Hello

I was looking at the DRM section https://google.github.io/shaka-packager/html/tutorials/drm.html

And I do not see how to use common encryption keys for MPEG DASH with WV and PR

such as providing only

Key

Key ID

PSSH

PR LA URL

Is there an example of this?

Thank you

Hi David,

If you have the PSSHs, you can follow the examples in https://google.github.io/shaka-packager/html/tutorials/raw_key.html. You can concatenate the Widevine PSSH and Playready PSSH in --pssh.

Let us know if it works for you.

If you have any suggestions on how we can make the documentation better and clearer, let us know too.

It is exactly the same as WV, with additional PR PSSH concatenated and provided via --pssh, i.e.

--enable_raw_key_encryption \

--keys label=:key_id={key_id}:key={key} \
--pssh {WidevinePSSH+PlayreadyPSSH}

This is a feature added recently. You can provide your own PSSH(s) if you have them or have Shaka Packager to generate the PSSH(s) for you by specifying the protection_systems that you want the PSSH to be generated.

Note that if your license server requires additional server specific information, then you'll have to use the PSSH from your server or DRM provider.

Your example of

Example with multi-drm (Widevine and PlayReady) lists no PSSH, do we not need to list it?
