No this is not possible, unless the VJ software passes its frame
buffer as an image to a QC composition
Exactly how would you pass the image if the VJ software is already
rendering into a PBuffer?
can you share images between programs this way without having to
read back from the graphics card into main memory?
pBuffers can be passed between various graphics technologies: if
the VJ app produces a CVOpenGLBuffer (i.e. CoreVideo wrapper around
a pBuffer), it can be passed to QC
