4K HDR Video
Which OS/Application can play 4K HDR video?

Android 7.1?
Linux?  Which version?  Which player?

Ideally, I would like to play 4K HDR files with Python on Linux without a GUI.

Currently 4K HDR can only be played back on Android. But I've spoken to LibreELEC guys last week at FOSDEM and they are working on a HDR implementation. So I'd imagine it will be available on Linux in the near future.
You can find me on IRC, Discord and Twitter

The drivers for linux on RK3328 have been in the works for ~ a year, the RK3399 seems to have better linux support. Maybe the RockPro64 will be available first.
OK, I guess I should have researched it more.  I just assumed that since it is marketed as a "4K60P HDR Media Board Computer" that the OS support for it was already available.

Maybe I can do what I want to do in Android, instead of Linux.  Thanks
I’ve been able to playback 4k HDR videos via The Android TV image (Pine Installer) but I have been unsuccessful with the Rock64 outputting a HDR signal to my TV.

My TV prominently displays a HDR logo when a HDR video begins playing.

Any ideas how I should have this setup to no only playback HDR but also output the correct signal to my TV?

Than you

I prepared and tested HDR pipe MPP+DRM for Rock64 (HDR decoding and display 4k60 but display only 4k30 (eg. not HDR 4k60, but untested tested on new RockChip kernel patches)) - see MPP+DRM tests.
I found and resolved some faults in RockChip MPP and RockChip kernel 4.4. RockChip ignored any requests (see mpp#38 and kernel#61 ...) so I  stopped my development/troubleshooting of HDR pipe and any other RockChip code. MPV/Kodi are probably still blocked (kwiboo#22, kwiboo#24). RockChip marketing still say "4k60 4:4:4" (TMDS 594MHz) but limited in code (TMDS 371MHz, eg. 4k60 yuv420p10le) and true output has limits (TMDS 297MHz) on Rock64 with RockChip 4.4 linux  Sad .
I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" Angry. ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
