Description
Many devices today ship with hardware-protected Digital Rights Management (DRM) pipelines built on GStreamer. Too often, developers assume that DRM is destined to remain proprietary and that the only way forward is with hacks and downstream workarounds. In practice, this leads to heavily diverging forks, making upgrades difficult, pinning products to ancient GStreamer versions, and exposing systems to severe security threats.
In this talk, Nicolas will walk through the emerging upstream architecture for hardware-protected DRM and Secure Video Path (SVP) on ARM devices using OP-TEE. Attendees will learn what is already in place upstream, what components are still in progress, the technical hurdles encountered along the way, and the strategies being used to solve them.
