Hey, developers: Alfred Van Hoek has released the
VideoOut plug-in for the REALbasic editing environment from
Real Software. It demonstrates how QuickTime Video Output Components can be used to play video out to hardware. A common use would be playing a DV stream (.dv file) out QuickTime’s FireWire Video Output Component and recording it on a DV camera.

The plug-in contains the VideoOutComponent and VideoOut classes. VideoOutComponent uses the component descriptions of the Mac operating system. If a valid component instance is created, you use this class to obtain the default settings from the VideoOutComponent, to present it to the user, and let the user alter the settings. The client is able to design a settings dialog — or even avoid the presentation of such a dialog.
The constructor VideoOut uses one flavor of an instance of the VideoOutComponent. The plug-in protects the client from several hassles you currently only can prevent by changing the code, Hoek said.
To use the plug-in, you must put SoftVOutComponentPPC in the extension folder to run it in Mac OS 9, and SoftVOutCarbonCFM.component in the QuickTime folder when running Mac OS X. These files comes with the plug-in.
