Not really. The GST_DEBUG=basesink:6 log should tell you, or QoS events
sent upstream for each buffer (if qos is enabled like it it for video
sinks, but you can also enable it on fakesink with qos=true).

You could also set up a pad probe and a pad idle probe and measure the
time it takes from the buffer going into the sink and your idle probe
being called (although that would include the time it took to render as
well then).
