I am facing an issue when trying to stream an mp3 audio file to the Wowza RTMP server.

In one terminal window, I am using this command:

```auto
$ ffmpeg -re -i input_file.mp3 -c copy -f mp3 rtmp://ec2-xx-xxx-xx-xxx.compute-1.amazonaws.com/live/mystream

```

This is the output:

In another terminal window, I try to play the RTMP stream using ffplay:

```auto
$ ffplay -i rtmp://ec2-xx-xxx-xx-xxx.compute-1.amazonaws.com/live/mystream

```

This is the output:

[rtmp @ 0xb0e00bc0] Server error: Failed to play mystream; stream not found.
rtmp://ec2-xx-xxx-xx-xxx.compute-1.amazonaws.com/live/mystream: Operation not permitted
    nan : 0.000 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0

```

I am unable to fathom why I am getting the errors “stream not found” and “Operation not permitted”.

Just to compare, I tried streaming the audio file as an ‘flv’ stream like this:

```auto
$ ffmpeg -re -i input_file.mp3 -c copy -f flv rtmp://ec2-xx-xxx-xx-xxx.compute-1.amazonaws.com/live/mystream

```

This works beautifully. I can play it using the ffplay command in the other terminal without any problem.

Does the ‘live’ application on the server not handle mp3 streams? If not, can someone help me understand why the mp3 stream is failing with “stream not found” and “Operation not permitted” errors, while the flv stream doesn’t?

Thanks in advance!
