Support for widevine multikey drm (key rotation)

Created by: biswarupdasgupta

Hi,

We are using videojs plugins play drm files. One of our client supports drm key rotation for widevine where different video tracks have different drm keys.

Example mpd file:

cenc:psshAAAALXBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAA0iBSAAJHEZSOPclZsG</cenc:pssh> 244c54d066d347659996215f3e23c420_896_v.mp4

and

cenc:psshAAAALXBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAA0iBSAAJHEZSOPclZsG</cenc:pssh> 244c54d066d347659996215f3e23c420_696_v.mp4

We wanted to check if videojs-contrib-eme or videojs-contrib-dash supports this feature and if yes how can we enable this.

Thanks in advance !
