Getting Error for nvv4l2h264enc in application compilation

Hi,
You should not need to use DeepStream SDK in this usecase. Please try the following sample:

#include <cstdlib>
#include <cstring>
#include <sstream>
#include <gst/gst.h>

using namespace std;

#define USE(x) ((void)(x))

static GstPipeline *gst_pipeline = nullptr;
static string launch_string;

GstClockTime usec = 1000000;
static int w = 640;
static int h = 480;

int main(int argc, char** argv) {
    USE(argc);
    USE(argv);

    gst_init (&argc, &argv);

    GMainLoop *main_loop;
    main_loop = g_main_loop_new (NULL, FALSE);
    ostringstream launch_stream;

    launch_stream
    << "v4l2src name=mysource ! "
    << "video/x-raw,width="<< w <<",height="<< h <<",framerate=30/1,format=YUY2 ! "
    << "nvvidconv ! nvv4l2h264enc ! h264parse ! qtmux ! "
    << "filesink location=a.mp4 ";

    launch_string = launch_stream.str();

    g_print("Using launch string: %s\n", launch_string.c_str());

    GError *error = nullptr;
    gst_pipeline  = (GstPipeline*) gst_parse_launch(launch_string.c_str(), &error);

    if (gst_pipeline == nullptr) {
        g_print( "Failed to parse launch: %s\n", error->message);
        return -1;
    }
    if(error) g_error_free(error);

    gst_element_set_state((GstElement*)gst_pipeline, GST_STATE_PLAYING); 

    g_usleep(15*usec);

    GstElement* src = gst_bin_get_by_name(GST_BIN(gst_pipeline), "mysource");
    gst_element_send_event (src, gst_event_new_eos ());
    // Wait for EOS message
    GstBus *bus = gst_pipeline_get_bus(GST_PIPELINE(gst_pipeline));
    gst_bus_poll(bus, GST_MESSAGE_EOS, GST_CLOCK_TIME_NONE);

    gst_element_set_state((GstElement*)gst_pipeline, GST_STATE_NULL);
    gst_object_unref(GST_OBJECT(gst_pipeline));
    g_main_loop_unref(main_loop);

    g_print("going to exit \n");
    return 0;
}

Build command:

$ g++ -Wall -std=c++11  test.cpp -o test $(pkg-config --cflags --libs gstreamer-app-1.0)

We run it with Logitech C615 which supports 640x480p30 YUYV.

Please refer to FAQ
Q: I have a USB camera. How can I lauch it on Jetson Nano?
and configure support mode to video/x-raw,width,height,framerate,format.
