# RTSP Cameras

- Refer to the following pipeline for RTSP camera and modify the appropriate `config.json` file
in `[WORKDIR]/edge-ai-libraries/microservices/dlstreamer-pipeline-server/configs` directory.

```sh
  "pipeline": "rtspsrc location=\"rtsp://<USERNAME>:<PASSWORD>@<RTSP_CAMERA_IP>:<PORT>/<FEED>\" latency=100 name=source ! rtph264depay ! h264parse ! decodebin ! videoconvert ! video/x-raw,format=RGB ! appsink name=destination"
```

> **Note:** The RTSP URI of the physical camera depends on how it is configured using the camera
> software. You can use VLC Network Stream to verify the RTSP URI to confirm the RTSP source.

> **Note:**  If you are deploying DL Streamer Pipeline Server behind proxy environment, make
> sure that <RTSP_CAMERA_IP> address is specified under `no_proxy` environment variable.

> **Note:** For more information on the RTSP URI please refer to the website/tool of the camera
> software which is used to configure the RTSP camera.

**Simulating RTSP streaming Cameras**

- Start RTSP using open source RTSPATT docker image
  - Run the following command to create a RTSP stream:

    ```sh
    docker run --rm -e RTSP_RESOLUTION='1920'x'1080' -e RTSP_FRAMERATE=25 -p 8554:8554 ullaakut/rtspatt:latest
    ```

  If more options are required to generate a RTSP stream refer
  the following link:
  <https://hub.docker.com/r/ullaakut/rtspatt/>


- Start cvlc based RTSP stream
  - Install VLC if not installed already: `sudo apt install vlc`
  - In order to use the RTSP stream from cvlc, the RTSP server must be started using VLC with the following command:

        `cvlc -vvv file://<absolute_path_to_video_file> --sout '#gather:rtp{sdp=rtsp://<SOURCE_IP>:<PORT>/<FEED>}' --loop --sout-keep`

> **Note:** `<FEED>` in the cvlc command can be `live.sdp` or it can also be avoided. Ensure
> the same RTSP URI given here is used in the ingestor pipeline config.
