Following my work on the AV1 encryption I refreshed the encryption element text/formatting, added some extra text. Some new pull requests in case anyone has issues with the added texts: - ContentEncryption was supposed to be absent in some cases but we can't require that. We can require <https://github.com/Matroska-Org/matroska-specification/pull/279>that it's ignored https://github.com/Matroska-Org/matroska-specification/pull/279 - the frame encryption wasn't clear what part of a Block it would encrypt/compress. It should be each frame, excluding the lacing parts https://github.com/Matroska-Org/matroska-specification/pull/280 - make ContentEncAlgo mandatory, it has a default value of no encryption anyway https://github.com/Matroska-Org/matroska-specification/pull/281 I also added the 2 elements found in WebM that were not in Matroska: https://github.com/Matroska-Org/matroska-specification/pull/282 Too bad AESSettingsCipherMode doesn't have a default value, otherwise picking the AES encryption would automatically pick the only mode currently allowed in WebM.
