[Plugin / Beta] DLNA Renderer Filter – hide selected DLNA devices from “Play on”

[Marcidarci 6]

Hi everyone,

I would like to introduce DLNA Renderer Filter, a small Emby Server plugin for users who have DLNA/UPnP renderers that they do not want to see in Emby's Play on device list.

What it does

The plugin detects the DLNA/UPnP MediaRenderer devices discovered by Emby Server and lists them on its settings page. Each renderer can then be enabled or hidden individually.

A hidden renderer is filtered only from Emby's DLNA PlayTo discovery path. The plugin does not change the device itself, does not add firewall rules and does not patch Emby.Dlna.dll.

New renderers are visible by default.

Important limitation

This plugin filters DLNA/UPnP renderers only. Chromecast targets and active Emby client sessions are discovered through different paths and are therefore not listed or filtered by this plugin.

Compatibility / current testing

Current release: v0.1.4

Tested successfully with:

• Emby Server 4.9.5.0
• Synology DSM 7.2
• Denon AVR-X4400H
• Sony soundbar
• custom DLNA-to-HEOS bridge renderer

The plugin targets netstandard2.0.

Technical note

Emby's public device discovery API does not expose a per-renderer ignore hook. The plugin therefore uses reflection to replace only the DeviceDiscovered callback belonging to Emby.Dlna.PlayTo.PlayToManager with a proxy.

The implementation is deliberately fail-open: if a future Emby release changes that internal handler and the plugin cannot locate it, nothing is blocked and Emby continues normally.
