crash on start with "JS ERROR: Error: Failed to create gtk4paintablesink"

[violoncelloCH]

Hi, Thanks for the promising looking app! I tried installing it on Fedora 40 following the instructions (as a Flatpak). However when starting the app, it doesn't launch. When starting from the terminal, I get the following error output:

$ flatpak run com.vixalien.muzika.Devel 
Gjs-Console-Message: 10:21:28.041: caching soup requests at /home/jonas/.var/app/com.vixalien.muzika.Devel/cache/com.vixalien.muzika.Devel/soup-cache

Am I missing something?

having this issue as well. perhaps related to this? https://discourse.gnome.org/t/creating-gstreamer-sink-for-widget-in-gtk4-application/13220/5

gtk4paintablesink is not included in the Flatpak SDK yet, see Ship gst-plugins-rs together with the other GStreamer components (#1502) · Issues · freedesktop-sdk / freedesktop-sdk · GitLab 35.

You would have to build it as part of your Flatpak application.

i am not familiar with gtk4 development but the implication of the above comment seems to be that you yourself need to ensure the right gst plugins are included in the flatpak

[vixalien]

you yourself need to ensure the right gst plugins are included in the flatpak

Yes indeed, we are building the gst-plugins-rs ourselves in the flatpak (see https://github.com/vixalien/muzika/blob/main/build-aux/flatpak/modules/gst-plugin-gtk4.json) however a recent update or something caused it not to be packaged correctly...
