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"
},

"dash": ...],
"id": "",
"duration": 362,
"type": "Vod",
