It's a plugin similar to gst-omx or gst-libav, which dynamically
registers a lot of elements as available on the system. It's not easy to
guess the actual names of the elements because they depend on the name
of the codecs on your specific device.

If you use decodebin they will be used automatically if possible. Their
names start with amcviddec- and amcauddec-

Check the gst-launch code, what it does there is connecting to the
"deep-notify" signal, which causes all these things to be printed.
