Hi guys,
first up my system:
Linux Mint 17.3 Mate
Intel Pentium 4400
Nvidia GeForce 950
Kodi 16.1 Jarvis
Screen: 3840x2160 @ 60p (4k)
Good:
To avoid stuttering I enabled the option "Change Display Refresh Rate at Start/Stop" so it best matches any video file's frame rate.
Example:
My PC boots up and starts with 60p for desktop use, I launch Kodi and watch a movie with 23,975p and Kodi changes the refresh rate of the display accordingly - the movie looks very smooth and everything is fine.
Problem:
BUT when I watch a movie witch has a 25p frame rate Kodi does something odd: It changes the display refresh rate to 50p. Obviously there is a mismatch and the video is stuttering. I checked by pressing "O" during playback and I could confirm that the display runs at 50p while the movie only delivers 25p. There are skipped frames which cause the stuttering.
I also checked the log-file: Kodi recognises the movie goes with 25p, but it calls XRANDR (the display manager) and sets 50p for the display.
And another thing I tried: I disabled the Kodi automated refresh-rate change option; closed Kodi and called XRANDR manually to force my display to 25p, then I launched Kodi again and watched the same movie file that comes with 25p: Guess what, it was smooth as butter!
My guess for a solution would be: I should change the value from 50p to 25p when facing a 25p movie file, but i don't know how.
Is this a well known bug; is there a fix? Please help!
