ok now it becomes strange.
i try to "download" the stream under windows with rtmpdump. My tought was, that this has something todo with the windows implementation...
Surprisingly all works well. Even with no additional parameters given rtmpdump was able to download the stream. Applied command:
Code:
rtmpdump.exe -r rtmp://ondemand.flash.zdf.newmedia.nacamar.net/zdf -y mp4:/zdf/data/quicktime/zdf/10/11/101112_hsh_hsh_vh.mp4 -o test.mp4
ok at this point i take the current librtmp and replace the "old" one from XBMC (since i use dharma4 this was useless)
after this doesn't had an effect i increase the LOG-level of xbmc. Here it is:
PasteBin-Log
worth mentioning: xbmc/libtrmp is able to establish the stream-connection. But then, if the stream-media should be startet, the followin happens:
instead of requesting "mp4:/zdf/data/quicktime/zdf/10/11/101112_hsh_hsh_vh.mp4" the following line appears.
Code:
SendPlay, seekTime=0, stopTime=0, sending play: w4LOR=blue]0[/COLOR]) Items - Page ([color=blue]1/1[/color])
it seems that the "PlayPath" Variable isn't correct pasted into the RTMP context...
here is my default.py for this testing:
Code:
import xbmc, xbmcgui, xbmcplugin,xbmcaddon, sys, urllib, os
xbmcgui.DialogProgress();
listItem=xbmcgui.ListItem("Test");
listItem.setProperty("PlayPath", "mp4:/zdf/data/quicktime/zdf/10/11/101112_hsh_hsh_vh.mp4");
#listItem.setProperty("PageURL", "http://www.zdf.de/ZDFmediathek/hauptnavigation/startseite/#/beitrag/video/1188544/heute-show-vom-12112010");
#listItem.setProperty("SWFPlayer", "http://www.zdf.de/ZDFmediathek/flash/0003/Main.swf");
xbmc.Player(xbmc.PLAYER_CORE_DVDPLAYER).play("rtmp://ondemand.flash.zdf.newmedia.nacamar.net/zdf",listItem)
xbmcplugin.addDirectoryItem(handle=int(sys.argv[1]),url="rtmp://ondemand.flash.zdf.newmedia.nacamar.net/zdf",listitem=listItem,isFolder=False)
xbmcplugin.endOfDirectory(int(sys.argv[1]))
EDIT:
i quick checked it under linux Dharma Beta 4. The same default.py above leads to the following line:
Code:
INFO: SendPlay, seekTime=0, stopTime=0, sending play: mp4:/zdf/data/quicktime/zdf/10/11/101112_hsh_hsh_vh.mp4
In the windowsbuild something goes wrong with the "Parameter-Parsing". Seems some pointer is wrongly initiated.
I'm back 
I started this thread.. After over a year, i'm sitting back on this addon. i (thx mighty_bombero) tried to get it work with the external librtmp under 9.04 - but refused, because this was not my intention of a simple plugin. So now i updated to dharma/ubuntu - and i#ve seen, that librtmp is fully integrated. is this true now?
It seems, they#re using now .f4v instead of .flv (older videos are present in flv..) so - these are the example-data from the site and from the xml:
