I'm afraid the .ogv wont show video so please convert the ogv to an mp4.

What the... Welp, I guess I got ninja'd when I posted MC-131075, because this report didn't exist when I was originally writing mine, haha (the time stamps disagree, but I'm generally fairly thorough when trying to find already-existing reports, so I really don't know what happened here... maybe I fell asleep and finished writing it later or something). Feel free to check out my report if anyone wants to see more info on this bug.
