Re: Using QTNewGWorldFromPtr() with SetTrackGWorld()

I'm working on some movie playback...the application wants the actual
decompressed video for each frame (as it blits it to different in game
windows it manages). Playback currently works fine, but I'm hoping to
remove an unnessecary copy. Currently, I'm creating a standard GWorld and
using SetTrackGWorld() to have QT draw into it and notify me that a new
frame is ready. When a new frame is ready, I copy the data from the GWorld
into an internal buffer that the app uses.

I'd like to use QTNewGWorldFromPtr() to create a GWorld that points to this
resident internal buffer. Creating this new GWorld and setting it with
SetTrackGWorld() doesn't return any errors. But no data is actually being
decoded into the new GWorld.

Is it possible to do this? Or are GWorlds created with QTNewGWorldFromPtr()
not really valid for passing back into the toolbox?

Regards,
Steve
