+++ This bug was initially created as a clone of Bug #732294 +++

First of all it is too simple and does not properly implement the algorithm
from S377-1-2009c chapter 11.

Then there are the following issues in the simple implementation currently
- it assumes the index table segment position is somehow related to the
position of the media. This is wrong, all index table segments could also e.g.
be in the footer partition. (the segment->stream_offset field)
- the de-duplication of the index table segments only looks at the start
position. Look at ffmpeg for a better implementation. Ideally one would parse
all the segments into a full, internal representation that combines all the
segments.
