GstMeta unfortunately doesn't provide an API for
serializing/deserializing it, and for many GstMeta that also wouldn't
be possible (there are quite a few that contain pointers).

A first step for making this all work in shmsrc/sink or gdp would be to
add an optional interface on GstMeta for serialization/deserialization,
and then implement that in the GstMetas you care about.
