Nicolas, I knew this is a hack.. We did this hack for v4l2src sometimes back to
support a customer when gstreamer-vaapi was not the part of upstream :).. There
was no proper dmabuf negotiation capabilities at that time too. 
As I mentioned in the commit message we will get-rid of this hack once we have
a fix for https://bugzilla.gnome.org/show_bug.cgi?id=755072 .
