Getting data from buffer to pass to another function/process outside of Gstreamer

before the encoder and wait for the handoff signal to fire. This callback
will get you a reference to the GstBuffer that is about the pass the
identity element. You can use gst_buffer_extract to extract the data from
the buffer and do what you want.

Alternatively, you can split the pipeline in two, use appsink and wait for
its callback:
