[M4IF Technotes] MaterialKey

[Danilo Tromp]

>- Is there any reference code sample available that shows a MaterialKey implementation 

It is not a reference sample, but it is a working sample. Take a look at it at 
 http://www.mpeg4.nob.nl/NOBMaterialKeyNode/ . If you want the source of the scene you can email me (or just type mp4tool -bt NOBMaterialKeyNode.mp4 :-). 
As you will see the sample does not really loop smoothly (Some people don't see it looping at all!). If you have suggestions about how to set it to loop more subtle, feel free to comment.

There is a rumor going around (.) that television as we know it is soon to be swept up and utterly transfigured by some digital-age thing they're calling interactivity. Pay it no mind. Television has always been interactive (.) Interaction lies at the heart of television as a cultural form - and always has. (.) TV would mean nothing without the active, organizing affections of its viewers; we shape it at least as much as it shapes us.
