[Intel-gfx] Placement and cropping of video due to aspect ratio mismatch

[Jyotsana]

Hi,

I am playing video using "libva-1.0.7" and gstreamer-vaapi plugin.
A window is created and passed to the plugin so that video is rendered 
on it.
There is an observation if the aspect ratio of the window is different 
from the aspect ratio of the video,
then some videos are aligned with top edge of the window, some appear in 
the middle and
some aligned with the bottom edge of the window.
A particular video always gets rendered at the same location.
In some cases, the video is getting cropped.
I am not sure whether this is handled by the plugin or the driver.
Is this behaviour known.

Thanks and Regards,
Jyotsana.
