I am having a hell of a time getting this UDP stream to get ingested. If I publish as rtmp, it works fine, but a udp URI just doesn’t work 1. I create the stream: ```auto ffmpeg -re -i "myclip.mp4" -c:v copy -c:a copy -vcodec h264 -f mpegts udp:wowza-server-address:10000 ``` 1. I turn on the stream file, which contains: ```auto udp://0.0.0.0:10000 ``` 1. I wait for something to happen… Somehow, my stream isn’t hitting the .stream file, which claims to be “active” but I can tell from monitoring that nothing is coming in. Any ideas? -Mike ---

Hi Mike, You do not mention starting the .stream file. You can use [StreamManager](https://www.wowza.com/docs/how-to-use-stream-manager-in-wowza-media-server-3) or the Wowza Manager to start a stream, or add it to [StartUpStreams](https://www.wowza.com/docs/how-to-start-streams-at-server-startup) and re-start Wowza to start pulling the stream. You will use MediaCaster type “rtp” to start these streams by one of the methods above. When you do that you will see a publish event in the logs, and info about the connection and stream, or problems connecting to the stream. Richard ---

You are using the RTMP port. You want to use a port like 10000 as [shown in this article](https://www.wowza.com/docs/how-to-use-ffmpeg-with-wowza-media-server-mpeg-ts%28MPEG-TS%29). Make sure the UDP port you use is open. Richard ---

Hi, You may need to specify the actual IP address in the stream file for the EC2 server, instead of 0.0.0.0 I would try both internal and external IPs as well. And of course ensure that port 10000 is open in your EC2 security settings. You can also post results of the log section you referred to, to help troubleshoot. Daren ---

The logs show the stream is published, and every 30 seconds unbinds and rebinds it (dont know if this is normal). However, no signal that the data is getting to wowza at all. ---

Thanks! 1. I’ve tried inputting by source IP address also, to no avail. 2. I checked the port externally with network tool, appears to be open. Also, I can use the same port successfully with rtmp come to think of it. 3. From error log, at startup (I changed the port to 1935): ```auto ERROR server comment 2014-06-13 05:19:26 - - - 2.431 - - - - - - - - HTTPUtils.HTTPRequestToByteArray : java.io.FileNotFoundException: http://169.254.169.254/latest/meta-data/product-codes ``` 1.

Also, here is the ffmpeg command I’m using to do the test stream (works when I do rtmp): ```auto ffmpeg -re -i "testFileName.mp4" -vcodec libx264 -tune zerolatency -b 900k -f mpegts udp:[WOWZASERVERIP]:1935 ``` ---

Stream seems to not be binding to the port. Any ideas?
