The [FFmpeg documentation](https://www.ffmpeg.org/ffmpeg-protocols.html#rtmp) suggests this syntax:

```auto
rtmp://[username:password@]server[:port][/app][/instance][/playpath]

```

However, this will give you an “Problem accessing the DNS.” error when trying to connect to the Wowza server.

In [this thread](http://community.wowza.com/t/-/37912) it is suggested to use Wowza SecureURLParams instead of RTMP authentication, when streaming from FFmpeg.

Is it still not possible to use FFmpeg with RTMP authentication?

Hi,

[SecureURLParams](https://www.wowza.com/docs/how-to-secure-publishing-from-an-rtmp-encoder-that-does-not-support-authentication-modulesecureurlparams%28ModuleSecureURLParams%29) is the only way that works currently

with FFMPEG.

Hi,

The following will actually work in windows without the need for secureURLparams:

```auto
 -f flv "rtmp://serveraddress[:port][/app][/streamname] flashver=FMLE/3.0\20(compatible;\20FMSc/1.0) live=true pubUser=myuser pubPasswd=mypassword" 

```

For what is worth, it DOES work on Linux. In Windows appears that the URL parsing scheme is not the same and it’s not working.
