Overlaying video and sprite tracks in QuickTime ?

Overlaying video and sprite tracks in QuickTime ?

Overlaying video and sprite tracks in QuickTime ?

Hi all,

I'm a Quick Time newbie. I'm trying to write a program that authors a QuickTime movie.

The movie consists from a video track and a sprite track.
I need to overlay them so they are played at the same time so I have a video on background and some sprites on the top.
Both tracks work separately, but I can not overlay them to play simultaneosuly. Using SetTrackLayer() I set the layer of video track to 100 and layer of spite track to 0.
I set the time scale and track offset the same, but this dos not help. referencing those trachs with AddTrackRefernece does not work either. I also need to restart the video track from beginning when it finishes.

Any suggestions ?
