Because I want my desktop to be broadcasted in my network I did the following:
- served an RTMP stream of the Windows Desktop using OBS (open broadcaster software) + NGINX with RTMP module;
   resulting URL: rtmp://192.168.1.21/app/live

Now inside MC I did the following:
- added this URL via this method http://wiki.jriver.com/index.php/DLNA#Connected_Media_-_Streaming_Web_Radio_via_DLNA
   to the library
- added the playlist where the URL is in to a DLNA server

Now when I try playing the stream via DLNA it does not work. Some DLNA clients say unknown filetype and others simply state it can't be played or even say nothing at all. Playing the video stream via DLNA fails.

Also tried to play the stream using Gizmo with no success. Gizmo remains in "Preparing..." and continously displays "Error communicating with server". Playing the video stream via Gizmo fails.

Playing the video stream directly inside MC using the exact same URL works fine.
Playing the video stream with VLC and the exact same URL works fine.

Open Broadcaster uses Quick Sync (H264) to encode the video. There is no audio stream present in the encoded stream .

Why does the described scenario not work? Any hints, suggestions?

It doesn't work because your DLNA client doesn't support RTMP.  MC only forwards URLs to DLNA clients directly.

Hardly any renderers support RTMP -- most rely (only) on HTTP ...

[masterjoe]

So... instead of simply forwarding the URL would it be possible for MC to re-wrap (and eventually transcode) the video using a suitable container format and its own URL? Because MC CAN obviously read the RTMP data and render it. So it should be possible to send it in a suitable format to other renderers?

That would ideed be nice

Out of interest did you try playing the stream in EOS to the local device?

Edit - Thinking some more it will not work in EOS either.  EOS does use MC to start transcoding streams then sends that stream but it is just for the ones under Television (inc webcams).

[masterjoe]

Well as you were asking... I made a test. And it is somewhat disappointing 
When opening the library entry EOS says: "An error occurred attempting to play the video."

As I said - MC can definitively play this RTMP stream when I play it in the desktop player (display view)!

This takes us back to:

It would be possible. But not soon ...
