https://www.w3.org/Bugs/Public/show_bug.cgi?id=25269 --- Comment #7 from David Dorwin <ddorwin@google.com> --- (In reply to Joe Steele from comment #6) > The > information about how to use the key ID to decrypt content is contained > within the PSSH. If the PSSH is not present, in general the DRM does not > have enough information to retrieve the key needed to decrypt the content. Are you referring to information related to key chaining and/or domain keys? CENC specifies AES-CTR mode, so it's unclear what else is necessary to map a key ID to a decryption key and apply it. I wouldn't say that the key ID is not enough in general. There are plenty of services in production where it is. -- You are receiving this mail because: You are the QA Contact for the bug.
