which docs is valid?

[Farkas Levente]

hi,
there're two docs about appsink:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-appsink.html#GstAppSinkCallbacks
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-appsink.html#GstAppSink-new-buffer
the first one said the "new-buffer" return void while the second
GstFlowReturn.
which one is the right?
the same question true for many other signal in appsink and appsrc.
thanks.
