## Prerequisites

- Enable `wlan0`. For instructions, see [How to SSH?](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-254/how_to.html#how-to-ssh-)
- After reboot, the Wi-Fi should be up and running.

        ifconfig   // Note down wlan0_IPCopy to clipboard
- To configure HTTP use cases, select an unused
                    port:

        vi /etc/default/gstd
             OPTARGS=" --enable-http-protocol --http-address=wlan0_IP --http-port=5002"       // Replace the port 5002 if the port is not free
        
             XDG_RUNTIME_DIR=/dev/socket/weston
        
             WAYLAND_DISPLAY=wayland-1
        
        systemctl daemon-reload
        systemctl restart gstdCopy to clipboard
- Download [Postman](https://www.postman.com/downloads/) to run the HTTP use cases.

##  Single stream encode

1. Create the pipeline -
                    POST:

        http://10.92.160.147:5002/pipelines?name=pipeline_http_enc1&description=qtiqmmfsrc name=camsrc ! video/x-raw(memory:GBM),format=NV12,width=1920,height=1080,framerate=30/1,compression=ubwc,interlace-mode=progressive,colorimetry=bt601 ! v4l2h264enc capture-io-mode=5 output-io-mode=5 ! h264parse ! queue ! mp4mux ! queue ! filesink location=/tmp/http_enc1.mp4Copy to clipboard
2. Control the pipeline:
    - Play the pipeline -
                            PUT:

            http://10.92.160.147:5002/pipelines/pipeline_http_enc1/state?name=playingCopy to clipboard
    - Send
                            EOS:

            http://10.92.160.147:5002/pipelines/pipeline_http_enc1/event?name=eosCopy to clipboard
    - Stop the pipeline -
                            PUT:

            http://10.92.160.147:5002/pipelines/pipeline_http_enc1/state?name=nullCopy to clipboard
