And I've attached the mediainfo. Funny thing is, as far as I can tell, the encode for this file is effectively the same as another one that I could play. I can provide the ffmpeg and the mediainfo on the other one if it's needed.

Nothing obvious to me. Whats the error you get?

It was something along the lines of the file was not supported. I went and tried it again to see if I can get the specific error message, but it plays the file fine now. I guess restarting the machines fixed it somehow? Anyway, sorry about that.
