Video player requirements

Meeting Scheduled!

There will be a meeting at 11:00 EDT on 30 March 2012 to discuss player requirements with interested projects.

Adobe Connect meeting location: (enter meeting as a guest, providing your name and affiliation)

Audio bridge option:

  • Phone Number: (812) 856-3600
  • PIN:  001824#

Note: User story references (e.g., us18) refer to our user stories document.

VoV video player needs to satisfy these requirements:

  • RTMP support (us18)
  • Fallback to HTML5 video when Flash player is not supported (iOS) (us18)
  • Javascript API that works identically in Flash mode and HTML5 mode
  • Fullscreen capability (us61)

Features that are required and nice to have built-in but we can write them ourselves

  • Playlists (us11) - list of videos or clips that can be played back in sequence, shared with others, can be manipulated through JS.
  • Clip making (us3, us64) - portions of videos can be defined, played back, and shared with others
  • Closed captions (us43) - ability to toggle on/off
  • Accessibility (us10) - section 508 (support for use by people with disabilities)
  • Blocking access to certain segments of a video (us90) - parts of a video can be restricted based on role, to support IP, ethical, or religious concerns

Features that are not required but would be nice to have and difficult for us to implement

  • Plugin support - possible to write plugins to add functionalities to both Flash & html5 players
  • Skinnable, configurable layout - for look & feel, branding...
  • Adjustable playback speed (us56 - is this possible with streaming?)
  • Adaptive streaming - the player can change video quality (when switching to fullscreen or connection slows down)

Features that we will most likely want to write ourselves

  • Annotations using OAC (us23, us26, us27...) - end-user annotations can be created and shared according to authorization rules; may need both adjacent and overlaid display of annotations
  • Embedding (us55) - player and a flexible subset of components can be embedded in a web page, CMS/LMS page

Other requirements

  • MIT/BSD/ECL compatible licensing (not GPL)
