Out of curiosity, is there any reusable alternative for Google's Widevine module? It seems both Chromium and Firefox use this, and all other open source browsers are based on them. Safari and Internet Explorer DRM would be tied to specific platforms and also not reusable, I'm guessing?
How (re)usable is Adobe's Primetime DRM for something like this? Primetime was removed from Firefox in version 52 (pre-Quantum) in early 2017 [1]. Are there any others?
