[LINUX] Forcibly bring out DLNA with ReadyMedia + Reverse Proxy

Overview

I tried to bring out DLNA when using the audio media at home outdoors. The environment is limited, but I managed to do it, so a memorandum.

• DLNA does not include LocationFree. The response speed is included in the specifications, and it is an act that is not actually permitted.

Environment configuration and setting value example

Tools used

• Domain (Dynamic DNS or regular purchase)
• Server
• Linux (Cent OS)
• Apache Httpd
• mod_substitute
• ReadyMedia (miniDLNA)
• Tinc VPN
• Client
• foobar2000 (android / iOS)

procedure

Procedure (1) Domain setting

Set the association between the global IP of Server (2) and the host name. (Domain registrar, DDNS service site, etc.)

Step (2) [Server (1)] Build ReadyMedia

Install ReadyMedia on your local server and build a DLNA server. (The construction method is omitted because it is 2 ^ 10 decoction)

Step (3) [Server (1), Server (2)] VPN construction

Because it is a reverse proxy, the purpose is to enable mutual communication between servers. Not required if both servers are on the same network. Also, VPN construction is possible other than Tinc VPN, so it is omitted. (I mean, it gets longer when I write it ...)

Step (4) [Server (2)] Reverse Proxy settings

The main part of this article. Set Reverse Proxy on Virtual Host. DLNA communicates with the server in XML, Because the full path to the content includes the IP address is returned You cannot reach the media through the Reverse Proxy. Therefore, replace the IP described in XML with the host address. Since the communication between the servers is via VPN, the replacement source IP is the VPN IP.

apache:/etc/httpd/conf.d/httpd-vhosts.conf

<VirtualHost *:80>
  ServerName dlna.mydomain.org

  AddOutputFilterByType SUBSTITUTE text/xml
  Substitute "s|192.168.5.2:8200|dlna.mydomain.org|i"

  ProxyRequests Off
  ProxyPass / http://192.168.5.2:8200/
  ProxyPassReverse / http://192.168.5.2:8200/
</VirtualHost>

terminal

systemctl restart httpd.service

Step (5) [Client]

Listen using the smartphone version of foobar2000.

Impressions

• Thank you because there is no way to play media files character by character over the network.
• Since playlist files can be used with ReadyMedia, it is nice to be able to create playlists on a PC and run them down.
• Since foobar2000 is the only client that can add DLNA by URL, there is no choice.
• However, the GUI of foobar2000 is too bad, so it is delicate as a DLNA client in the first place.
• It is not possible to turn off the playback stop due to disconnection of BT or headphones. ..
• I want the left and right swipes to be song selection (previous song, later song),
• Cannot apply https or BASIC authentication,
• If you want to improve security, replace it with localhost by port forwarding?
  (Do you want to go that far?)
• Can you still use it compared to BubleUPnP?
• If you feed the song before loading, there is a stupid bug that the screen and the actual song are out of alignment, so ...
• The UI doesn't change much ...
• Isn't Plex all right?
• However, I feel that it was easy to introduce with a small amount of resources.
• For the time being, it looks good to just digest the 500 songs I bought at the flash sale the other day.
