Unity4.2 Win7 Webcam crash

August 29, 2013 - 9:13pm #1

Vuforia SDK Version: 2.6.7 -

Description with steps to reproduce:

Win  7 Pro deskto with Unity 4.2 and Logitech C615 camera (different camera - same results)

Simple scene with ARCamera Prefab and FrameMarker set to 0.

When play this scene the editor shuts immediately with no error message.  Compiled version does the same. Brings up Unity player config box, but shuts immediately on pl

When I select 'Dont't use for Play Mode" on the Web Cam Behaviour script at least the editor does not crash. If I remove the script, player still crashes.

Running the "framemarkers-2-6-7.unitypackage"  produces the same results.

I have tried disabling Auto Refresh as in a previous post with no effect.

No issues on an iMac OSX or porting from it to iOS or Android. Just this Win7 box which had been fine prior to the Update to 4.2 and VU 2.6.7

Thanks, Peter

Development OS (Mac OS X, Windows, Linux): Win 7 -

Mobile OS and Version: Mobs fine only desktop problem -

Mobile Device Manufacturer and Model name: No issues -

Great to hear that!

Thanks for the update.

Unity4.2 Win7 Webcam crash - no longer

Unity 4.2.2 has fixed the crash on this device. Now running beautifully and stable in the editor.

Woo Whoo

Ok, can you send me a link to some Dropbox via PM ?

What may be interesting is to compare my packaged version that doesn't work to the packaged version that you create on one of your machines that does work?

(AR Camera Prefab only. No other objects in scene).

Regards,

Peter

No need to provide the project, we can recreate it easily;

but I will add a note for our engineering team about the 2 machines that you mention here.

Thanks.

Maybe not.  The packaged version with just a AR Camera prefab and nothing else, won't run on a Win 8 Samsung notebook or Vista notebook.

I could always provide you the project and the compiled test module?

Maybe via dropbox?

Let me know if I can help.

Thanks, Peter

Ok, I have brought this to the attention of our team for investigation,  though this may be a bit difficult to reproduce (as this does not occur for instance on several Win machines we have tested on... so it might be something specific due to the camera driver and/or your machine setup....)

Hi,

No, just a normal PC running Win7.  Tend to do most my development on it (3 monitors attached!) except when I need to do iOS and Android hence the iMac.  Since our Vuforia App is iOS and Android based, I hadn't picked up the issue (only recently upgraded from Unity 4.1 to Unity 4.2) until I moved it back across to the Win7 machine to test out our Supervisor module monitoring the progress of our learners (clients).

I do have to say how impressive Vuforia has become. We are developing a health training based app using specific external hardware that has a moving target. The competency of the learner is measured by the movement of the target. We are able to monitor up to 180 rotations per minute on good devices (ie. iPad or Sony Xperia). Unfortunately the Galaxy et al are not in the same class, but give acceptable results.

I have tried 2 different cameras, and disabling the Web Cam script on the AR Camera prefab at least prevents Unity crashing. Since it happens with the AR Camera prefab only in the scene, that might give a clue to those more knowledgeable than me.

Thanks, Peter

Hi, one question:

can you be more specific about Win Box ?

do you mean that you are running a WinBox installed on your Mac ? or something else?

Greetings,

Yes, happens on Unity 4.1 also.

Happens with the image targets sample.

Happens if only the AR camera prefab is in the scene and nothing else.

Of course happens on the AR app we are actually building, but it runs fine on the Mac OSX, iOS and Android platforms with the same config.

This Win Box is my main developing machine and most things I develop are done on it.

Very strange...

Hi,

have you also tried other samples, such as Image Targets or others ? or is this just happening with Frame Markers ? (would be useful to know);

Does it happen with Vuforia 2.6.7 on Unity 4.1 ? or just on Unity 4.2 ?
