Popcorn.js is Mozilla's JavaScript library for building timeline-based interactive media experiences in the browser. It normalizes HTML5 audio/video APIs (plus YouTube, Vimeo, SoundCloud) and lets developers trigger web content and events at specific times in a playback timeline via a plugin architecture.
Use cases
- synchronize web page content with html5 video playback
- create interactive timeline-based video presentations
- show maps, captions, or wikipedia entries at specific moments in a video
- add timed overlays and events to youtube or vimeo embeds
- build media-rich web documentaries or web productions
When to choose
- maintaining or extending an existing codebase already built on Popcorn.js
- you specifically need its timeline/plugin model and accept the unmaintained status
When to avoid
- starting any new project, since Mozilla no longer maintains it (last release 2017)
- you need modern browser support, security fixes, or bug fixes
- you need actual video encoding or processing rather than playback orchestration
