Do we have support in GStreamer (or elsewhere) for this?

I believe you wanted to ask for patched framework to exercise this ? Since both
FFMPEG and GSTreamer have had that format for ages. For GStreamer:

https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/blob/master/gst-libs/gst/video/video-format.h#L102

No V4L2 mapping upstream, but this is a bit normal, can't upstream a mapping for
something that does not exist yet.

Thanks,
Ezequiel
