How can I set capabilities on videotestsrc?

[Psychesnet Hsieh]

Hi all,

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.

But, if I use C language to write a sample code, not using gst_parse_launch, how can I set capabilities for videotestsrc? Thanks.

caps  = gst_caps_new_simple ("video/x-raw",  
            "width", G_TYPE_INT, 1920,
             "height", G_TYPE_INT, 1080,
             "framerate", G_TYPE_INT, 60,
             NULL);

Insert a capsfilter element after videotestsrc and set the caps on that using g_object_set (capsfilter, "caps", caps, NULL);
