I am trying to play content using a DASH manifest with Widevine DRM based on the guidelines provided by the Roku developer forum, but it's not functioning correctly - I get a Protected content license error. with
buffer:loop:/build/work/7bee3a1850ffbe4e/os/RokuOS/System/Source/DRM/DrmEngine.cpp:DRM exception: No addon found for widevine:extra:etype:buffer as an error string
I initialized the native player according to the Roku manual, but it keeps throwing this error on protected content. What can I do to fix this?
