Question: different protection scheme per output/variant

[truong-hua]

We are using Shaka Packager 3.4.1 and it's working well. However, we are looking for a way to generate a single HLS manifest that contains both CBCS and CENC scheme for improving compatibility purpose because not all devices are supporting CBCS while Apple only support CBCS with fMP4.

Currently, --protection_scheme is a global option. So I have no idea of how to create a multiple scheme HLS/DASH. So that the player can select the best variant to their specifications.

HLS requires all variants to use the same encryption scheme, and Apple only supports CBCS with fMP4. To ensure compatibility, create separate manifests for CBCS (Apple) and CENC (others). DASH supports multiple schemes via AdaptationSets.
