| − | [1] DeepStream SDK on Jetson uses Jetpack, which includes L4T, Multimedia APIs, CUDA, and TensorRT. The SDK offers a rich collection of plug-ins and libraries, built using the Gstreamer framework to enable developers to build flexible applications for transforming video into valuable insights. DeepStream also comes with sample applications including source code and an application adaptation guide to help developers jumpstart their builds.

| − | For this wiki used Jetson TX1 for testing. Required:
| |
| − | * Jetpack 3.2 which includes L4T R28.2, CUDA 9.0, TensorRT 3.0 GA, cuDNN 7.0.5, VisionWorks 1.6
| |
| − | * Download Deepstream for Jetson [https://developer.nvidia.com/deepstream-jetson https://developer.nvidia.com/deepstream-jetson] You need to sign and download.
| |
| − | * Deepstream download for Jetson and Tesla, available at: ftp://10.251.101.2/docs/Installers/Nvidia/

| − | '''Ridgerun''' offers GstInference, GstInference is the GStreamer front-end for R²Inference, the actual project that handles the abstraction for different back-ends and frameworks. R²Inference will know how to deal with different vendor frameworks such as TensorFlow (x86, iMX8), OpenVX (x86, iMX8), Caffe (x86, NVidia), TensorRT (Nvidia) or NCSDK (Intel), while exposing a generic/easy interface to the user.

| − | * The sample application is a Gstreamer application that uses NVidia elements, by obtaining the DOT file we can see used elements and its configurations, since decodebins and other similar elements are used the pipeline is extensive. Check the Generated Dot file at:

| − | Basically the pipeline is composed with (in order as elements appear):
| |
| − | | |
| − | * Filesrc
| |
| − | * Decodebin from mp3 to 720p NV12
| |
| − | * nvvconv
| |
| − | * nvcaffegie (this element receives as parameters profile file, caffe model and caffe model cache)
| |
| − | * nvtracker
| |
| − | * tee (with 4 outputs)
| |
| − | * Three more nvcaffegie plugins, each one with a different model (car color, vehicle type, secondary make)
| |
| − | * each one of this nvcaffegie goes into a fakesink
| |
| − | * Fourth tee goes to nvvconv
| |
| − | * nvosd
| |
| − | * nvoverlaysink
