Quote from DaCHack

- is it possible to use the addon on any system with gstreamer installed (eg osmc)

Sorry for delay getting back to you DaCHack.

~~The add-on is wrapped up inside a docker container, so wouldn't have access to OSMC's gstreamer library files.~~

~~I guess an add-on could be made to use a binary executable of the UxPlay rather.~~

I might be a bit out of depth answering your other questions. I haven't kept up with UxPlay's developments.

Potentially X11 is optional. I doubt it accesses the framebuffer.

As far as I recall when closing the connection the UxPlay instance disappears off the screen.

Okay I've managed to update add-on to only build UxPlay using Docker.

It'll then fetch the necessary GStreamer plugins and extract them into add-on lib directory.

Release 0.0.4 · markst/plugin.audio.uxplay

github.com

I'm sure some further improvements can be made & the dependencies could all be replaced.

The add-on works for me, but need to investigate the performance & whether it's using hardware-accelerated videosink plugin.

Thanks Cfan. Managed to get it working using the compiled binary (rather than docker container).

Only I'd rather whittle down the number of GStreamer plugins I've added to get it working.

Ah I've just found this post: Integrate AirPlay mirroring with RPiPlay

Which I is pretty relevant given UxPlay is a fork of RPiPlay.

However I'm using LibreELEC-RR fork which does include gstreamer

Thread

LibreELEC-RR [ Brave | Spotify | Moonlight | Emulationstation | Retroarch | Pegasus ]

LibreELEC-RR 10.0 / master-rr

Abstract

This fork comes with all stock LibreELEC features but also with 3 different emulation frontends which were integrated into the Kodi Estuary theme. They allow you to run several libretro & standalone emulation cores to play basically all games of the common home consoles, arcade & home computer systems of the last decades. Moonlight allows you to stream your favorite games from your gaming pc if you use a Nvidia Geforce GPU & Generic builds feature Brave…

Haven't been able to get missing GStreamer plugins working when using binary rather than docker container.

Wonder what the licensing implications are for including binary & dependencies in an add-on?

Okay managed to add binary dependencies to add-on /lib directory.

But will need to figure out including GStreamer missing plug-in:

Code

raop_rtp_mirror video ntp = 1643282602201152, now = 1643282602113116, latency = -88036

GStreamer error: Your GStreamer installation is missing a plug-in.

I wonder if it might be possible to create a binary with statically linked libraries included in the addon rather than building & running in a docker container?

uxplay: error while loading shared libraries: libplist.so.3: cannot open shared object file: No such file or directory

I did need to add the following to my autostart.sh:

Code

pactl load-module module-udev-detect
pactl set-default-sink alsa_output.pci-0000_04_00.1.hdmi-stereo-extra3

Harvie's mention of integrating UxPlay into Kodi let me to investigate whether it might be possible to use a Docker container. https://github.com/xbmc/xbmc/issues/20838

I've put something together quickly which works:
