QMediaPlayer setPosition() weird behaviour

sssupply

Hello,

I am using QMediaPlayer to display a video and I have a step forward button that is supposed to move the video one frame forward.
Here is the step forward function:

def next_frame(self):
           self.progress_slider.setSliderPosition(self.progress_slider.value() + self.frame_increment_interval)
           self.player.setPosition(self.player.position() + self.frame_increment_interval)
           return

but when I click the button it shows a previous frame first (like 100 frames in the past) before it moves to the next frame.
Any idea why this behaviour exists?

Thanks!
