UDP Streaming Output

#1
We are already using CasparCG to produce OSG for a number of channels in a very traditional method with a BlueFish card. I've been asked to explore the possibility of adapting the installation to produce a UDP stream for our internal TV system. Following the limited amount of information on this I've created the following channel -

<channel>
<consumers>
<stream>
<path>udp://239.0.0.15:5001</path>
<args>-vcodec libx264 -tune zerolatency -preset ultrafast -crt 25 - format mpegts vf</args>
</stream>
</consumers>
</channel>

When i run the CasparCG server App. I get the following error message - 'No consumer factory registered for element name stream (casparcg.config: /consumer/stream[1]. turn on log level debug for stacktrace.

I initially tried using FFMPEG as the consumer, but i was able to produce a 5Mbit stream but VLC would not lock to it. Has anyone got any examples of this working? I'm currently using version 2.1.0 beta 2 - but i'm happy to change if it works better in another version.
