*
* Get a message from the bus whose type matches the message type mask @types,
* waiting up to the specified timeout (and discarding any messages that do not
* match the mask provided).
*
* If @timeout is 0, this function behaves like gst_bus_pop_filtered(). If
* @timeout is #GST_CLOCK_TIME_NONE, this function will block forever until a
* matching message was posted on the bus.
*
* Returns: a #GstMessage matching the filter in @types, or NULL if no matching
