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));
