Looking for a way to update metadata without playing #45

Would it be possible to enable a way to receive metadata without actively playing the audio stream?

I need a simple page displaying data on the current track from my server, to be displayed as a widget on a livestream. For this to work the widget must be always active without any input from the user. This requires forcing some sort of autoplay right now, which is blocked by the chromium based browser being used, meaning no metadata event is received. I've tried setting audioElement: null when instantiating the player but it did not have the desired effect.

Thank you for your work.

You can do this using the /status-json.xsl endpoint on your Icecast server https://icecast.org/docs/icecast-trunk/server_stats/ If you really want to, you can pull the metadata from the stream using this library; however, I would not recommend this if the client isn't playing the audio.

That's the issue, I cannot. Only artist and title metadata appear in /status-json.xsl all other ogg tags are missing, but your player is able to retrieve them.

You can use icecast-metadata-js instead of using icecast-metadata-player to accomplish this. You will need to fetch the stream, send the response into IcecastReadableStream, and then when the first onMetadata updates is called you can use the metadata and abort the fetch request. Simply put this code in a setInterval to repeat these steps.

Eshaz: could you please provide a short example in javascript for the following example:

Im sure many users could benefit from this. Thank you!

@lexterror I put an enhancement #63 that will cover this. I'll just make this a part of this library as a separate module.
