Please, quote exact error messages in full. This is obviously a C warning,
not a vala error, right? Just ignore it.

Whenever you get incompatible pointer types warning from C compiler, it is
spurious unless you are actually debugging the .vapi file (in which case it
might mean you have declared the delegate type incorrectly).

In this case it's actually a bug on gstreamer side, because they actually do
expect 'gboolean (*)(struct GstPad *, struct GstBuffer *, void *)' but they
declared it a GCallback for unknown reasons.
