Several approaches have been proposed to address the challenge of decrypting MPD files. These approaches include:
<MPD> <Period> <AdaptationSet mimeType="video/mp4"> <ContentProtection schemeIdUri="urn:uuid:edef8ba9-79d6-4ace-a3c8-27dcd51d21ed"> <cenc:default_KID>12345678-1234-1234-1234-123456789abc</cenc:default_KID> </ContentProtection> <SegmentTemplate media="video/$Number$.m4s" init="video/init.mp4"/> </AdaptationSet> </Period> </MPD> decrypt mpd file exclusive
