Playing a beatmap with a video crashes on Wayland + AMD GPU

Crash to desktop

Bug description

Playing any map with a video causes a crash.

OS: Arch GNU/Linux
WM: Hyprland (Wayland)
GPU: AMD 6700XT
CPU: AMD 5800X

Thoughts: the crash says

Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
[AVHWDeviceContext @ 0x7ff338a945c0] VDPAU device creation on X11 display :1 failed.
corrupted size vs. prev_size
[1]    87298 IOT instruction (core dumped)  osu-lazer

but I have an AMD GPU, meaning that it's probably trying to open a non-existent Nvidia backend.

Version

2022.409.0-lazer

Can you confirm you actually have libva-vdpau-driver installed in the first place? That will eventually be shipped with the game rather than requiring linux users to install it (see ppy/osu-framework#4349).

Please post the output of ffmpeg -version.

It wasn't installed, after installing it, the issue is resolved. It should probably be added as a dependency in the AUR PKGBUILD.

Nvm, it crashed again. My FFMPEG version is n5.0

[frenzibyte]

Is it the same crash? please include the crash logs.

Downgrading to FFmpeg 4 should fix it for you. This is a dupe of ppy/osu-framework#4349.

[ThatOneCalculator]

Sadly looks like I can't downgrade.

[smoogipoo]

See #17345 (comment). This is going to be up to you to resolve for now.

Thank you! Editing line 7 of /usr/share/applications/osu-lazer.desktop to

Exec=env OSU_EXTERNAL_UPDATE_PROVIDER=1 LD_LIBRARY_PATH=/usr/lib/ffmpeg4.4:"$LD_LIBRARY_PATH" /usr/bin/osu-lazer

does the trick :)
