With 4K Remux MPEG-H HEVC 2160p 10bit HDR10 / True HD/Atmos 7.1 24bit, it will pause/stutter on playback every few minutes and the only way I have found to smooth it out is turn subs off completely, switch to 5.1 dolby digital audio track then back to the True HD track then it seems to play for 30 minutes or so before happening again.
CPU/Mem/DIsk for media server at these points are hardly being touched so its not Disc I/O or CPU maxing out.
When I playback in browser with emby over HDMI to TV the colour is washed out. Same with Kodi.... so would be really like to get the LG app sorted.
I have the exact same problem and the reasons are now clear and the emby app is NOT responsible for the problem :-/
When I play a 4K Remux MPEG-H HEVC 2160p 10bit HDR10 / True HD/Atmos file (and True HD/Atmos is really the only format the playback is stuttering) I looked on the device manager of my Windows Server and determined that the HDD that emby uses to transcode is at 100% after a few minutes/seconds and that's exactly when the playback begins to stutter!
Even when I use a SSD to put my temporary transcoding path on, the problerm still exists... BUT the stuttering gets better... that's an indicator that the reason really is the speed of the HDD. because the system is writing to the harddsik with full speed and is trying the read from the same disc at the same time... I think if there woukd be a possibility to prioritize the read and write tasks of the system, that would solve the prob, but actually I found no way to do this.
True HD/Atmos is the only audio format that has to by transcoded by emby because the LG TV seems not to be able to play that naturally.
->When I playback in browser with emby over HDMI to TV the colour is washed out. Same with Kodi....
The reason for this is that your playback device you are running kodi on is not able to send the HDR information to your TV, maybe the graphics card is not HDMI 2.0 compatible or samething like that.
Kodi 17.x is not able to do a HDR to SDR conversion so that the colours are looking terrible and as you described "washed out".
The upcoming Kodi 18 is able to do a HDR to SDR conversion maybe you can try this one ;-) there is already a RC3 out and I think the final version will be there in a view days.
