DEEPSTREAM SDK ON JETSON (PRE-RELEASE)
QUICK START GUIDE

  1. run JetPack 3.2,and we will be ready to install and run DeepStream SDK on Jetson.

  2. Copy the DeepStream SDK on Jetson archive file to /home/nvidia/Downloads/DeepStream_SDK_on_Jetson_1.5_pre-release

  3. Extract the contents:

$ tar xpvf DeepStream_SDK_on_Jetson_1.5_pre-release.tbz2

Extract the DeepStream SDK on Jetson software into the file system:

$ sudo tar xpvf deepstream_sdk_on_jetson.tbz2 -C /
   $ sudo tar xpvf deepstream_sdk_on_jetson_models.tbz2 -C /

Execute the following command on the Jetson development board:

$ sudo ldconfig
  1. Confirm that the DeepStream installation is successful by executing
    this command on the Jetson development board:
$ nvgstiva-app -c ${HOME}/configs/PGIE-FP16-CarType-CarMake-CarColor.txt

We will see the file:///home/nvidia/sample_720p.mp4 which be note in

/home/nvidia/configs/PGIE-FP16-CarType-CarMake-CarColor.txt like this

[source0]
enable=1
#Type - 1=CameraCSi 2=CameraV4L2 3=URI
type=3
camera-width=1920
camera-height=1080
camera-fps-n=30
camera-fps-d=1
camera-csi-sensor-id=0
camera-v4l2-dev-node=0
uri=file:///home/nvidia/sample_720p.mp4
  1. So, if we want to use the onboard Camera, let the type be 1
#Type - 1=CameraCSi 2=CameraV4L2 3=URI
type=1

then run

$nvgstiva-app-gui -c ${HOME}/configs/PGIE-FP16-CarType-CarMake-CarColor.txt      -g ${HOME}/configs/gui_cfg.txt

if you can see something like this, you will have a smile.
