[gst-devel] Using g_singal_emit() in GStreamer

[José Alburquerque]

Hi everyone.  I have a question about using g_signal_emit() with
GStreamer.  A user in the gtkmm list posted the following statement (see
the orignal post[1] for full context):

With gstreamer (C) we can used g_signal_emit_by_name to received the
tags. ex:

 for (i = 0; i < n_audio; i++) {
   g_signal_emit_by_name (pipeline, "get-audio-tags", i, &tags);
   ...

My question is:

How can we know which signals can be used this way?  Would all these
signals have the G_SIGNAL_ACTION flag from the GSignalFlags[2] set?
Would that be a safe way to determine which signals in GStreamer can be
used this way?  Any docs to point me in the right direction would also
be welcome.  Thanks.
