hevc_hardware_encode

This capability returns a HEVC standard level that indicates hardware-accelerated encode support by the device’s chipset at a particular standard level’s resolution and framerate. More information about the H265/HEVC standard levels are available here. [http://www.itu.int/rec/T-REC-H.265-201612-I/en] (tables A.9 and A.10). If hardware-accelerated HEVC encode is not supported on the device, it will return “-1”.
