v1.5.3

• Supported Serve API: v1.4.3 or newer

Added

• New utility load_xml() to parse XML data with lxml ignoring Namespaces.
• PSSH class now have __str__ and __repr__ methods to print the object in more Human-friendly ways.
  • str(pssh) is now identical to pssh.dumps().
  • repr(pssh) or just pssh in some cases will result in a nice overview of the PSSHs contents.
• New to_playready() method to convert Widevine PSSH Data to PlayReady PSSH Data. Please note that the
  Checksums for AES-CTR and COCKTAIL KIDs cannot be calculated as the Content Encryption Key would be needed.

Changed

• The System ID must now be explicitly specified when creating a new PSSH box in PSSH.new().
  • This allows you to now create PlayReady PSSH boxes.
• The playready_to_widevine() method has been renamed to just to_widevine().

Fixed

• Correct capitalization of the key_IDs field when making the new box in PSSH.new().
• Correct the value type of key_IDs value when creating a new box in PSSH.new().
• Ensure Key IDs are list of UUIDs instead of bytes in PSSH.new().
• Create v0 PSSH boxes by only setting the key_IDs field when the version is set to 1 in PSSH.new().
• Fix loading of PlayReadyHeaders (and PlayReadyObjects) as PSSH boxes. It would previously load it under the
  Widevine SystemID breaking all PlayReady-specific code after construction.
• Parse Key IDs within PlayReadyHeaders by using the new load_xml() utility to ignore namespaces so that xpath can
  correctly locate any and all KID tags.
• Support parsing PlayReadyObjects with more than one PlayReadyHeader (more than one record).
