Required Header

#include <media_controller_server.h>

Overview

The Media Controller Server API allows you to send the playback info(mc_server_set_playback_state(), mc_server_set_playback_position), or the metadata(mc_server_set_metadata()). and to receive the custom command(mc_server_set_custom_command_received_cb()), to update the status information on the latest server(mc_server_update_playback_info, mc_server_update_metadata), or to create/destroy the handle(mc_server_create()/mc_server_destroy()).
