Shaka Player is an open-source JavaScript library for adaptive media. It plays
adaptive media formats (such as DASH and HLS) in a browser,
without using plugins or Flash. Instead, Shaka Player uses the open web
standards MediaSource Extensions and Encrypted Media Extensions.
Shaka Player also supports offline storage and playback of media using
IndexedDB. Content can be stored on any browser. Storage of licenses
depends on browser support.
Our main goal is to make it as easy as possible to stream adaptive bitrate
video and audio using modern browser technologies. We try to keep the library
light, simple, and free from third-party dependencies. Everything you need to
build and deploy is in the sources.
For details on what's coming next, see our development roadmap.

NOTES:
- ²: The latest stable Chromecast firmware is tested. Both sender and receiver
can be implemented with Shaka Player.
- ³: Tizen 2017 model is actively tested and supported by the Shaka Player
team. Tizen 2016 model is community-supported and untested by us.
- ⁵: These are expected to work, but are not actively tested by the Shaka
Player team.
- ⁶: These are expected to work, but are community-supported and untested by
us.
- ⁷: These are expected to work, but are community-supported and untested by
us.
NOTES for iOS and iPadOS:
- We support iOS 9+ through Apple's native HLS player. We provide the same
top-level API, but we just set the video's
src element to the manifest/media.
So we are dependent on the browser supporting the manifests.
- Since iPadOS 13 MediaSource Extensions is supported
- Since iPadOS 17 and iOS 17.1 ManagedMediaSource Extensions is supported
Manifest format support matrix
| Format | Video On-Demand | Live | Event | In-Progress Recording |
|---|
| DASH | Y | Y | - | Y |
| HLS | Y | Y | Y | - |
You can also create a manifest parser plugin to support custom manifest
formats.
DASH features
DASH features supported:
- VOD, Live, and In-Progress Recordings (dynamic VOD content)
- MPD@timeShiftBufferDepth for seeking backward in Live streams
- Multi-period content (static and dynamic)
- Xlink elements (actuate=onLoad only, resolve-to-zero, fallback content)
- All forms of segment index info: SegmentBase@indexRange, SegmentTimeline,
SegmentTemplate@duration, SegmentTemplate@index, SegmentList
- Multi-codec/multi-container manifests (we will negotiate support with the
browser and choose the best ones)
- Encrypted content (including custom ContentProtection schemas, PSSH in the
manifest)
- Key rotation
- Trick mode tracks
- WebVTT and TTML
- CEA-608/708 captions
- Multi-codec variants (on platforms with changeType support)
- MPD chaining
