           Summary: MEDIA_ERR_ENCRYPTED should exclude decrypt failure
           Product: HTML WG
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Encrypted Media Extensions
        AssignedTo: adrianba@microsoft.com
        ReportedBy: fischman@google.com

defines MEDIA_ERR_ENCRYPTED to encompass various problems including: "The
provided key could not be successfully applied".
This condition is impossible to implement in some encryption schemes and
difficult to implement in others.  It implies authentication (to differentiate
between a decryption error and a decode error where decryption "succeeded" but
generated garbage plaintext b/c of corrupt/incorrect key material or
ciphertext) and is thus misleading, so it should be dropped (and a decode error
event fired, instead).
