Documentation

The Kaltura Player supports 360° video in both desktop and mobile device for any kind of motion: mouse, touch, device motion and keyboard keys.

This plugin is depended on three.js library.

The player will be informed that it deals with 360/VR media by populating attributes in the sources object which is part of the kaltura player config
it might be populted using providers or the app itself)

* metadata object must contain "tags": "360" and "vr": {} object which is not null.

in case app is using setMedia instead of load media tags and vr for 360 plyback these attribues are expected to be populated by app

#### Media Sources Example

`
{
"sources": {
"options": {},
"metadata": {
"tags": "360"
},
"hls": [...],
"dash": ...],
"id": "",
"duration": 362,
"type": "Vod",
"poster": "",
"dvr": false,
"vr": {},
"captions": []
}
}
`
