    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!

      Hi,

      Please do not post the same question on multiple sub-forum.

      One is enough
