QtGstreamer build under Windows

Sat Jun 20 02:36:54 PDT 2015

I dont know what to use instead of QtGstreamer lib, to resolve my problem.
I have udp gstreamer video as source, on receiver Windows PC i need to grab
current stream and use with opengl fragment glshader and use video as
texture. How can i do that using only Qt without QtGstreamer bindings?

Regards, Dmitri
