Does GStreamer-Java works with Wayland?

[Davide Perini]

Hi all,
I am trying to capture the screen with GStreamer Java on Wayland because
Xorg is going to be deprecated everywhere...

It seems that Wayland uses a complete different way to capture the
screen and it seems that GStreamer needs pipewire to record the screen
on Wayland .

I'm not an expert and I'm struggling in understanding what is the right
way to do it with GStreamer Java.

I have found this python example:
https://gitlab.gnome.org/-/snippets/19

but I'm not able to transform it with something "compatible" with
GStreamer Java.

Do you think that GStreamer Java is currently able to record screen on
wayland?

Thanks
Davide

I saw your posts about this on the main GStreamer list.

If GStreamer can do this, GStreamer Java can do this. But, the
majority of that code seems to be setting up DBus messages to control
and acquire the pipewire source to pass into the GStreamer pipeline
description. That's not part of GStreamer or GStreamer Java
themselves. You might want to look at a Java DBus binding.

Best wishes,

Neil

Ok,
thank you Neil, I really appreciate the answer.

I'll try to figure out how to make it work.
If I will ever be able to do it, I'll create a GIST for poeple who may
be interested in it. :)

Have a good summer Neil and I hope good holidays too!

Kind regards
Davide

at the end, Wayland support has been added, GStreamer Java is a masterpiece :)
