Recommended interface between camera and VisionWorks or VPI

[_martin]

Hi there,
I’m working on an image stitching pipeline that requires very low latency from camera to display.
There are various ways of getting images from a camera as Nvidia describes in the camera architecture stack doc. In my currently conceptual (low) understanding this is V4L2, Gstreamer with libargus backend, Eglstream with libargus backend.
On the processing side you have VisionWorks and upcoming VPI.

What are recommended efficient ways of connecting the camera with the VisionWorks and VPI processing libraries?

For instance, Libargus is designed to output to Eglstreams. Do you have code samples of how to connect VisionWorks or VPI with Eglstreams?

br, Martin

Hi,
We would suggest use VPI. You may refer to this topic:

Writing a custom Gstreamer plugin

Someone who can guide me in writing a custom GSttreamer plugin. I want to make a custom plugin using the VPI library for dewarping. I tried the gst-dsexample to start with, but ran into quiet a bit of problems As soon as I renamed the plugin and tried to install it, it ends up in the blacklist of plugins I want to use nvarguscamerasrc as the src in the stream passing NV12 data into this plugin Any guidance and/or experience is appreciated /Fredrik
