Changes

The use of QuickTime was deprecated in version 8.1 of LiveCode with new defaults for dontUseQT and dontUseQTEffects as true on all systems apart from pre OS X 10.8. The Windows build of LiveCode no longer supports any QuickTime features and setting the dontUseQT and dontUseQTEffects will have no effect.

Support for the "Video Grabber" library on Mac OS X ended in LiveCode 9.0.

Description

Use the revVideoGrabDialog command to specify settings for use with the video grabber.

You must use the revInitializeVideoGrabber command to open the video grabber before you can use the revVideoGrabDialog command.

Use the settingsType parameter to specify which dialog box you want to show.

Note: Some video camera drivers don't support some settingsType values.

Important: The revVideoGrabDialog command is part of the Video library. To ensure that the command works in a standalone application, you must include this custom library when you create your standalone. In the Inclusions pane of the Standalone Application Settings window, make sure the "Video Grabber" library checkbox is checked.
