is_ready

Returns whether the pipeline is ready and so clutter_gst_video_sink_get_pipeline and clutter_gst_video_sink_setup_pipeline can be called without causing error.

Note: Normally an application will wait until the pipeline_ready signal is emitted instead of polling the ready status with this api, but sometimes when a sink is passed between components that didn't have an opportunity to connect a signal handler this can be useful.

Parameters:

this	The VideoSink

Returns:

true if the sink is ready, else false
