Using a GPU for dispaying IP cameras in vision

Ignition
1

Hi, I would like to know how to set Ignition to use my server's GPU? We have configured multiple IP cameras (30 in total, but only 6 - 8 live on one window at a time) that need to stream video to the operator, and currently the video is lagging. So we are thinking of transferring the application to a beefy server that has a GPU that is not currently used. The server is currently used for other image processing and control functions, so I don't want the Ignition to use all the CPU. Is there a setting somewhere to transfer the video streaming to the GPU?
It is an NVIDIA Ampere GPU

The video is lagging on the client, during display? Hardware on the gateway won't make any difference, and GPU hardware on the client probably won't make any difference either; Java Swing is generally CPU-only. Especially if you're directly using our IP Camera component, which manually deals with image data in Java code.

If the video is lagging due to server transcoding or something, it's possible different gateway hardware would help, but I doubt that's actually your problem or that it's going to help, unfortunately.

You'll just have to reduce the quality of the stream to be able to handle multple videos at once

We had to define ignition specific stream profiles in our cameras to be able to reduce cpu overusage in the client.
Quality is a bit lower but at least, it's smoother.

Basically, on the cameras, we reduced the resolution, upped the compression and reduced the image rate. On Vision, if I remember correctly, we played with the buffer size.

You can try to go Perspective for this issue but you might encounter issues if you connect in https to your project but the cameras can only handle http : Perspective Video Stream http and https mixed content

If the clients are lagging, there's really only two knobs to tweak:

  • Reduce the resolution of the MJPEG stream. (My Image Streamer module will help you do this at the gateway for many consumers at once, instead of in the camera.)

  • Turn off scaling in the IP Camera Viewer component.

Java Swing does not use any local GPU.

Hi Pturmel - can you provide me with a link to My Image Streamer) - what is the cost?
