How to receive multicast input

Wowza Streaming Engine
1

I am new to this technology. I have a task of streaming live TV channels (about 10) on the web. I have set up the server and am able to play the test stream.

All the 10 channels have unique multicast ip address and port. i have gone through the documentation and found that the streams have to be pushed to port 10000 (please correct me if i am wrong) but since my input feed is from multicast source, i am not sure how to achieve this. I am able to play the stream on udp protocol and the multicast ip using vlc player.

Would like to know the following :

  1. How to make wowza server to take feed from multicast source (:) or multicast group

  2. Do i require any addon package to achieve this

My version is 3.0.4. Any help from anybody will be highly appreciated. Thankyou in advance.

Take a look at this guide:

Hi Shyjur,

Let’s see if I can help get to the bottom of this. Do you know what the model/manufacturer is of the encoder that is streaming to Wowza? If so, you can look to the documentation/settings to determine exactly what the stream codec and parameters are. That is the key piece of information here.

Wowza is saying it can’t play the stream:

“[mp4a.40.33]: MP3 Audio: Audio is not MPEG1 Layer 3. May not be playable by Flash player.”

Many thanks for the quick reply Richard!!

I have gone through the article and have setup the media server as per the document. Now i can see something being received but am not able to play the same in the browser. The following is the logs for your reference.

I get the following when i try to play the stream using LiveVideoStreaming client :

INFO session connect-pending 106.51.3.233 -

INFO session connect 106.51.3.233 -

INFO stream create - -

INFO stream play mpegts.stream -

Please let me know if there is any configuration missed out.

Thanks in advance.

PS : Am able to add the live stream and receive stream using streammanager

Hi Randall,

I have got some info on the incoming stream. The video is mp2 and audio is AAC and not MP3. This being the case, do i need to transcode this for wowza to recognise the stream ?
