... in which case the problem is that inline/thumbnail usages of videos by default use a 'popup transform' that -- until currently desktop-only JavaScript is loaded -- is just a thumbnail image plus a link to the original file. (The code for the proper player is hidden away where it can be loaded into a popup window by the JS.) This is pretty awful on mobile at present, as the thumbnail does nothing when you click on it, while there's a 'play media' link that sends you to the highest-resolution file you could possibly download. This means you're trying to play a full HD 1920x1080 video from the original VP9 source, which while a great format can be somewhat CPU-intensive. I have some planned refactoring that should improve this by including a stripped-down player inline for the mobile/non-JS cases, but beware it wouldn't get deployed until sometime mid to late next week even if we hurry it.
