[Mp4-tech] IBM BatchXMT file format

[Michelle Y Kim]

Although I will be more than happy to discuss this issue here,  t would be 
more appropriate, in my view,  if you could post this question on the IBM 
alphaWorks discussion forum due to its specific technical nature.  But the 
IBM team will send you a private response on this one.  Thank you.

        Subject:        [Mp4-tech] IBM BatchXMT file format
I am playing with the IBM BatchXMT tool for creating mp4 files from 
XMT-O scene descriptions. In the samples I downloaded the XMT files 
refer to .cmp video files. I tried to include one of my own mp4 files 
(created from qt pro), but without success. Do I need to convert them 
to the .cmp format, in that case; what is the .cmp file format, and how 
do I convert to it?
I also have problems scaling and rotating videos with the same tools. I 
have tried the following code:
<video dur="media" src="../multimedia/videofile.cmp">
     <transformation>
     <animate  id="sdlfkj"   dur="5s" repeatDur="indefinite"
         attributeName="rotation" from="0deg" to="180deg" 
calcMode="linear" />
     <animate  id="cmov2"    dur="5s" repeatDur="indefinite" 
attributeName="scale"
         from="1.0 1.0"     to="5.0 5.0"/>
     </transformation>
</video>
The same code works for rotating circles and rectangles.
Regards,
Andreas
