Tag reading is remarkably simple in GStreamer Every element supports
the "found-tag" signal, which will be fired each the time
the element reads tags from the stream. A GstBin
will conveniently forward tags found by its childs. Therefore, in most
applications, you will only need to connect to the
"found-tag" signal on the top-most bin in your pipeline,
and you will automatically retrieve all tags from the stream.
Note, however, that the "found-tag" might be fired multiple times and by multiple elements in the pipeline. It is the application's responsibility to put all those tags together and display them to the user in a nice, coherent way.
