thanks.

But this is still image, no? Does it work in cingg? ;)

I wonder about  *video* HDR file, it usually in mp4/mov/mkv or even mpegts
container (UHD blu-rays, commercially done).

I used iphone11 file from Kodi samples wiki, but as turned out Apple *is*
special even in this area .....

And by the way only High Sierra and up can deal with HEVC (h265) video
natively, so no easy check for my FCP-on-Sierra Hack  :(

mplayer plays it washed out (and very slowly anyway), VLC 3.0.11 just show
freeze frame.
