audio is not working for live stream. (video is working)

Pradeep_Nethagani · April 19, 2013, 2:00pm

Hi

We are trying to setup a live stream. Video is working fine but audio is not working. I have verified that encoder is publishing the stream correctly (Live preview available in the encoder to check the output stream). We are streaming the content through wowza and wowza is not playing the audio, But the video is working fine.

We have setup the live stream using sdp file

jwplayer(“player”).setup({

‘id’: ‘playerID’,

‘width’: ‘600’,

‘height’: ‘350’,

‘provider’: ‘rtmp’,

‘streamer’: ‘rtmp://[Ip address]:80/live’,

‘file’: ‘cds.sdp’,

sources: [{

file: “rtmp://[Ip address]:80/live/cds.sdp”

},{

file: “http://[Ip address]:80/live/cds.sdp/playlist.m3u8”,

provider: ‘video’

}]

});

this is the code which we are using. Any thoughts on what could be the issue. I have verified the ports on audio. they are open to UDP. The console shows the following when i start streaming in the streammanager with the sdp file

Those lines show that no audio is being packetized (a/v/k:0/299/10) . Can you look above that, where packetizing begins and look for the audio related lines. The packetizer logs messages with details about the codec. It is probably not supported.

Strange, audio codec looks okay, but never gets packetized

What is the source? What version of Wowza are you using?

Can you play the source directly in VLC? Is the source on a public IP?

Richard

So what is the broadcaster, the source? Do you have a rtsp link to that source that we can test? If so, send email to support@wowza.com that include a link to this thread and the rtsp url of the source that we can try re-streaming.

right now i plugged in my iphone to play some audio files for the test purpose. I could play the live audio through the rtsp link given by the broadcaster (In VLC player–> “Open Media Stream” give the rtsp link there). But I am not able to play the audio using wowza.

This is the entire log
