Hi there... I am doing a school project using Splicer and I have a question.

I know that I can use an ICallbackParticipant to get the current frame that is being rendered, using the IntPtr buffer from ProcessBuffer. But what if I have a 2 track composition and I want to get the frame from the track being rendered (ok, IntPtr buffer) and the frame from the track below?

I tried using IMediaDet interfaces from DES in ProcessBuffer to get it, but it gets too slow... it is possible to do it with Splicer, changing something in ProcessBuffer or somewhere else?
