Can you please share your confit.txt file also ?

I am using Buildroot based image. Will update the .mk to take latest one and
try. 
But omxplayer plays FULL HD smoothly, so this should not be the case right ?

I am using latest versions (1.9.90) of gstreamer and gst-omx. Let me check
how buildroot configures gst-omx. If it configures differently then i can
modify the files to use above configure options.

Yes.

Let me check this and get back to you.

I can confirm that in my case it uses glimagesink. 

Thanks for your suggestion I will try everything and get back to you.

Thanks & Regards
