Arch Linux User Repository

Presets are installed in /usr/share/obs/obs-plugins/input-overlay/presets.

I've updated the source that was failing.

I cannot install the package, could you help me with that error?

Thanks. I guess that PKGBUILD assumes an unmodified BUILDDIR in makepkg.conf but I was able to make do. The older version works, but if I restart obs after adding the source it seg faults again. Tested on a clean ~/.config/obs-studio.

EDIT: obs-plugin-input-overlay-bin works so I'll just use that for now

Sorry, I can't get keyboard or mouse overlay to work on wayland or xwayland. I fixed the undefined symbol problem but it still won't work. You can try an older version with this pkgbuild: https://pastebin.com/v60iCgkn

If OBS crash, try restarting it in safe mode, delete input overlay sources, restart obs in normal mode and recreate them.

I haven't tried the plugin for a while but when I load it up now I can see the overlay image but it's not able to read any of my keyboard/mouse inputs.

I see this in the log:

info: [input-overlay] No joysticks/gamepads found
warning: load_backend [542]: Failed to open backend 'x11': /usr/lib/obs-plugins/input-overlay/libuiohook-x11.so: undefined symbol: libinput_event_get_type!
error: [input-overlay] An unknown hook error occurred. (0X10)

Anyone else seeing this?

I bumped the version of the plugin to the latest commit as well as for libuiohook with some fixes. I hope it's not too buggy.

just checking in to confirm that my issue as well completely disappears if i use an alternate makepkg.conf (makepkg --config /etc/makepkg.conf.obs-plugin-input-overlay), in which the only change from /etc/makepkg.conf is changing march=x86_64 to march=native. my (normal) makepkg.conf is mostly stock otherwise, with the only differences being:

1. i use: OPTIONS=(!strip docs libtool staticlibs emptydirs !zipman purge !debug !lto) instead of the default: OPTIONS=(!strip docs libtool staticlibs emptydirs !zipman !purge !debug !lto !autodeps)

2. i use -j16

Changing march from x86-64 to native does indeed fix the compilation issue.

I was able to reproduce it using default flags. Can you try to change march to native? It looks like an upstream problem on OBS. SIMDe recommend to define SIMDE_ENABLE_NATIVE_ALIASES only for testing.
