatal( "Failed to set video format: %s", strerror(errno) );

I changed the Fatal to a Warning and now I can use v4l2.
I now get messages like the following in my log:

zmc_dvideo1[8195]: INF [Monitor-6: 9000 - Capturing at 14.93 fps]
zmc_dvideo1[8195]: INF [Monitor-6: 10000 - Capturing at 15.15 fps]
...

But still no image...

[mjskier]

I looked at the source for the page that displays the image and it shows
var streamSrc = "http://192.168.1.108/cgi-bin/nph-zms?mode=jpeg&monitor=6&scale=100&maxfps=5&buffer=1000
It should be cgi-bin/zm/nph-zms
I used --with-cgidir=/srv/www/cgi-bin/zm and that shows in zm.conf and where things got installed. So I'm not sure why the zm part disappeared...
If I point my browser to the fixed location I get an image. (iIt is garbled but that's the next step)

[mjskier]

Well that last one is easy to fix: From the zm main web page there is an Options link that lets you specify all kind of stuff. Under the Paths tab there is a PATH_ZMS options which control the path to the zms streaming server.
I'm surprised that's not taken care of with the configure script, but there might ba a valid reason for that?

Also under the Config tab there is a STRICT_VIDEO_CONFIG. From the description, disabling that would make video config errors non-fatal (my issue 2 posts up)

I guess I should read the manual sometimes...
