[gst-devel] Composing Caps - Where can I put a code sample?

[HaroldJRoth]

Any suggestions on where I'd put this code sample?  

For newbies who learn from copy/paste/modify, I think its useful, as it took
me a while to figure it out.  (Feel free to correct)

	// Bland caps specification
	//
	LOG_INFO(TAG_GSTREAMER, "Create videoCaps for our input.");
	GstCaps* videoCaps = gst_caps_new_simple("video/x-raw-yuv", "format",
			GST_TYPE_FOURCC, GST_MAKE_FOURCC('I', '4', '2', '0'), NULL);

	// Idiom for tightening a caps specification.
	//
	LOG_DEBUG(TAG_GSTREAMER, "VideoCaps for our input was: %s \n",
			gst_caps_to_string(videoCaps));
	GstStructure *cs = gst_caps_get_structure(videoCaps, 0);
	gst_structure_set(cs, "width", G_TYPE_INT, 320, "height", G_TYPE_INT, 240,
			NULL);
	LOG_DEBUG(TAG_GSTREAMER, "VideoCaps for our input is NOW: %s \n",
			gst_caps_to_string(videoCaps));
