MediaFileSignalName

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

(C Language Example):

g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

It is important to note that you must use canonical parameter names as detail strings for the notify signal.

The stream’s duration in microseconds or 0 if unknown.

Set when playback has finished.

nil for a properly working stream or the GError that the stream is in.

The file being played back or nil if not playing a file.

Whether the stream contains audio.

Whether the stream contains video.

The stream being played back or nil if not playing a stream.

This is nil when playing a file.

Try to restart the media from the beginning once it ended.

Whether the audio stream should be muted.

Whether the stream is currently playing.

Whether the stream has finished initializing and existence of audio and video is known.

Set unless the stream is known to not support seeking.

Set while a seek is in progress.
