The same problem should be encountered on branch experimental_9.0.
What version of GStreamer are you building with? Probably before 1.22?

You're right. I built it on github's Ubuntu, GStreamer version 1.20.
The type is introduced in 1.22, so try a newer distro version https://gstreamer.freedesktop.org/documentation/gstreamer/gstbuffer.html?gi-language=c#GstBufferMapInfo
Okay, thanks for the instructions.
Nothing extracted yet.
