 > developers quickly loose interest...
 No! Nobody looses it!
 I just posted
 thishttps://patchwork.ffmpeg.org/project/ffmpeg/patch/20200223234124.17689-18-sw@jkqxz.net/
 that transfers this external metadata in internal metadata! But even after
 that we will still need to support HDR10 static metadata BT.2390 DTM in
 sidedata with Pludge constant and Hermite curve to present HDR10
 correctly! OMG, we are doing it! Everythimg is already here, Madvr support
 DTM, dolby vision polinomials are also here, HDR10+ will be soon given by
 google, dammit, THERE IS A SCRIPT TO COPY METADATA. NVENC and NVDEC both
 support Dolby Vision (in NVAPI) and HDR10+ (rigaya).
