Depending on the playback options you have chosen, such as Output Stream or Playlist (depending on OvenMediaEngine settings), Protocol selection (LLHLS or WebRTC), Certificate availability (TLS or Non-TLS), etc., a Playback URL of the Stream is displayed. You can <mark style="color:yellow;">play it through OvenPlayer or an external player using the Playback URL</mark>.

### Playback URL
