I got iglasses to lock the exposure in 10.6, I built the app as a 32 bit app because they said that it needs to be 32 bit to control the video driver.
Go to your Applications folder in the Finder and open the iGlasses folder.
Right-click (or ctrl-click) on iGlasses Manager and select Show Package Contents.
Drill down to Contents/Resources.
You need to edit the file apps.plist. I use Apples own Property List Editor which comes with the Developer Tools
You need to add a new sibling. If youre using Property List Editor, just click select one of the existing items (under Root IGSupportedApplications) and click the Add New Sibling button. If youre using a text editor, copy and paste one of the existing strings onto a new line and edit it.
The sibling should be called com.yourcompany.openFrameworks (this is the bundle identifier that is packaged in the apps that are built) Its class is String (the same as the others) and its value should be OF (or anything really, this is just the name iGlasses uses).
Save the Plist file (if youre using a text editor, dont forget to convert it back to binary see instructions at link above).
Go back to your Applications/iGlasses folder and double-click on iGlasses Manager to open it.
You should see a new entry in the list for OF, but it will be unchecked. Tick it, then click Apply. Youll have to type in your admin password.
Quit and reopen your app. You should now see the iGlasses Settings item under the File Menu.
Those steps worked for me. You can switch back and forth between the videograbber settings and iglasses it seems, although I need to test this further.
Wish there was a better way to do this.
Anyone else have any luck?
