I need the statistics that are available on the stream object in a gstreamer pipeline. The stream was not accessible from the element.
To access the stream, I add a
stream
property. Since this property receives value at set_caps when the pipeline is prepared, I need to be notified of the new stream. For that I need to be able to connect tonotify::stream
signal.I add the signal emission for both
camera
andstream
properties as they both seem to change value by themselves.
