Adjust Display Refresh Rate and Resolution no whitelist match - nvshield - 2019-12-10
Hello everyone,
I am using Kodi for a while now and never had a problem with it but this time I am not even sure if it is a problem or not.
My Kodi is set to 1920x1080 for convenience (most stuff in 1080p) but everything is capable of 3840x2160, so I am using the resolution whitelist (every single one is enabled) for that.
Adjust refresh rate is set to on Start/Stop and everything worked like a charm no problem what so ever. They always changed according to the source material.
But now I´ve got a few files in 3840x2160 @ 23,98 normally that is no problem because it is in the whitelist or at least I thought so.
Playback is stuttering and far from the experience, I´m used to.
A little investigation later, I found my TV on 1920x1080 and not 3840x2160 and after reading about how to get a debug log and how to read it, (at least a little bit) this is what I found:

I´m sorry for not using the paste function but I thought this (log) is not to long. (If you want I can copy it over, just let me know
)As far as I can tell, Kodi is searching for the refresh rate of 47.952, which is the tbr of the (file) stream, but can´t find it because it is the double of the 23.98 fps shown in the stream and of course, it´s not in the whitelist.
So it sticks to the default resolution that Kodi is set to 1920x1080.
I found almost nothing regarding the tbr value only that this is some kind of refresh value that is calculated by reading the stream itself or embedded into it.
It seems like Kodi uses this value to determine the refresh rate and not the fps value.
Same behavior in version 18.4 and 18.5.
So now I wonder is this intended? If so is there a way of changing the value it uses from tbr to fps? Or could I tell my Kodi to also check for the half of the refresh rate (it already checks the double)?
I am almost sure this ends in: "There is nothing you can do your files are crap" but that would be very unfortunate.
So maybe I can do something.
Thank you very much for reading this long post and thanks in advice for any help.
