# The official VLC package will make OBS crash when a VLC source is used.
# The issue is that VLC and OBS are compiled with different lua version.
# So I also created vlc-luajit, a VLC package compiled with the same lua as OBS.
# But to make people unable to install VLC official package with obs-studio-tytan652.
# I decided to make vlc-luajit a dependency of OBS rather than an optional one.
