flickering in the area of the videoclip.

https://www.dropbox.com/s/co6frgbaxaisdmi/Crossfade.m4v?dl=0

2.Play the presentation full screen


Actual Results:

clear flickering instead of a smooth crossfade transition among frames.

Expected Results:

The video plays without flickering if played during edit mode of the slide, or
with libreoffice's internal player.
