Known issues with Media Encryption
There are some known issues that currently limit the use of Media Encryption (ME) in some scenarios.
|HLS byte-range playlists cannot be used with Media Encryption||
When Media Encryption is enabled for an HLS stream with byte-range MPEG-TS segments, incorrect byte ranges can be reported in the playlist file. So, when a player transitions from one bit rate to another, it can fail to append the new segment to the previous one in its playback buffer.
Some symptoms of this issue include the following:
|Existing stream-level encryption not supported||If content served by your AMD property is already encrypted using stream-level encryption (such as data encrypted via a DRM system implemented in your Media Origin), it is denied for processing, because it is already encrypted. In addition, the pass-through of pre-encrypted content is not supported. Attempts to do so are met with an error when the content is recognized as encrypted.|
