Welp I got curious whether I'd missed a step so I gave it a once over, took me 7 hours to get it working. Turns out Proton does not like to run from an NTFS partition so I reinstalled steam on ext4. Now it runs but I couldn't get Direct Show to work, only the VLC video-path. I assume the LAV installer failed somehow. I also had to mount bind my external drive in my home folder otherwise it wouldn't see it. And I also had to reset whirligig's settings manually in the prefix folder (steamapps/compatdata/451650/pfx/drive_c/users/steamuser/Application Data/Whirligig/production) because it randomly stops accepting inputs. Just writing it all out in case somehow comes across it.

Oh yeah, that's a fair point, I have encountered the input lock issue before. Hopefully it will be fixed in future.

VLC also works for me from the start, but seems to lag at higher resolutions, hence fiddling to get DirectShow working.
