Abstract: A compute device implements a technique for facilitating selective access to hardware codec resources. The compute device executes, in a trusted execution environment, firmware for controlling graphics hardware of a device that supports a plurality of video codecs. The compute device obtains codec control data specific to the device from a remote system and then configures the firmware to implement a codec policy for selectively providing access to the plurality of video codecs based on the codec control data.
