plugin to add meta data right after capture

I'm trying to add custom metadata to my pipeline as early as possible so it
matches the capture video frame as closely as possible. (so i can add GPS
location, speed, direction)

>From what i've read creating a plugin that has gstbasetransform (
would be the best match.

Is this correct ? Or is gstbasetransform for modifying metadata only , not
adding new metadata ?
If so, which base class should I look at , and which function
pointer/callback would be the best to add new metadata ? (
copy_metadata , transform_meta,
kind regards
