With a key file in place, the associated CMAF MPEG-DASH stream is encrypted using CENC-PlayReady or CENC-Widevine encryption before being delivered.

How do I play a .MPD file?

You have to enter the URL of your MPEG-DASH stream (mpd file) and click on the big, yellow button for the player to play it back. THEOPlayer's demo player provides a bunch of useful information next to the video itself that is useful in keep track of the playback and debugging issues if they arise.

If you have the key used for encrypting the content, You can try the dashdownloader script from github hosted in Drm-Dash-stream-downloader repository. It uses ffmpeg for aes-128 encrypted content and mp4decrypt from Bento tools SDK for other cipher suites.
