Could we use `GST_ERROR` / `GST_WARNING` for these messages instead of `fprintf` like for all the other messages printed from the unix side?

The reason I didn't is because GST_ERROR output isn't printed by 
default, even at the highest severity. GST_MESSAGE_ERROR and 
GST_MESSAGE_WARNING are by contrast meant to be user-visible; they're 
printed from gst-play-1.0 for example.

In practice I think we at least want to make sure that "missing decoder" 
messages are printed.
