Such as: - video_xblock.py with Python side of the VideoXBlock - backends directory with BaseVideoPlayer class and it’s minimal implementation DummyPlayer - student_view.html a template to render video - Documentation in README.md - setup.py with module specifications - bower.json with external JavaScript dependencies - requirements.txt with Python dependencies

Brightcove video players are special. They are based on a Video.js but are loaded from the player.brightcove.net. Hence we use separate css. - backends/brightcove.py is a server-side part responsible for the logic - static/html/brightcove.html is a template to render video player. Also includes styles for Brightcove’s ‘default’ theme - static/css/brightcove.css is a video.js skin definition to replicate Open edX video player look
To turn on playback rates support for all video.js plugins we patch video.js Tech component.
Playback state includes: - Current time to within 1 second. Unique for each player - Playback rate. Unique for user, shared between players - Volume. Unique for user, shared between players - Muted. Unique for user, shared between players Playback state is loaded after Video.js player is fully initialized and passed from server in the video player’s template at rendering time. Every video player is rendered inside an iframe and doesn’t have access to xblock’s runtime. So they post their state to a parent frame as a message using `Window.postMessage`. Parent frame in turn accepts and verifies the state and post it to the server to a json handler resolved by `runtime.handlerUrl(element, 'save_player_state’)` method. Playback state is being saved at following events: - Volume change - Playback rate change - Play - Pause - Video ended
