This example demonstrates how to use the Video API routines to communicate with a video device, and encode/decode the data.

You would use this example if you needed a node to talk directly to a video device, and didn’t want to use the generic-video-device driver, which supports all V4L USB video devices. It connects to a USB webcam (that must be Video4Linux (V4L) compatible), encodes the sensor data, and then decodes the same image stream to show the image processing pipeline. This DOES NOT connect to a node defined in the SDF, it connects directly to the hardware device using the Video API. It expects XXXXX pixel format

Sensors: LiDAR, RADAR Video Device

Packages: libglib2.0-dev libgstreamer1.0-0

To install on Ubuntu:

sudo apt-get install libglib2.0-dev libgstreamer1.0-0

$ cd VideoDeviceViewer 
$ mkdir build && cd build
$ cmake ..
$ make
$ ./polysync-video-encode-decode-cpp
