- use displays refresh rate - execute needs drawing with higher priority - run create() with higher priority - determine the number of threads used for rendering - enable VSYNC and change video-sync to display-resample - iOS/tvOS: set new display refresh rate on change - run setSize with higher priority - add more options to MPVClient - get refresh rate updates - sync refresh rate to fps - update CADisplayLink to current refresh rate - update refresh rate on macOS - Add experimental feature to sync display with content fps Signed-off-by: Toni Förster <toni.foerster@gmail.com>
