A while ago (actually almost a decade!) I added caps-passing to
shmsink/shmsrc when I ported it to windows (
didn't seem to garner interest so I never put in a merge request. We've
since created another shared memory plugin for Linux and Windows with
Python bindings, all with auto caps handling.
I'm guessing you're on Linux, but note that the new win32ipc plugin
supports automatic caps handling.
Otherwise, I'm not sure what would work for you. If you are interested in
the patch for caps-handling in shmsink/shmsrc, let me know.
