multifilesink - how to interpret values sent via bus message?

[Nezer Zaidenberg]

Hi Ralph,

I think what you need is non-linear editing. There is a project called
gnonlin which is a part of gstreamer and does just that. It can cut a movie
into multiple parts in any manner you like.
If you are only using it for one dvd you could also check out VLMC
(VideoLan Movie Creator) which has a nice gui for non-linear editing.
After you do this, you get multiple movies (as the parts of the original),
which you can query (using gstreamer for instance) for duration.

If this still doesn't help, and you want to pursue the original solution,
could you post your pipeline for reference?

Best regards,
   Nezer
