Tim,

Have you looked into using Quartz Composer and QCView to accomplish what you want?

Another option is dynamically creating an interactive QuickTime movie with multiple video tracks. These tracks can be "programmed" to respond to mouse clicks, which could alter each movie's geometry - if you need to have the user "lay out" the movies in relation to one another.

Also, is their some constraint in your application that forces you to show all the movies in one view?

later,

douglas

Hi everyone, I hope someone can point me in the right direction, I've
got that flailing feeling at the moment...

I am trying to write an application to play multiple movies and
display images simultaneously on the same View

The first thing I tried was declaring my own view which created
QTMovieView subviews that could be dragged around, but after reading
these lists found out that overlapping views is not a Good Thing to be
doing (and you cannot draw over the top of QTMovieView very easily to
show resize handles, etc

So I am now trying rendering movies/images etc to OpenGL textures, and
displaying them as OpenGL quads (like the QTCoreVideo101 sample, and
the LiveVideoMixer sample).

Is this the way forward?

I keep crashing head first into problems, and don't have the
experience to tell me if it is worth going forward...

It would be great if someone could tell me if I am on the right path,
or if there are other avenues I should be looking into and
considering..

Thanks for any help/ideas/new directions you can give!

Tim

PS:  Sorry if this is a regularly repeated question, I had a quick
look through the search, but couldn't see anything directly relating
to my problem :-(
