Currently obs-studio does not start on Arch linux, it will fail with

obs: error while loading shared libraries: libbluray.so.3: cannot open shared object file: No such file or directory

streaming with NVENC H.264 works with workaround:

sudo ln -s /usr/lib/libbluray.so.4 /usr/lib/libbluray.so.3

current obs-studio and libbluray versions:

mdujava $ sudo pacman -Qi libbluray
