        <div>On my PC, I can run "gst-launch-1.0 videotestsrc pattern=1
          ! video/x-raw, width=1920, height=1080 ! autovideosink" to get
          correct result.</div>
        <div>But, if I use C language to write a sample code, not
          using gst_parse_launch, how can I set capabilities for
          videotestsrc? Thanks.</div>
        <div>caps  = gst_caps_new_simple ("video/x-raw",  <br>
                      "width", G_TYPE_INT, 1920,<br>
                       "height", G_TYPE_INT, 1080,<br>
                       "framerate", G_TYPE_INT, 60,<br>
                       NULL);<br>
