Technologies for adaptive real-time media streaming include a computing device to determine, by a trusted execution environment of the computing device, a current workload of the computing device based on at least one activity counter. The at least one activity counter is to record counter data associated with performance of the computing device. Further, the computing device determines a residual workload capable of being supported by the computing device based on the determined current workload and a new content playback characteristics for streaming media content based on the determined residual workload. The computing device streams media content received from a trusted server based on the determined new content playback characteristics.
