multifilesink - how to interpret values sent via bus message?

[Ralph Heinkel]

Hi,

I'm (successfully) splitting a video from a DVD into separate files 
using 'multifilesink', by splitting at every new key frame.
The command I used is shown below.

What I need to do is to keep track of the produced files, and in 
particular I'm interested to get timestamp (when the file was 
produced) and duration of the individual files.
However when looking at the messages produced by multifilesink all 
junks seem to have identical durations, offsets etc (of absurd high 
values). Also the timestamp is just increasing in discrete steps. And 
this is even though all junks have slightly different sizes (around 
10secs +/- 1).

Can anybody help? (I'm a bloody beginner with gstreamer, so please 
help me with 'basic' explanations ;-)

Thanks a lot,

Ralph

PS: I'm using gstreamer 0.10.35 on legacy opensuse 12.1 on a 32bit 
machine.

My call:

gst-launch -m dvdreadsrc title=2 ! multifilesink next-file=2
            location='m-%05d.ts' post-messages=true


The log:
