Hi Carl,

It seems i have created a confusion here...By "ffmpeg supporting HDR
encoding" I meant wether ffmpeg can convert any random video to a 4K HDR
encoded content. I have already tested 4K and it works fine but its this
"HDR" piece thats troubling me and I havent even found a proper solid
source to understand HDR properly. on the top of that, how do we get to
know whether a content is HDR or SDR, is there any tool or a specifc
difference between them which can be reported by a tool?
