[M4IF Technotes] BIFStext

[Karin Liebmann]

Hello everyone,
I have a question concerning BIFStext...
I would like to know if BIFStext is part of the MPEG-4 standard.. because I didn't find any statement about it in the specification documents from the MPEG homepage.
The standardized methode to create a mp4 szene with 3D, video and audio content would be:
3D files as a x3d file - converting the x3d to xmt - including video and audio - converting to a mp4 scene..
the methode I used with my project was:
3D files as a vrml file- converting the vrml file to BIFStext- including video and audio streams- converting to a mp4 szene with the help of the mp4tool..
Is it right that this methode and the BIFStext is not MPEG-4 standard conform? But it works!
Is BIFStext a solution created by ENST??
I used the second methode because I didn't find enough informations about converting X3D to XMT...
Are this the only two methodes to create a mp4 scene?
I would be really glad to hear from someone of you!
Thanks very much in advance!
regards,
Karin
