How to add a “capsfilter” element to a “playbin”, here “playbin” is created from gst_element_factory_make() API .

[sandip]

I want to add a “capsfilter” to a playbin.
Step 1. I am creating “capsfilter” using API gst_element_factory_make(“capsfilter”,”myfilter”).
GstElement  *myAudioFilter    = gst_element_factory_make( "capsfilter", "audiofilter" );
Step 2. Then I am creating my own audiofilter/cap,
g_object_set (G_OBJECT (MyAudioFilter), "caps",
                gst_caps_new_simple ("audio/x-raw-int",
                "rate",       G_TYPE_INT, SampleRate,
                "channels",   G_TYPE_INT, 2,
                "depth",      G_TYPE_INT, 16,
                "width",      G_TYPE_INT, 16,
                NULL), NULL);
Step 3. I already created a pipeline ,
GstElement *myplaybin = gst_element_factory_make(“playbin”,”plbn”);
My query is How can I add my created capsfilter (MyAudioFilter) to factory make playbin (myplaybin) ?
