Instruction to test about docker-nvidia-egl-desktop HOT 13 CLOSED

it worked with ENABLE_NOVNC.

Academia! Hello.
If a TURN Server is set up, it can work on Jetstream as well. It can also work if you expose enough UDP ports on OpenStack.

from docker-nvidia-egl-desktop.

In the future, our goal is to use the QUIC capacity of recent web browsers to remove that constraint.

Thank you. Do you have any performance comparisons for gstreamer vs novnc? Our intended use is realtime 3D visualization and segmentation of large 3D scan dataset on Jetstream.

GStreamer: Stable 1080p 60 fps or higher, can use NVIDIA GPUs
noVNC: You are very lucky if you can reach 15-20 fps...

Would you be able to advise us on how to set GStreamer up correctly? A100 GPUs really powerful, but would the lack of nvENC is a concern?

Argh... A100. This is a GPU that I specifically do not advise for graphical workloads. A40/A10 (of which we mainly use for the National Research Platform NSF project) are fine. But there is x264enc or vp8enc and a good CPU will cover for that NVENC deficit.

I will ask the GStreamer team if the new https://gstreamer.freedesktop.org/documentation/nvcodec/nvcudah264enc.html interface works on A100.

from docker-nvidia-egl-desktop.

But even so, this plugin will be available on GStreamer 1.22, not the current 1.20.

Jetstream is definitely something we can try our best to help on.

What about the bandwidth usage? FPS is not really all that critical (as long as we get 8-10fps, that's totally usable for our purposes). However, mouse interactions and other lag was one of the issues with VNC based solutions, particularly on slow networks.

What would be the best way to reach out for help? use this issue tracker or is there a contact we can use?

Bandwidth of Selkies WebRTC is configurable in the web interface. For 1080p, 3-4mbps should be fine on 30 fps and 8mbps-12mbps on 60 fps is optimal. I could "use" it on a cellular connection capped to 1mbps with 500kbps and 15 fps, but that is too extreme. Mouse interaction actually gets better as fps improves.

Instead of using vncserver -> noVNC or libvirt/OpenStack -> noVNC, try using Xvfb/Xorg -> x11vnc -> noVNC. I have had not much issues on that and it's pretty smooth. My container provides an example of that with NOVNC_ENABLE=true.
