Software Solution

On Jetson, there are mainly three software solutions:

1. Multimedia Low Level API

> Multimedia Low Level API provides V4L2 APIs to operate the Jetson SOC HW accelerators, i.e. NVENC, NVDEC, Display, VIC, Camera, etc 
> Doc : https://docs.nvidia.com/jetson/l4t-multimedia/index.html  
> Sample code: /usr/src/jetson_multimedia_api/   , on Jetson device

2. DeepStream

> DeepStream is a GStreamer based framework. User can implement their application quickly by some configuration or few modification 
> Doc: https://docs.nvidia.com/metropolis/  
> DeepStream Code: /opt/nvidia/deepstream/ , on Jetson device after you installed DeepStream
> DeepStream is installed via SDKManager or downloaded from https://developer.nvidia.com/deepstream-getting-started, and install it following https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_Quickstart.html#install-jetson-sdk-components

3. GStreamer

> NVIDIA provides many GStreamer plugins for Jetson HW accelerators, e.g. NVDEC. NVENC, VIC(video image converter), Display/Render and so on 
> User can use these plugins along with the other non-NVIDIA GST plugin for the application development 
> Jetson GStreamer plugin document - https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/accelerated_gstreamer.html  
> All NVIDIA GST Plugins are installed on Jetson device via SDKManager 

Note: not all NVIDIA GStreamer plugins can be used in DeepStream. About this, refer to this FAQ
