VLC doesn't load under Sway / pure Wayland

[ulysses4ever]

Describe the bug

When I try to open up VLC from command-line, it shows a number of errors and loads the CLI instead of graphical interface.

Steps To Reproduce

1. Load Sway with XWayland disabled
2. Open up a terminal
3. Run vlc.

Expected behavior

VLC loads the GUI, as it is the case with XWayland enabled or with any other window manager on XOrg.

Additional context

Here are the errors I see.

This doesn't seems to be a skins bug

BTW do you use xwayland?

Idk neither if it's enabled by default nor if vlc supports Wayland, so xwayland make it possible to use X applications on Wayland.

@lucasew I don't know if it's related to skins, I just tagged several recent committers to the VLC module as the the bug report template suggested. I'm sorry if it has nothing to do with your contributions.

I don't use XWayland, as it's noted in the original post. I think I used to be able to run VLC without it under Sway okay.

No problem

I was trying to isolate the problem, I am not sure if vlc has a good enough Wayland support so using xwayland should be the way.

The bruh moment is that I didn't seen the part where you said that you do not use xwayland, sorry about that xD

Indeed, after googling it harder, it seems that native Wayland (i.e. not XWayland) is planned for VLC 4:
