Random notes on signals:
|
||
|
|
|
||
|
|
* Use a BOXED (and not a POINTER) marshaller when your signal will have a
|
||
|
|
GstBuffer argument:
|
||
|
|
|
||
|
|
g_signal_new ("handoff", G_TYPE_FROM_CLASS (klass), G_SIGNAL_RUN_LAST,
|
||
|
|
G_STRUCT_OFFSET (GstIdentityClass, handoff), NULL, NULL,
|
||
|
|
gst_marshal_VOID__BOXED, G_TYPE_NONE, 1,
|
||
|
|
GST_TYPE_BUFFER | G_SIGNAL_TYPE_STATIC_SCOPE);
|
||
|
|
|
||
|
|
* For GstBuffers arguments, consider using G_SIGNAL_TYPE_STATIC_SCOPE as it
|
||
|
|
can prevent an extra copy of the buffer
