restream more than one radio channel (http) using wowza

hello,

how can I restream or broadcast more than one radio channel using (http) , the source of the radio channel is (http) and i want to do live streaming for this channels , and what is the appropriate bit rate for audio streaming . , thanks for your support :slight_smile:

Hi

There isn’t a correct bitrate for streaming audio only, AAC normally comes at 56 kbps and mp3 comes in around 96 kbps - 128 kbps.

Source -> Wowza -> Client

Take a look at this link to help you,

Wowza does not support mms. I have been able to use VLC following the transcode examples at the bottom of this guide:

https://www.wowza.com/docs/how-to-use-vlc-as-a-live-stream-encoder-with-wowza-media-server-mpeg-ts

Just replace the rtsp url with the mms url in the first example in the note.

You would have to use the documentation and support resources for the 3rd party transcoder you are using. That being said, the Wowza examples have “scale=0.5”, which halves the resolution. You can set this to “scale=1”.

Hi

You can pull as many streams as your hardware can cope with, when a client connects they will get that stream.

Did you read through the link I sent you above?

How many streams/channels did you have in mind?

Hi

You have an Application called “live”

Take a look at this link,

https://www.wowza.com/docs/how-to-re-stream-video-from-an-ip-camera-rtsp-rtp-re-streaming

Create a text text file called mycoolstream.stream in the directory called /content/ as stated in the link above.

In the /conf/ directory you will see StartupStreams.xml this allows you to pull a stream into Wowza when Wowza starts.

E.g.

live/definst

rtp

mycoolstream.stream

If you set to point at the .stream file with the radio station details in that you want the content from (the source) Wowza will pull that stream.

Repeat this process for each stream/channel you wish to publish.

Now that Wowza is pulling the steam, and the new stream is called “mycoolstream.stream”, when clients connect to your application (live) and stream (mycoolstream.stream) they will get the radio station stream you are pulling to Wowza.

If you change to this:

live/definst

rtp

mycoolstream2.stream

You will have another stream into Wowza and you get another steam/channel in the same application called “live” called “mycoolstream2.stream”.

You clients will connect to [Wowza-ip]/live/mycoolstream.stream or [Wowza-ip]/live/mycoolstream2.stream

Hi

No you can’t re-stream the mms stream through Wowza.

Jason

thanks for your relpy , is it possible to pull an RTSP stream or MMS stream then stream them again , and how many channels can I receive ?

thanks again

yes i have read it , I have around 20 channels , I need to pull the channels from RTSP stream then restream them through my server , coz i need to connect them with analytics software , could you please provide me with any example that describes how can I restream more than one RTSP channel . thanks :slight_smile:

thank you so much :slight_smile: , is it possible to restream (mms) stream ? , do I have to use same method ? , please note that i don’t have the encoder , i only have the mms link so how can we restream it .

many thanks :slight_smile:

I have read some articles in the forum about restreaming mms , do you have any additional info about this or do you have any updates ways to do that , mms or mmsh or http , thanks in advanced.

thanks Jason H , and a special thanks to rrlanham :slight_smile: , but now i have a little problem , the problem is regarding the mms (radio channel ) , after the transcoding the quality has reduced , so how can I transcode the mms stream with the same quality , thanks to all of you guys :slight_smile:

now I’m using VLC as mentioned in the example , but there is a different between the source and wowza streaming quality , i tried to change the scale to 1 it better but still lower than the source, so what is the major parameters that should be similar between the source radio channel and our transcoding script ( i.e : bitrate , scale , etc . . )
