Hello everyone
For a long time i'm trying to solve a problem on playback Film or TV shows that occurs randomly but quite frequently during the film.
It is so random that it can occur at different times and frequencies on multiple plays of the same film.
DESCRIPTION:
As i said bebore during playback of video in 4k HDR 10bit (with bandwidth around 60-75Mb/s only for video) occurs randomly a sort of "long lag" where the audio continue to play flowlesly and without interruption, the video start move on frame by frame. This obviusly cause a desync of audio and video, in a manner that seems the video trying to catch the audio. Sometimes on screen appear the loading cirlce.
The only way to retrive this behaviour is pause playback (and the audio stop immediately) while the vidieo continue to move on frame by frame until after an amount of time the video stops to move frame by frame and the playback is (really) in pause. Or alternatively (the fastest way) exit the playback and restart it.
If I manage to record the event I will post a video of what is described. I apologize but this behavior is quite difficult to explain.
MY SETUP:
CPU: Ryzen 3 3200G
GPU: the processor iGPU (vega 8)
RAM: HyperX FURY 8 GB (1x8 GB) DDR4 2666 MHz
MOBO: Gygabyte B450M DS3H
In addition:
WHAT I TRIED:
In a frist attempt i thought was a buffer problem so following this docs I had increease cache/buffer with this:
I monitored the GPU usage during playback but nothing strange detected, usage stay around 70% usage. Temperature of CPU an GPU around 30°C with spikes of 40°C
I can try to enable selective debugging on kodi but idk waht component enable maybe ffmpeg?
I hope to solve this problem because it's strange and i don't understant how is possible that a powerful CPU like ryzen that have vega8 iGPU have trobule on 4k HDR when a fire TV stick or google cast can handle it with no problems.

In addition:
- The playback is handled by the build above with jellifin add-on configured in add-on mode.
- Another server with jellyfin take care of media library and streaming.
- The connection between server and HTPC is rocksolid 1Gigabit.
- The HTPC is connected to an AV reciver trought HDMI for audio and video playback.
- Audio on kodi is configured to passtrough to the AV receiver.

Nothing changed, maybe need to increase it futher? idkadvancedsettings.xml:
<advancedsettings>
<cache>
<memorysize>139460608</memorysize>
<readfactor>20</readfactor>
</cache>
</advancedsettings>
