The Fix: x86-64 Branch with CEFCodecFix
To Install, first select your Operating System:​
After Trying The Fix, Still Not Working
  1. Completely close GMod and restart it
  2. Make sure you're launching GMod through CEFCodecFix, otherwise Steam might overwrite the patched files
  3. Try Uninstalling VLC Media Player
    • If you have VLC version 2.2.2 or above, it may be causing an issue. Uninstall VLC Media Player and then Reinstall it, unchecking the "Web Plugins" option during setup.
If you find that you're having issues after having tried all of this and have already restarted GMod, reply to this thread and we'll try our best to help.
