I think I found why the patch wasn't working with reverse at low speed,
I changed it (file openshot-diff).

But I'm not able to see the video neither. I guess the player does not
manage reverse video at low speed.

I tried with a cutted clip of 15 seconds, output timestamps seem good
but I get a white windows when I try to play the video :

Bug description:
## Problem with speed :

  Length of a video part does not update when I want to play it slower.

  I needed to comment some part of the code to make it working :

  openshot-1.2.2/windows/ClipProperties.py : 808
    ##if speed_multiplier < original_speed:
      # clip is longer now (keep the short version)
      ##clip_object.end_time = clip_object.start_time + original_length
    ##else:
      # clip is shorter
    clip_object.end_time = new_end_time


## Problem with reverse :

  When I want to play a part of a video in reverse, it does not keep the good part of the video
  I changed a part of the code :

  openshot-1.2.2/windows/ClipProperties.py : 813
    if localcboDirection.lower() == _("Reverse").lower():
      clip_object.reversed = True
      tmp = clip_object.start_time
      clip_object.start_time = clip_object.max_length - clip_object.end_time
      clip_object.end_time = clip_object.max_length - tmp
    else:
      clip_object.reversed = False

But I'm not too good in coding... it works but only at normal speed. when I want to make it slower, I have an other part of the video again
