[Mp7-tech] How to generate MPEG7 streams in .mp4 files ?

[james engwell]

Hello there,
I am contacting you on behalf of a company called versatile delivery 
systems, we are trying to get some clarification in regard to embedding 
mpeg7 xml in mpeg4 files.
Over the last year we have developed a video tagging system. We wish to 
be able to generate an MPEG7 stream to carry the metadata, but have 
been unable to find out how to do this, as the following snip from an e 
mail conversation with Jan devos of the 3ivx company shows:
>> We are finding it very difficult to access any expertise in this

If there is any help you could give us to help us get to the bottom of 
this problem, your feedback would be much appreciated
Yours sincerely
