I send multicast RTP stream , I received it by wowza , when I add a new stream from the stream manager , I receive the followings msgs.

The video track must be h.264 (mpeg4 part 10). Mpeg2 is not supported, except for decode by the Wowza Transcoder

Transcoding will have more or less of an effect on all 3 of those metrics.

Hi ehuman,

First see the Transcoder tutorial: https://www.wowza.com/docs/how-to-set-up-and-run-wowza-transcoder-for-live-streaming

I have not tried your exact configuration, but I believe you would follow a similar process as the MPEG-TS tutorial: https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder

In other words, you would create a stream file called myStream1.stream, for example, and that file would contain: rtp://239.255.1.1:5004. This would then need to be started using the StreamManager.

Then look to the first link I posted in the “Template Configuration” section you will see: “Where [stream-name] is the name of the stream you are sending from the encoder to Wowza Server. For example if the incoming stream from the encoder is myStream then the transcoded streams will be myStream_360p, myStream_160p and ngrp:myStream_all.”

So then in your case the stream name would be “myStream1.stream” instead of “myStream”.

Then you could play a single transcoded stream in Silverlight with something like:

http://[wowza-ip-address]:1935/live/myStream1.stream_160p/Manifest

Make sure that your transcoder template Video and Audio codecs are set to H.264 and AAC respectively. Playback using the transcoded streamname:

http://[wowza-ip-address]:1935/live/test.stream_160p/Manifest
rtmp://[wowza-ip-address]:1935/live/test.stream_160p

thank you , is there any negative points for doing the transcode on the server ( i.e :video quality , delay in live streaming , wowza server performance , etc )

please do you have any instructions about how to transcode it .

the MPEG-2 channels stream as the following :

rtp://239.255.1.1:5004

rtp://239.255.1.2:5004

rtp://239.255.1.3:5004

so how can i transcode all this channels , your effort is highly appreciated :slight_smile:

I tried to do all the instructions , this is the output the i get :

Note: if i change the source from rtp://239.255.1.3:5004 to udp://239.255.1.3:5004 i got another result:

i tried to play it through rtmp://myip/live/streamname

please advice , thanks :slight_smile:
