Probably but I can't remember any right now. It's very simple though.

You just get the value of the "last-sample" property at any time you
want to take a snapshot, and then pass the sample you receive to
gst_video_convert_sample(). As a parameter this also takes the caps you
want to convert it to, so you could pass in caps for "image/png" for
example.

The resulting GstSample this returns will then contain a buffer of the
format you specified via caps.
