https://github.com/obsproject/obs-studio/issues/10852#issuecomment-2254511971
Updated the comment on that issue. OBS_PLUGINS_PATH=/lib/obs-plugins OBS_PLUGINS_DATA_PATH=/usr/share/obs/obs-plugins/ obs gets fade and cut to work - but segfaults on exit...
-.- well it looks like they dont care
can fix up with a patch for the dumb logic (plus add hardcoded system directories i guess, see 'second' below)
https://github.com/obsproject/obs-studio/blob/master/libobs/obs-nix.c#L92
struct stat stat_info;
for (int i = 0; i < module_patterns_size; i++) {
if ((stat(module_bin[i], &stat_info) == 0 && !!S_ISDIR(stat_info.st_mode) )
&& (stat(module_data[i], &stat_info) == 0 && !!S_ISDIR(stat_info.st_mode) ) )
obs_add_module_path(module_bin[i], module_data[i]);
}
first problem is bad plugins/dirs wipe old plugins. check if they exist
second problem they wont fix or say is a void issue for cmake vars
third is, shouldn't user supplied env vars override current plugins? basically the above fixed loop should go first, then the user provided stuff
add:
fwiw - this doesn't fix the double loaded plugins segfaulting on exit. it actually makes it more common because your plugins actually fukin load :)

@sgn thoughts?
Hardcodes plugin dir that's set at build instead of fixing cmake vars. Fixes loading duplicate plugin paths instead of on the deletion side.
This message is a bit misleading here: I do not have a .config/obs-studio/plugins. Also it's clobbered to extra / and %module%/data which can't really exist.

(updated patch aug 29 2024 - size check and warn)
Yup, OBS launches and records fine for me without the OBS_PLUGINS_PATH override (the segfault on exit stills happens when running with the override but it's a non-issue since OBS runs just fine without it) - perhaps this issue can be closed
