I have started looking into dispmanx code. will try this.

I thought glcolorscale is also used for scaling the video so i was thinking
of using it to change the width and height of video to match screen
resolution to play it in fullscreen. But anyway i think right way to play in
full screen is by using dispmanx API and to create GstVideo overlay.
 
I will try this today.

I had one more question related to gst_player.. Is there any api to change
the a aspect ratio of the video ? 

Thanks & Regards
