Issue playing clip

Issue Report

Description

I'm trying to play a clip of a local mp4 file. Though several tries, I could only get it to work if I queried the duration. I'm happy to use this as a workaround, just not clear why it is necessary.

Without the player.duration(), if I set_position then the video will not play. With the player.duration() eveyrthing works perfectly.

Problem reproduction

def playMedia(filename="demo.mp4", duration=0, position=0):
    player = OMXPlayer("/home/pi/bionic/media/" + filename, args=["--no-osd"])
    player.set_aspect_mode("fill")
    if position > 0:
        player.set_position(position)
    player.duration() # this only works if this line is here
    if duration == 0:
        duration = player.duration() - position
    player.play()
    time.sleep(duration)
    player.quit()
    return True

That's odd.

What do you mean by "get it to work", can you outline the expected behaviour and the observed behaviour before and after adding in the additional line.

Thanks

If I remove the line in question, the video simply won't play. There is no error, it just does not play. If I remove the line in question and do not set_position, the video will play (from the beginning). I just can't seem to play the video from a set position without querying the duration.
