OpenGL: Is it possible to store a 'glimagetransformation applied' video to a file?

[vk_gst]

Hi Mazdermind,


So this is what I tried based on your suggestion: 

intervideosrc ! glupload ! glcolorconvert ! gltransformation ! gldownload !
video/x-raw ! videoconvert ! x264enc ! mp4mux ! filesink location=abc.mp4

In the above case, the file is created but when I open it there's nothing
that is displayed. I have the above pipeline in a python script which I
execute using: 
     $./script.py -e  


I have checked the capabilities of the elements used in the pipeline and
they seem to be all compatible. 
Do you see where I am going wrong? 

Regards
