Are you really sure?  

Fairly certain. Patches were added with support for GLK.

Look here for example:

https://patchwork.kernel.org/cover/11142231/  

Ok, can someone explain what that means in practice so far? The linked description states HDR support only on DP for Gemini Lake and on what platform and with what kind of Player? KODI I guess and Linux, but more specifically please? And can we expect it to work also with HDMI anytime soon?

just a short question to the Intel-Gemini-Lake community:
Is here somebody who is running Kodi under Ubuntu (or similiar OS)? Could you please have a short view on an other thread here:
frame-stuttering issue
Can you confirm this problems?
I know, HDR, Dolby Atmos, etc. are much more up-to-date, but smooth video-playback should be basic, shouldn't it...

And i know, that the J4005 is the lowest end of the gemini lake with UHD 600 and that J5005 is probably the better choice (2vs4 cores, UHD 600 vs 605).

Now the question: should 4k 60Hz with 10bit HDR run as well on the J4005?

Asking because in this test (https://www.elefacts.de/test-68-intel_nuc7cjyh_im_test_mit_libreelec_und_unter_windows_10) which is running on Kodi in Windows, the test file did run perfectly on the J5005, but not on the 4005, and the CPU Speed was not the problem (was at 20-30% usage).
Can anyone confirm that 4k 60Hz 10bit will make problems with J4005 on libreelec?

It's quite only the matter of the IGP, not the CPU power itself with video playback. UHD with HDR video playback sometimes needs a quite a bit of a IGP craft. See that even the Vega 8 and Vega 11 IGP's in the Ryzen APU's are just the very entry level for 4K / HDR and those are much powerful IGP's than any other Intel currently. Intel's may also could do to some kind of level, but it also depends on such things like how demanding is to playback the particular video: bitrate/codek/fps/HDR/ and the playback software that mostly matters. So in this state i guess, it's kind of very unpredictable to tell anything for sure how it would turn out (if anytime) in practice for Gemini IGP's. Needs than lots of testing, with lots of different test videos, many different playback software options and settings tweaking all around.

Obviously Codec is HEVC (H.265), which all this thread is about! And Bitrate: well what the Profile Main 5.1 has it's specifictions.
This aside the Questions were:
Should 4k 60Hz with 10bit HDR run on J4005  as well as it does on the J5005?
And: can anyone confirm that 4k 60Hz 10bit will make problems with J4005 on libreelec?

Ok, maybe we both missed a bit of the point of the others explanations. My answer still stand so and still somewhat relevant, but than I repeat the headline: I guess that in this state of development, it's all still be guessing and unsure prediction to state anything regarding.
