You should probably contact the application developer to start with. I
suspect that the capture is done using libusb, and only certain device
(need USB host support) and chips are supported (seems like UTV007 and
STK1160). If you bought the SW, you are allowed to request the LGPL
source code being used. That could also tells you a bit about what is
being used in GStreamer. It is possible, and completely legal, if the
capture code was kept proprietary. It's the "hard" part to be honest,
not everyone will be willing to give this away.

There is kernel drivers that landed in 3.14, and to experiment, a
libusb version was made in python to for the UTV007:
