OpenCDM/CDMi (Multi DRM) work with WPE & Chromium
summary
Linaro OpenCDM/CDMi adds WPE browser support to the existing Chromium integration and routes EME calls via a unified RPC layer; validation shows ClearKey and PlayReady validated playback on an RDK Morty OE image with the Westeros Wayland compositor, but Widevine remains in progress. Decryption runs inside OP-TEE on HiKey (only decryption is in the secure world; full secure media path is not yet implemented). Changes include 32-bit OP-TEE fixes and a pending upstream pull request; Chromium regression tests pass.
