# Stream plugin
A stream plugin is (this might change in future) an executable binary or script that is started by the server for a specific stream and offers playback control capabilities and provides information about the stream's state, as well as metadata for the currently playing track.
The Snapcast server communicates via stdin/stdout with the plugin and sends newline delimited JSON-RPC commands and receives responses and notifications from the plugin, as described below. In upcoming releases shared library plugins might be supported as well.

## Requests
The following requests will be sent by the Snapserver to the stream plugin. Upon startup Snapserver will wait for the plugin's [ready notification](#pluginstreamready) to [query the supported properties](Plugin.Stream.Player.GetProperties). The controlling capabilities are encoded into these boolean properties: `canGoNext`, `canGoPrevious`, `canPlay`, `canPause`, `canSeek`, `canControl`.
If `canControl` is `false`, the server will not send any control commands to the plugin.
