How to analyze an HDR video for peak brightness level for the setting of metadata?

I wanna do an encode of a HDR video I made. I'd like to include the global peak brightness metric in the metadata, and maybe the average brightness too. How can I find the brightest pixel in a HDR video (PQ curve) and then calculate the brightness in nits from its value? And how could I go about calculating the average brightness?
