I see this message too, but without any dropout. For LibreELEC I am using MSI Cubi N with a Pentium Silver N5000 (Gemini Lake) with 8GB RAM. I generally get this message when the 4k video file is already in cache in the NAS (my Unraid server on a gigabit LAN connection). If playing a file for the first time then the message is seldom seen. If I stop playback after a minute and then play the same file again from the beginning, the message will then pop up. It's almost as though the file data arrives too quickly. To me this suggests a possible arithmetic error in the source speed calculation caused by the data for the initial buffer fill operation taking very little time to arrive.
Interesting. I think some of the audio issues I’m having is that my HP T430 isn’t grounded properly, I hear a slight hum/pop in the background when nothing is playing, I also won’t get the Kodi UI sounds unless I continuously send audio to my receiver. But it doesn’t really effect watching movies all that much. I haven’t really played around with it enough.
Also, I fooled around with the acceleration settings in the Player menu on the Sep 4th build and once I turned off Vaapi I lost all the individual selections like AV1, etc. All I see now is the main Vaapi acceleration setting and none of the sub-selections.
Colorspace issue is a problem. Is there any way to get proper colorspace output? Coreelec will output Ycrcb properly on my Odroid N2, all this build outputs is RGB 36bit for everything.
Still impressed with my $45 HP T430. I opened it up last night, definitely embedded memory- wish I had noticed that fact before but for $45, the build quality and what it does it’s all good. Still way better than the million Chinese Android boxes that cost the same. Looks like it was EOL, it has an M2 wifi slot with no card.
