This demo shows off the WMP-SVG player, set to overlay controls when playing video only. It uses a playlist with three items:
Gameplay footage from Deus Ex: Mankind Divided (720p, 2:42, 51.5MB).
Gamplay audio from Halo 3: ODST (1:05, 1.51MB), to show off the player UI when controls aren't overlaid on video.
Gameplay footage from Halo: Reach (720p, 2:40, 98.9MB). This video has a (clumsily) handmade VTT file to show off subtitles. There isn't much we can do to visually configure subtitles (i.e. CSS can't move them out of the way of the overlaid video controls), but it's worth demonstrating that they at least exist.
