Video player requirements
VoV video player needs to satisfy these requirements:
- RTMP support
- Fallback to HTML5 video when Flash player is not supported (iOS)
- Javascript API that works identical in Flash mode and HTML5 mode
Features that are nice to have but we can write them ourselves
- Playlist
- Clip making
- Closed captions
- Blocking access to certain segments of a video
Features that are nice to have but will be difficult for us to implement
- Plugin support
- Skinnable
- Adjustable playback speed (US 56)
- Adaptive bitrate
Features that we will most likely want to write ourselves
- Annotations using OAC
