4K Playback issues on chrome Webapp

[Moreje 16]

Hi,

Here is my problem:

my emby server is running on Linux docker (latest beta), with NVIDIA GPU and Emby premiere (HW acceleration on)

since few days, I have bad issues when I try to watch 4K h265 movies on my PC (Google Chrome browser)

- screen goes black (indeed it is the whole Chrome app who turns black, on every windows. see capture

-Sometimes HW transcoding starts...sometimes it switches to software transcoding.

HW transcoding is working when reading h264 files

Any ideas to help me?

thank you

J.

EDIT after few tests:

I think I have multiple parameters problems

- the "black screen" issue seems to be related to Hardware acceleration in Google chrome advanced settings

-The HW transcoding issue seems to be related to Tone mapping! when activated, HW transcoding fails and switch to software transcoding. If this option is Off, HW transcoding starts...

Hi, the black screen is something you may have to play with google chrome hwa settings for, but @softworkz is looking into the transcoding error. Thanks.

Yes, the Nvidia tone mapping problem is a known issue. It will be fixed in the next beta (4.,7.0.18).
