Hello all,
I am part of a project team developing an internal video broadcast solution for periodic internal communications at my workplace (~3000 employees). A contractor provided our organization with this service on a one-time basis in January this year, now there is a desire to have it available internally on a full-time basis. Our main delivery target is Windows 7 desktop and laptop PCs (although BB10 + iPhone devices are a future possibility); we have both Flash and Silverlight plugins installed everywhere.
Based on what the contractor left behind on the servers we provided, it looks like they were doing the following (and other than terribly low audio levels, it worked great):
- encoding audio / video to an MPEG2TS stream on an unknown external device (we are looking to replace that piece with a laptop / capture card / software encoder)
- distributing to the majority of our LAN via multicast with Wowza 3.6 + Push Publishing add-on (playback via Wowza’s sample Silverlight player)
- providing a fallback to Unicast delivery for the few non-multicast enabled areas of our network (playback via Flash / JWPlayer)
- _both players are embedded in a web page (with full-screen support enabled) - and we would like to keep it this way if possible - i.e. no external QuickTime or Windows Media player window._

Hi Kevin, yes Wirecast with Wowza is capable of meeting your needs.
Using H.264 video and AAC or MP3 audio from Wirecast you will not need to use the Transcoder.
You can use the Push Publish feature of Wowza to deliver the streams across your LAN:

And here is a tutorial for using Wirecast with Wowza:

Hi Richard, is there any updates on this ? I need to do exactly as described by OP and I am kinda stuck with the multicast player solution. Silverlight is no longer an option, VLC is… VLC…, and Quicktime, anything else? OSMF is getting old and now unsupported.
The need for a web based multicast player is there, many big companies cannot do unicast for their internal communications. Any other ideas?
Thanks

The VLC browser plugin is an option that I’ve tested and which worked for me. The client system has to have VLC installed to have the plugin for this to work. I have tested on Windows only, and it should work in IE, Chrome and NN browsers:
```auto
Wowza multicast /w VLC Plugin
```

I didn’t work in my test, but as Quicktime player works for Wowza multicast it is possible the Quicktime plugin will work, and it might provide a better user experience with regard to plugin installation. However, it didn’t work in my test and I would be concerned about the differing Quicktime player support on Windows and Mac.

Kaltura’s Silverlight player seems to support multicast but I’m still trying to figure out its implementation. Does anyone have a copy of the old Wowza Silverlight player for review?

Hi,
We no longer provide the SilverLight Multicast player and we never provide the source code for it.
Although Kaltura may provide source code there may be additional patent fees associated with using it, as open source is not the same as patent free so if you are looking to use it please do take some legal advice.
Andrew.

Hi Kevin, are you using the Silverlight Multicast player?

Thanks for the links Salvadore - the setup is so deceptively simple it’s hard to believe there isn’t something missing. 🙂 In my case, there does seem to be though.
My pushpublishmap.txt entry is as follows:
myStream2={profile:“mpegts”, streamName:“myStreamMPEGTS”, host:“239.192.0.100”, port:10000, rtpWrap:false, debugLog:true}
The Wowza server is on my local network on 192.168.0.113, the Wirecast encoder is on 192.168.0.118.
I can see Wowza receiving the RTMP stream I’m generating with Wirecast, and Wowza appears to be sending out a multicast stream (I can play it on a test workstation in VLC using the URL udp://@239.192.0.100:10000).
To verify that my network can carry multicast traffic, I successfully originated a multicast stream on the Wowza server (using VLC as the source) and on the Wirecast computer (using its Quicktime Multicast output profile, and VLC as a player via an SDP file that I generated with Wirecast).
My remaining problem is that when I try to point the Wowza-supplied Silverlight player at the Wowza multicast, it produces the error:
ERROR: Error connecting to multicast stream: 239.192.0.100:10000
The relevant part of the HTML I modified is as follows:
I have disabled the Windows firewall on all systems for testing, it has made no difference.
Any idea where I need to look / what I need to do next?

Yes I am, but I overlooked the need to add entries to the Server.XML file (i.e. I did not read the instructions that came with the player :o). I will give that a try later.

It’s amazing what following instructions will do. I now have a working multicast Silverlight player, and also managed to get an RTMP OSMF player working.
I do notice that motion is a bit “stuttery” in the Silverlight player, but I can live with it for demo purposes.
Thanks for pointing me in the right direction.

Sorry to resurrect a dead thread, but it is now production implementation time in my environment. However - I notice that Wowza no longer distributes the Silverlight multicast player. Are there other browser-based options for playing the same type of multicast stream originated from a Wowza server?
---
Thanks for the code Richard - but pushing VLC Player to ~6500 workstations is not an option for me. Any other suggestions out there (other than using the Silverlight plugin that I archived locally)?
On a somewhat related note - what happened to [OSMF.ORG](http://OSMF.ORG)? I’m being directed to a “spa” website when I try to go there to get the OSMF player (compiled SWF). Is this component available elsewhere, or has it been replaced with a more modern alternative?
