Gst.Bin.prototype.find_unlinked_pad

function find_unlinked_pad(direction:Gst.PadDirection):Gst.Pad {
    // Gjs wrapper for gst_bin_find_unlinked_pad()
}

Recursively looks for elements with an unlinked pad of the given direction within the specified bin and returns an unlinked pad if one is found, or NULL otherwise. If a pad is found, the caller owns a reference to it and should use Gst.unref on the pad when it is not needed any longer.
