I humbly request that we allow video embeds in formats other than OGV. The Theora coding it uses produces relatively large files that often run afoul of the ~4 MB file size limit on Phabricator (or alternatively, extremely ugly files).
Could we allow embedding for some other file type as well, e.g. WEBM? WEBM file format is also free and widely supported by browsers, like OGV, and it uses much better coding (VP8/VP9).
For your reference, here's a bunch of tiny videos in different formats. Only the OGV video is embedded, the others are shown as links.
