None of them do and it IMHO doesn't make sense for identity. But
compositor's sinkpads do, and you can just set the pad offset on them.
But as always, gst-launch is a debugging and testing tool. Write your
application in a real programming language if you want to do such

Well I need to introduce the offset upstream of a compositor.I can always introduce a second compositor (with a single source) just to benefit from the fact that it exposes the pad offset to gst-launch (which I have to use at this stage...).Not very elegant but could work.
Is it correct to say that, ideally, all elements should implement GstChildProxy and expose pad properties to gst-launch ?
Is that in line with a hypothetical long term road map or would it just be plain stupid ?
