I am using a windows XP SP2 computer to run Mach3. I installed a zoom cam camera and tried the video window in Mach3, it worked great but then all the lenses fell out (I unscrewed it to focus it and the vibration shook them out).
So I threw that one away and bought a driverless USB web cam , I tested it using the XP camera viewer and it works fine, but when I try to use the Mach3 viewer I get 'VideoOCX (video) Driver can't be connected', if I ok that message then select the camera, and try to start streaming I get 'VideoOCX (video) Decompresser not supported (try 24bit color depth video format)'.
Any ideas what is wrong or should I just get another web cam with drivers?

Can you get drives for it??? there is not much that I can do to fix that one ;(
-
Nick,
Did you fix your problem?
I know someone with the same issue.
I was wondering if you fixed it. The camera he is using works in windows but not in mach3.
There is no driver for his camera. just an ebay plug and play(sorry plug and pray).

No, I did not find a solution to the problem, so I just bought another camera with software, that did the trick.

Yes - this is exactley the problem I am having. These USB cameras do not come with drivers, they use drivers already installed in Windows. I had a similar problem with on board drivers taking over sound cards on my computer organ system as well.
Does anybody have a driver which we can install, to override the on board driver. This generally cures the problem ???
-
I am the person Rodney highlighted as also having the problem (thanks for posting mate).
Yes it seems that XP takes control of the video stream/control and mach3 then cannot use it - even though I can get the webcam working with other applications. Maybe other webcams with drivers allow for better control of this.
Hopefully someone has a solution for this one. The only alternative is to use another video app (with crosshairs) and then switch back to Mach3 (not ideal, but will get the job done.
Cheers, Jason

Jim, I'll try to find the driver I use this evening and post it up. Not sure it will help you, but we'll see.

Brett - Thanks for that - it is worth a try. I cannot see why the driver in Windows will not work, although, knowing Bill Gates, he would want a percentage of the lathes.

Hi Guys,
Well I think I found the problem. The guys I know that are having the problem all have USB 1.0 ports.
All tho these cameras will work under scanner and camera wizard, they will not work in Mach3 without a USB 2.0 port.
It must need the higher speed for the transfer.
I have tested this on 3 machines with USB 2.0 and it works perfectly, but on my USB 1.0 port laptop I get that error.
I'm waiting on a USB card for the laptop to fully confirm this but it does look like the answer.
Please reply if it does fix your problem.

Hi Again,
Just after I wrote the postI plugged the camera into my home pc and it picked it up ok but said it can perform faster if plugged into a USB 2.0 port.
Stupid window set it as a USB 1.0. I took the opportunity to check it in Mach 3. And guess what that same error.
I plugged it into the port next to it and It came up normally and worked perfectly.
So I through it back into the other port and it work fine.
It’s defiantly a USB1.0 port issue
Grab a USB 2.0 port and test it out.
Also some of these cameras don't like long cables. You need a sheilded and labeled USB 2.0 cable.
A powered Hub helps here too.
Cheers

Rodney - your reasoning seems very logical - both my computers have USB1.
I have ordered a PCMCIA to USD2.0 card for the laptop (my lathe computer). The chap says it will come tommorrow. I will report on it
-
Guys,
Rodney is right. I installed a USB2 PCI card today and everything is now fine. :-)
thanks heaps
-
I must be the odd one out. The PCMCIA to USB2.0 card came and was installed on the laptop. I plugged the camera in, but got nothing, just a black screen on "My Computer" Funnily enough I plugged it in the old USB 1 port(s) and got a picture on "My Computer".
Mach3, however, still failed on USB1 port, and now fails on the USB2 port (which is not suprising).
I found an upgrade on Microsoft for the PCMCIA card to USB, but that failed as well, saying that it could not find some information it needed.
I will keep trying when I get some more time.

Jim, you using service pack 1 or higher in XP? Dont think USB2 worked without the service packs (or updates) I may have the update on a CD here I could email it to you if you dont already have it or service pack installed.

Hood - I would appreciate that - jimpinder@tiscali.co.uk.
I will check for service pack 1 - I thought it was installed - I am sure SP2 is in, but I will check it all again.
Jim

Jim if you have SP1 or SP2 then the update wont help, let me know and if you dont have them I can mail it (if I find it)

Sorry for post on old topic, but need help with video ocx i don't know what is best software to that work fine with that? Thanks!
-
Not really sure what you are asking regarding software. You dont need any software, all you need is a camera plugged in but the camera will have to work with Mach, if it doesnt then maybe try Klaus's video plugin.
