Using VLC sources in OBS will provoke "Segmentation fault" because VLC and OBS have not been built with the same Lua package.


Additional info:

I forgot to specify that luajit shall be installed as optional dependency for OBS to enable lua scripting

If you don't want OBS users to crash because of this incompatibility.

You can build VLC with luajit

OR

Disable VLC sources compilation from OBS with the `DISABLE_VLC` cmake flag

I assume we don't want to change the VLC dep? And if that's true I'll try the second option.

Disabling a default behavior due to upstream dependency, and upstream incompatibilities doesn't seem like the correct approach nor the Arch way. A wiki article to reference the incompatibility would suffice without altering the intended functions from upstream.

Not sure I agree here. @jayray, will you write the wiki entry? And how will it stop the crashing? Upstream report here [1] for reference.

@Toolybird you're right. After further thought it's not necessarily and upstream issue, it's a build issue. We shouldn't have to rely on AUR packages to build against a common LUA to get these to work as intended by upstream.
