**• DeepStream Version 6.x** This sample is modified from deepstream-test3. User can use VLC to watch this rtsp stream remotely. User should install gstreamer rtsp server first. ```auto sudo apt-get install libgstrtspserver-1.0 libgstreamer1.0-dev ``` First you can check you environment is ready for rtsp streaming. Copy the rtsp server example [here](https://github.com/GStreamer/gst-rtsp-server/blob/1.14.5/examples/test-launch.c) and compile this file. ```auto gcc test-launch.c -o test-launch $(pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-server-1.0) ``` Then start the test rtsp server. Note this command did not use `nvvidconv` and `nvv4l2h264enc` element like the reference post because it will cause a broken pipeline _ **without any error** _ in dGPU environment. ```auto ./test-launch "videotestsrc is-live=1 ! videoconvert ! x264enc ! h264parse ! rtph264pay name=pay0 pt=96" ``` Then you can start a client using VLC connect to `rtsp://:8554/test`. If it fail to connect, start a client in the same computer in another termal by ```auto gst-launch-1.0 uridecodebin uri=rtsp://127.0.0.1:8554/test ! fakesink ``` If success, the program will keep running without error. After check the environment is OK, you can build the modified deepstream-test3 code in attachment. After compile the code, change the `source-list:` in `dstest3_config.yml`. Run the app with command ```auto ./deepstream-test3-app dstest3_config.yml ``` and use VLC connect to `rtsp://:8554/ds-test` then you can see the stream. This example code copy functions `start_rtsp_streaming`, `client_filter`, `destroy_sink_bin` from `/opt/nvidia/deepstream/deepstream/sources/apps/apps-common/src/deepstream_sink_bin.c` The main idea is deepstream pipeline stream go to udp sink on 5400 port, and then we start a rtsp server using `start_rtsp_streaming`. This rtsp server receive the udp as source and turn it into rtsp stream.

OK, So we first check if you can open the RTSP stream in the same computer. Are you sure you run the command `gst-launch-1.0 uridecodebin uri=rtsp://127.0.0.1:8554/test ! fakesink` and `./test-launch "videotestsrc is-live=1 ! videoconvert ! x264enc ! h264parse ! rtph264pay name=pay0 pt=96"` in the same computer (the remote server)?

It’s necessary to say that [deepstream-test1-rtsp-out](https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/tree/master/apps/deepstream-test1-rtsp-out) works properly. This example has been written in python. ---
