Me TV, playbin, and MPEG streams

Hi,

So far I have managed to make Me TV (a DVB player) without really
understanding the GStreamer pipeline that takes data from the DVB kernel
driver and delivers audio and video to the user. This is due to the wonders of
playbin. I have to fiddle with video elements and GTK+3 widgets, but with
Sebastian's guidance got something that seems to work just fine.

However, someone has asked about recording things as well as / instead of
playing them live. I am guessing the best bet is to write an MPEG-4 file in
this case and have people use Glide or Totem as the playback tool.

From my position of knowing essentially zero about what playbin is doing for
me, can anyone point me at examples (preferably in Rust, obviously :-) ) of
applications that play streams and file them at the same time? Is this sort of
thing even possible with playbin, or will I have to start manually
constructing pipelines?

I am guessing playing and recording is the hard bit, just recording without
playing should be a lot easier, but then I am not sure I want to get into all
that PVR stuff, people have PVRs and Web streaming for all that.
