[M4IF Technotes] 3D BIFS example

[mart]

Hi Jim,
The Osmose player is built upon the IM1 2D Player from the MPEG-4  
Systems Reference Implementation. This means it supports only 2D BIFS  
Nodes. Envivio TV surely doesn't support 3D Nodes either.
You can though grab the Systems Reference source from  
http://www.iso.ch/iso/en/ittf/PubliclyAvailableStandards/ISO_IEC_14496- 
5_2001_Software_Reference/systems.zip and compile it yourself. I have  
done this and it actually works rather well for testing purposes,  
although I didn't manage to get any scenes with audio (neither g723 or  
AAC) running, which should actually be supported. (If anyone can help,  
I'd greatly appreciate it)
One more hint: If you are using the 3D Player from the Reference  
Software with mp4tool from ENST for converting .bt files to .mp4, you  
have to use the "-preCOR1out" option, as opposed to the newer (2D-)  
Osmose Player, where you don't use it.
Hope this helps...
