Our church is using Wirecast 4 for several different purposes. We're currently using it to record our service and to stream our service to the web for those unable to attend. We'd also like to use it to stream to TVs spread around the church (in the Atrium, nursery, and perhaps to the gym for over-flow) but I have been unable to get our Amino A130s to connect directly to the wirecast stream.

I HAVE been able to get a video stream going by using VLC to run as middleware to re-encode the stream. I use the following settings in Wirecast:

LAN - Windows Media 9 preset
destination network
pull from server port 1850

I can then set up VLC to restream using:
Source - mms://10.0.0.3:1850
Destination -
UDP (Legacy)
Address: 235.0.0.1
Port: 1234
Transcoding: Video - H.264 + AAC (TS)
(ed: I don't know what the (TS) means, but it's required. H.264+AAC (MP4) does NOT work)

THEN, I set the amino to connect to udp://235.0.0.1:1234 and the stream works.

The problem is, it's a LOT of resources being used and it's causing problems all over the place. What I'd like to figure out is a way for the Amino to pull the stream directly from Wirecast. I don't think Amino can read WMV but I know it can decode MPEG4 as shown above.

I've tried setting up Wirecast to use MPEG 4 + AAC but it doesn't work in any format that I've found. I wonder if it's the encoder that the built-in streaming uses. I THINK Wirecast uses Apple's Darwin server. I DON'T think Amino A130s can decode that.

I'm just wondering if anyone else has come across this problem or figured out a way around it?

I'm not sure what the limitation are of the Amino A130 IPTV STB but Wirecast can stream to servers that can handle mms, rtsp, rtmp. See if the Amino can handle one of the other protocols

it does a form of mms, but it seems limited to legacy UDP. I haven't found a way to replicate this directly from wirecast. It WILL take an H264 + AAC (TS) stream, but I can't figure out how to send out a (TS) stream either.

it is SUPPOSED to handle rtsp; however I haven't been able to get it to accept one from ANYTHING at this point.

I'm working to try to get updated firmware for the box, but getting a support account with them is one of the most convoluted processes I've ever come across. I THINK that is why the rtsp stream is failing, but I can't be sure.

I haven't tried an rtmp stream. I don't remember seeing any documentation for that, on either end.

We're looking at putting a Wowza server in between, and that is where we're intending to go with final product anyway; but until we get the hardware/software stood up I've been trying to work something out. I'm hesitant to try to run Wirecast and Wowza off the same platform due to resource requirements.

I won't recommend wowza and wirecast on the same machine. Both are very CPU intense and the other side is that all connections from the users would come to one machine, that encodes and distributes. Not a good idea. You can use Wowza on Amazon with small costs. Runs perfect.
If you want to stay on one computer I can think of wirecast and a second Monitor for output the mix. Use a Multicast Screen Streamer for streaming to the LAN with Multicast. Therefore the number of users is irrelavant. And stream to a Wowza on Amazon for public/mobile viewing.

Hi All

I am a newbie to wirecast and considering using it but would like to know if the following is possible

Will wirecast stream mpeg4, if I use the inbuilt darwin server. I want to stream to a wowza server in the network which will in turn stream mpeg4 using http live streaming to a set top box which support HLS stream

Feedback welcome

Thanks
Hollor

Just stream directly to wowza. You won't need the build in streaming server

Yes, there's no reason to use the darwin server if you're going to Wowza. Wowza will be able to take the stream and send using multiple methods.
