Could you please explain this :

Chances are Shoutcast will have a similar player or a JS API to bind the buttons with their strems.

Where can i check if shoutcast have this or not ? whats is JS API anyway ?

Thanks.

You can refer our discussion to the Shoutcast DEVs.

An API, roughly put is a way to access their services, eg. a script (in JavaScript - JS) that plays their streaming service.

How do I use the player with shoutcast ? has not been resolved ?

Radiojar is supported by default.
Shoutcast has to be a custom implementation.

You need to ask Shoutcast if they offer a HTML/CSS player that you can include in a K2 Tools module.

Would you please explain me how can do it? I need use Shoutcast stream in my site, but I don't find (understand) what must I do :(
Thank you.

You need to ask Shoutcast if they offer a HTML/CSS player that you can include in a K2 Tools module.

Ask them if they do.
Then all you have to do is paste that code inside a K2 Tools module and select the custom code functionality.

You can also duplicate the already present module in order to keep the same position.

I buy my membership to use radiowave by the look and everything is included, now you say that you necessarily have to use radiojar to keep everything I saw in the demo, because if I change the player im changing the template, but i like the template like i sow in demo obviously, and they must know that you are looking at radio template you usually already have a streamming! if i need to change look and feel this template dosnt work!

All the modules are available as K2 content modules as well.
As for the player you can port it to support Shoutcast/ Centova etc, you can use your own player in the available module positions.
