All three components have Requires: gupnp-1.2 >= 1.2.0, glib-2.0 >= 2.28 in the pkg-config files. So they should be still propagated.

Wait why would this need to propagate? previously, -core propagated because it was needed for renderer/server. However, now that it is all combined and built all at once, i don't see the need for the propagation anymore

All dependencies transitively listed in Requires field of a .pc file need to be on PKG_CONFIG_PATH or for the dependency defined by that .pc file to be found.

We typically add them to propagatedBuildInputs so that we do not need to add those transitive dependencies to buildInputs each dependent of the .pc file.

Though it looks like there are no dependents for the dleyna .pc files so perhaps the point is moot:

https://codesearch.debian.net/search?q=dleyna-renderer-service-1.0&literal=1
https://codesearch.debian.net/search?q=dleyna-server-service-1.0&literal=1

Currently there is not even a .pc file being installed - is that a problem?

I tried testing it but so far I did not even manage to make it work in other applications.

• I set up minidlnad (with videos, audio and pictures) on my router and verified that it works on VLC on Android.
• Opened firewall ports on my desktop, not sure if necessary or complete: sudo nixos-firewall-tool open tcp 2869 and sudo nixos-firewall-tool open udp 1900
• In VLC on Desktop, open View » Playlist, check that the server is listed in Universal Plug'n'Play: The tab is empty
• ${gupnp-tools}/bin/gssdp-discover --interface=wlp3s0 does not show any available messages.
• Kill running dleyna processes if present, run ${dleyna}/libexec/dleyna-renderer-service to let the new version bind to D-Bus address.
• Add grilo-plugins to buildInputs of rhythmbox, enable "Grilo media browser" plug-in: Nothing listed
• In GNOME Music, nothing listed.
• In GNOME Photos nothing is listed.
• In Totem, I get ton of grl_source_resolve: assertion 'GRL_IS_SOURCE (source)' failed criticals but same on master.
• ${gssdp-tools}/bin/gssdp-device-sniffer --interface=wlp3s0 does not show anything.

Uh oh - I was happy to see it listed in journal, but seems i have some work to do!

I just wanted to check that it still works (I last tested it ages ago) but did not even get it to work on nixos-unstable. The whole DLNA/UPNP ecosystem has always been extremely flaky in my experience (slow ARM devices taking tens of seconds for every request, often timing out or otherwise failing because the implementation is broken).

I just gotten VLC on my desktop PC to discover the DLNA server and play the files once but after restarting VLC, I cannot get it to work again.

So I would probably not spend too much time on it. Especially when of the four apps (Totem, GNOME Photos, GNOME Music currently filtered out, Rhythmbox), only the last one is somewhat maintained and the package does not even include the necessary grilo-plugins.

Edit: There is also pragha but there, the grilo-plugins are disabled by default.
