Description

Videos on Commons etc fail to play in Safari since this week's ogv.js update, which includes WebAssembly (.wasm) version of the codec modules.

The wasm payload fails with:

Failed to load resource: the server responded with a status of 400 (HTTP/2.0 400)

Example URL: https://commons.wikimedia.org/w/extensions/TimedMediaHandler/MwEmbedModules/EmbedPlayer/binPlayers/ogv.js/ogv-demuxer-webm-wasm.wasm?version=1.5.0-20171109103951-47c6ee5c

returns the text "Invalid file type"

Presumably this is a config issue on web servers.

Ok, this is fixed for now with the swap back to .js version
