Shoutcast Restream problem

Wowza Streaming Engine
1

Hi,

I create radio ports with Centova Cast and Shoutcast and i use Wowza Stream Engine version 4.0.1 to make restreamings. I follow all steps in the manual to config restream with Wowza and all works fine, but when the radio have a few minutes or hours, start to cut the audio, and some cases repeat a range of 30 seconds repeat and repeat, the only solutions that i have is restart the .stream when i do this the stream follow excelent, but after time we have the same problem again and again.

I don’t know what can i do, this wowza instalation is new, with a new server, in my old server all works fine but we change to this new server to have a better performance with hardware and bandwith.

What is my mistake?

I hope you can help me.

This is a copy of my application.xml /live

Thanks

I there, can you please provide a little more information.

What guide are you following? Is it this:

How to re-stream audio from SHOUTcast/Icecast

Are you noticing this behavior regularly?

What clients are you testing in when this happens?

You can try adding this property to the RTP/Properties container in the Application.xml file to see if it helps:

<Property>
    <Name>audioPacketizerAAC</Name>
    <Value>com.wowza.wms.rtp.packetizer.RTPPacketizerMPEG4LATM</Value>
</Property>

Lastly, this issue sounds like you are using a StreamType of “default” but I see you have it set to “live” make sure you are re-streaming to the correct application.

Hi,

If you are referring to total memory, that is a reflection of the total system wide memory usage, and not necessarily that which is used by Wowza.

Wowza makes use of the Wowza Heap allocation, which is only a part of that total memory usage shown.

Hi @salvadore thanks for your reply.

What guide are you following? Is it this:

How to re-stream audio from SHOUTcast/Icecast

– Yes, this guide i follow

Are you noticing this behavior regularly?

– Yes, this happend 1 or 2 times on day each 3 or 4 hours, when i restart the .streams the audio goes good.

What clients are you testing in when this happens?

– We have around 20 radios working on this server, radios using Shoutcast with AAC and restreaming with Wowza nothing more.

You can try adding this property to the RTP/Properties container in the Application.xml file to see if it helps:

– I’ll add this property right now i hope this resolve this issue.

Lastly, this issue sounds like you are using a StreamType of “default” but I see you have it set to “live” make sure you are re-streaming to the correct application.

– I don’t understand this, i Have set StreamType to “live” not to default and when we set the restream only use “live”.

Thaks again for your help.

Alex.

Another thing i see, is when the server have between 2 and 4 days uptime without restarts the memory goes up.

See this image of process.

I add the AudioPacketizer AAC and the problem persist, i add this module https://www.wowza.com/docs/how-to-enable-advanced-monitoring-and-resetting-of-mediacaster-streams

But nothing happen, the service is bad, the audio is cut :frowning: after 3 or 4 hours

Somebody have any idea what ocurre?
