Glad you resolved that problem, it definitely required a bit of
investigation. If your element is just a decoder, it would be best to use
the base class, GstVideoDecoder, as it handles many important details for
you.

As for autoplugging in something like decodebin, you need to implement a
typefinding function, and then make sure the rank (GstRank) is high enough
to be preferred over any other decoders that can handle the same format:
