Changelog:
- Fix Audio / Video Sync when "Sync Playback to Display" is disabled, e.g. when users use passthrough.
- Fixup Adjust Refreshrate to match video. We now also can change resolutions, use case: Gui @ 1080p60 -> switch to 4k@24 when a matching movie, e.g. refreshrate is 24 is to be played. This is especially a use case for Intel Boxes that can only output 4k@30 max and therefore LiveTV content (1080i50) should be played at 1080p50. Note: if you have such a setup, we recommend to run the GUI in 1080 mode as kodi's GUI scaler is just low quality. It will automatically switch up when content is played which fps <= max refreshrate at 4k.

Fernet just pushed 5 minutes ago, I did not get the change by spiff to load ffmpeg tags, so for dsf and mka tags you need to wait until tomorrow.

Thanks fritsch for this build. I play a little with the new "Adjust Refreshrate".

My review for this first try :
GUI set to 1080p60 -> no problem switching between GUI and videos is OK
Now for the videos:
all 24 fps videos are displayed at 4096x2160@24
all 25 fps videos are displayed at 1920x1080@50
all 30 fps videos are displayed at 2560x1440@60
all 50 fps videos are displayed at 1920x1080@50
wathever the resolution !
e.g 3840x2160@50 -> 1920x1080@50 and 640x360@24 -> 4096x2160@24

Displaying 360p videos at 2160p is a bit annoying with bilinear upscale ( lanczos and others give drop and skip ) and the TV upscale give better result.
Could it be possible to display only 4k videos at 4k resolution and leave 360p,480p,1080p at 1080p resolution ?
Also 3840x2160@25 videos are displayed at 1920x1080@50 but I have a 3840x2160@25 mode, Isn't it better to use the native framerate at full resolution ?
