           Summary: thoggen failing to encode a dvd due to gstreamer plugin
                    problem
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED

Please describe the problem:
When using Thoggen to encode a particular DVD, I get a very large
timestamp from the video pad every time at the same place every time.
I've traced this to the sending of newsegment events from the mpeg2dec
element, which get passed to videorate, which them emits huge timestamps.
Thoggen then stops encoding.


Steps to reproduce:
1. Encode a DVD with Thoggen (my test case is Princess Mononoke)
2. Wait till 310 seconds of it are encoded
3. Watch the encoding stop


Actual results:
The encoding stops

Expected results:
The encoding goes on till the end of the title

Does this happen every time?
yes

Other information:
If I comment out the sending of newsegment from mpeg2dec, Thoggen goes
on till the end of the title, but at the place where it would have stopped,
I get a dozen or so seconds of crackling audio, which seems to be more or
less what it should be if it was not crackling. After it recovers, the sound
is still in sync.

I'm afraid I have no patch for it. I do not know whether the problem lies in
mpeg2dec, videorate, anything else, or even the dvd itself.
