Abstract
In one example, a device for processing decoded video data a video decoder implemented by one or more hardware-based processing units comprising digital logic circuitry, and a postprocessing unit implemented by one or more hardware-based processing units comprising digital logic circuitry. The video decoder is configured to decode video data of a video bitsream according to a video coding standard, extract HDR postprocessing data from an SEI message of the video bitstream, and provide the decoded video data and the HDR postprocessing data to the postprocessing unit. The postprocessing unit is configured to process the decoded video data using the HDR postprocessing data according to the video coding standard. The device may additionally determine whether the video decoder is compliant with the video coding standard by comparing the processed video data with reference processed video data.
