[gst-devel] sub part of a movie

[Mark Nauwelaerts]

The exception is most likely an effect of bug 
http://bugzilla.gnome.org/show_bug.cgi?id=540221, the fix for which may not be 
present in your gst-python (or otherwise another bug very much like it :) )

It can be worked around (IIRC) by adding the option --ignore-prop '.*sink.*'
(so it does not access the sink's property leading to the crash).

I also have some doubts about the chances for success of the pipeline
(e.g. no dam in it, entrans uses this element to direct the seek to ...)
Using a more "conventional" pipeline as exampled in the link mentioned below may 
be advisable.

Mark.
