gdp payloaded capture of RTSP ASF stream

First few bytes of the stream attached as gdp-payloaded capture, reproduce with:

GST_DEBUG=asf*:5 gst-launch-0.10 filesrc location=livwms-europarl-europa-asf-rtsp-head.gdp ! gdpdepay ! decodebin2 ! fakesink -v
Comment 1 Vincent Penquerc'h 2011-12-09 13:35:36 UTC 
As far as I can tell, the desync occurs after reading a "padding" chunk.
The code looks like it skips hte right amount of bytes, and there does not seem to be a valid looking chunk before or after the supposed end of the chunk, so it doesn't look like some off by some smallish offset.
The header is supposed to contain 7 high level chunks, and only 4 are found at the time the desync happens.
Comment 2 Tim-Philipp Müller 2012-01-06 12:10:39 UTC 
The stream was captured via http://www.europarl.europa.eu/ep-live/de/plenary/video?event=20111130-1500-PLENARY_SESSION&vodtype=Live
Comment 3 Nicolas Dufresne (ndufresne) 2017-11-27 01:40:26 UTC 
Seems very unlikely we'll be able to fix or even makes a new capture of this one, am I right ?
Comment 4 Tim-Philipp Müller 2017-11-27 09:38:17 UTC 
Why do you need more than the capture we have? IIRC the problem was that a packet in the asf header was missing or messed up and then it bails out during header parsing or somesuch, but I might be making this up.
Comment 5 Sebastian Dröge (slomo) 2017-11-27 09:46:30 UTC 
IIRC what happens is that the first packet from rtspsrc gets dropped somewhere and never arrives in asfdemux. There's another bug about that.
