Why are trying to make your life more difficult than necessary? I replaced ~70 lines of your code with just a few simple calls: /* Build the pipeline */ error = NULL; pipeline = gst_parse_launch ( "rtspsrc name=src timeout=1 buffer-mode=1" " latency=9000 protocols=GST_RTSP_LOWER_TRANS_TCP" " ! queue ! gstrtpbin latency=250" " ! queue min-threshold-time=500000" " ! rtph264depay ! ffdec_h264" " ! interlace top-field-first=true field-pattern=1" " ! videoscale add-borders=false ! videorate" " ! ffmpegcolorspace" " ! video/x-raw-yuv,framerate=25/1,format=(fourcc)UYVY" " ! decklinksink name=sink mode=2", &error); if (!pipeline) { g_printerr ("Cannot create pipeline: %s. Exiting.\n", error ? error->message : "(unknown error)"); if (error) g_error_free (error); // actually it should be a goto to free all resources // as never know when this code gets reused where it // actually matters return EXIT_FAILURE; } src = gst_bin_get_by_name (GST_BIN (pipeline), "src"); g_object_set (G_OBJECT (src), "location", argv[1], NULL); gst_object_unref (src); bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline)); gst_bus_add_watch (bus, bus_call, loop); gst_object_unref (bus); ////////////////////------------***********------------///////////////////////// and it works (I used autovideosink and <a href="rtsp://cdn.actistream.com/vod/cam1.mp4">rtsp://cdn.actistream.com/vod/cam1.mp4</a> resource). If you need more flexibility you can always refer to elements by their names as I did for "src". If the pipeline construction has to be more dynamic than at some point this approach will probably become clumsy but at least IMHO you should start with something dead simple that works (as above).

I guess you're reading documentation for GStreamer 1.0 where the format type is indeed G_TYPE_STRING and the value should be "UYVY". The FOURCC type has been refactored in GStreamer 1.0. BTW, my personal advise is to use gst_parse_launch() wherever you can which will save you time and effort as it allows you to specify pipepline description as you do on the command line. IMHO this is simpler and less error prone. You can still refer to individual elements by their name property. Construct the pipeline on a bit-by-bit basis only when it's absolutely necessary.
