Explain your issue

Please check first if your issue haven't already been reported yet.

Videos are invisible on Linux, you can still hear the audio but no video will show. There is no console output or crash, you just can't see the video.

Here's a comparasion using a little mod with both game versions (Linux and Windows), same files and same script (pulled from the wiki):

import hxvlc.flixel.FlxVideo;
var video:FlxVideo = new FlxVideo();
video.onEndReached.add(function():Void
{
    video.dispose();

    FlxG.removeChild(video);
});
FlxG.addChildBelowMouse(video);

if (video.load(Paths.video("test")))
    new FlxTimer().start(0.001, (_) -> video.play());

Left game being the native Linux executable, and right being the Windows executable running under Proton (Experimental).

Have you tried following the instructions on the hxvlc library page that Codename uses? In my case, I'm on Fedora, so I had to install the vlc package that includes a few additional subpackages. On Fedora, that package contains the VLC media player itself, but also some extra things, such as the VLC library and vlc-devel, the latter being the respective headers necessary for compilation.

[NaviVani-dev]

Yep, I already installed vlc and libvlc before, the game actually crashes if you dont have VLC installed!!

I believe that it's the usual dynamic library issue with the crashing, though I've heard that it simply doesn't boot and doesn't explicitly crash during runtime, as that's generally how Linux's dynamic library loader should function.

In regards to the actual issue at hand, what would be your specs, such as your distribution (including variant, like with Fedora's spins or Ubuntu's editions) and your graphics card (and if you're using NVIDIA, what drivers? I don't have issues with the RPMFusion drivers on Fedora, though I'm on the Pascal series so it's somewhat stable)?

[NaviVani-dev]

I have an NVIDIA RTX 4060 Mobile (a laptop gpu eww), an intel Core i7 12th integrated graphics, a 1tb ssd and 32gb of ram, right now i have the nvidia-dkms drivers (575.64.05-2) and nvidia-utils (575.64.05-2) installed.

i recently tried to run the game on my integrated graphics to see if it was an nvidia problem but there is no difference

also, im using endeavouros (arch btw), hope this info helps a bit :>

[r6915ee]

I believe on Fedora, the drivers are based off of akmods (I don't know the differences, though).

Regardless, I have heard that later NVIDIA graphics cards have some weird issues, but I haven't really used a graphics card past Pascal before since my current machine uses a Pascal desktop graphics card, specifically the GeForce GTX 1060 6GB. I've really only heard from other people that most cards around Turing have some oddities. Even then, though, I wouldn't expect a lack of videos on the native build, since I don't have that issue.

I do know that videos are a key source of crashes (and I have faced off against that on a mod only a couple of days ago) but that's only if it points to a valid filepath, so I guess it's something with filenames knowing Linux since hxvlc can recover from wrong filenames, but I'm not sure.
