Another tab for WebCam

Hey guys, I know this gets old but
I followed psha.org.ru/b/camview-emc.html and I only see a black screen
The cam works using guvcview
In camview I add the camera and opengl to the chain
The camera says streaming and opengl says off
I tried the example input and vivi and get the same black screen
I also tried installing libgl1-mesa-swx11 and get the same
Running lucid and linuxcnc2.5

Thanks

I have an issue that the picture flicker badly - but only when embedded.
If you run camview or camview-emc standalone you will see a nice steady picture.

Any ideas to try to trouble shoot?

Hi All,
Just got camview working with LinuxCNC. All okay until I jog the axes then image feed becomes jerky then stops all together. Running 2.5 on a D510 Intel motherboard, Ubuntu 10.
Anyone got any ideas whats going on?
Regards
Andy

following the wiki to a T and logged in as root.

when I type apt-get install camview I get the message couldn't find package camview.

Any help out there?

I am usin Linuxcnc 2.5 and I am able to open the Camera tab but no x,y,z measurements. Help.

Hi all,
I need help to solve an issue. I'm using LINUXCNC 2.5.2, Ubuntu 10.04 and a cheap webcam for my CNC project. The thing I have to do is to extract co-ordinates out of camera (x,y). So I followed this link.

wiki.linuxcnc.org/cgi-bin/wiki.pl?Axis_Embed_Video

I installed the repository and camview-emc. Then I edited the .ini file with in [DISPLAY] section-

EMBED_TAB_NAME = Camera
EMBED_TAB_COMMAND = camview-emc -w {XID}

Till here the camera works superb. But once you start following the steps further camera doesn't work only a tab for Camera tab can be seen. I'm attaching a file for the part where camera is working.

Help needed. Thanks in advance..

What steps are you following?

Have you installed camunits-plugins-emc?
(this is what contains the code for the DROs)

Hello,

Thanks for replying. I'm attaching file of steps followed from the link in a pdf file.

I think I'm wrong following them bcoz I'm using Ubuntu10.04 and linuxcnc 2.5.2. Yes I have installed camunits-plugins-emc following the link

psha.org.ru/b/camview-emc.html#fig:camview-emc-axis

One more question I have. I was also trying to test this in my laptop. I could add the repository but when I had to install camview emc it said couldn't find package. So
is it possible to install this on laptop, including the camunits-plugins-emc? I'm attaching a screenshot of it.

The addition to the actual wiki was made 2.5 years ago, it relates to 2.5~pre-release running on 8.04
and what it describes is not necessary to getting a DRO displayed, that is covered in the main wiki.
It is supported only by its author, if you can find Bonny.

If for some reason you cannot get the DRO displayed in the screen, you can always add a pyVCP panel with 3 float number widgets connected
to halui.axis.n.pos-relative, so the readings are visible when the camera is on

I had to install camview emc it said couldn't find package.

The screen shot shows you did a apt-get upgrade for some reason, but not apt-get update which is required to fetch the lists for the repo you added.

psha's server is down, so I can't check if the paths are still correct, but since you presumably downloaded from there on your other computer,
it is something you did differently on the laptop which is the problem

Hello...

Yes. That was done on 8.04 and release 2.5~pre. And still work in that. (isn't broken so I didn't update/change anything)

But I remember that this extension was working on newer release to. It's best to try to contact psha as the actual work is from him.
I tryed to do myself but without succes and psha then help me to got result.

But issue is strange, as we didn't touch DRO tab at all.
Maybe just axis was changed (in that time as I know PyVCP can't be tabed) so code in tabs is changed and probably prevent correct workflow of CAM.

I just wonder why the CAM isn't supported from LinuxCNC itself.

But today is probably easier to make PyVcp tab inside axis and put cam in that pyvcp panel. This should be easyer.
