Fixing intro video not playing in some Proton games (Media Foundation)

October 15, 2019 - Reading time: ~1 minute

I noticed Deep Rock Galactic had no intro video under Proton. I fixed it by installation the Media Foundation fix from GitHub https://github.com/z0z0z/mf-install.

WINEPREFIX="/home/omano/.local/share/Steam/steamapps/compatdata/548430/pfx" ./install-mf.sh

Another version of this fix that can work for other games https://github.com/z0z0z/mf-installcab.
