Long: `Run a DLNA media server for media stored in an rclone remote. Many
|
|
|
|
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.

2022-06-19 19:18:14 +02:00
|
|
|
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.
