Shaka Player is an open-source JavaScript library for adaptive media. It plays
adaptive media formats (such as DASH, HLS and MSS) 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.
ā·: 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.
Other DRM systems should work out of the box if they are interoperable and
compliant to the EME spec.
NOTES:
¹: Only official Chrome builds contain the Widevine CDM. Chromium built from
source does not support DRM.
²: DRM must be enabled by the user. The first time a Firefox user visits a
site with encrypted media, the user will be prompted to enable DRM.
³: PlayReady in Edge does not seem to work on a VM or over Remote Desktop.
ā¶: ClearKey is a useful tool for debugging, and does not provide actual
content security.
ā·: These are expected to work, but are community-supported and untested by
us.

NOTES:

Safari. We do support FairPlay through MSE/EME, however. See the
streaming.useNativeHlsForFairPlay configuration value.

Content Steering features supported:
TTL, if missing, the default value is 300 seconds.
RELOAD-URI, if missing we use the url provided in the manifest as fallback.
PATHWAY-PRIORITY only HOST replacement
Content Steering features not supported:
PATHWAY-CLONES other replacements than HOST.
VR support
Shaka Player supports VR when:
Content is automatically treated as VR if it fits the following criteria:
HLS or DASH manifest
fMP4 segments
Init segment contains prji and hfov boxes
Or, if it is manually enabled via the UI config.
VR modes supported:
Equirectangular projection with 360 degrees of horizontal field of view.
Half equirectangular projection with 180 degrees of horizontal field of view.
Cubemap projection with 360 degrees of horizontal field of view.
NOTES:
VR is only supported for clear streams or HLS-AES stream. DRM prevents
access to the video pixels for transformation.
