When a new sink caps arrive the internal decoder state is updated and, if it is, request a downstream renegotiation. Previously, when new caps arrived the whole decoder where destroyed and recreated. Now, if the caps are compatible or has the same codec, the internal decoder is kept, but a downstream renegotiation is requested. https://bugzilla.gnome.org/show_bug.cgi?id=776979
