Thanks for the rapid feedback!
The method you suggest runs, but the output is not consistent with the output from:
gst-launch-1.0 videotestsrc num-buffers=1 ! video/x-raw, format=P010_10LE ! filesink location=output.raw
Inspecting the pads during operation, I can see that the data is transformed to video/x-raw format=I420 as an intermediate step, thus removing 2 bits of information.
Do you have a solution for this?
Answer to your question: I have constructed the same pipeline in Python using the PyGobject library so that I can inspect the pads using gst probes.
My output from gst-inspect-1.0 nvvidconv is:

Which suggests that video/x-raw, format=P010_10LE should be available, but I might interpret it wrong?
