+devices, such as the Xbox and PlayStation, can automatically discover this server in the LAN
+and play audio/video from it. VLC is also supported. Service discovery uses UDP multicast
+packets (SSDP) and will thus only work on LANs.
+
+Rclone will list all files present in the remote, without filtering based on media formats or
+file extensions. Additionally, there is no media transcoding support. This means that some
+players might show files that they are not able to play back correctly.
