Getting GigE into V4L2

Using Aravis
1

Hi,

Aravis works great, i can see my stream, very cool.

I need to get the perfect video I see in Aravis into a face tracker for games, opentrack is the main one, I think that needs V4L2.

I’m on nixos but everything Gemini/ChatGPT/Claude suggested is broke. I may have to do a different distro maybe using distrobox.

Please help.

Thanks.

Hi,

I have just taken a look at opentrack, and its neural network tracker. It seems based on openCV, which to my knowledge should be able to acquire a video stream from aravis.

If v4l2 is actually the only possible source, you may try to use aravis gstreamer plugin and v4l2sink, that would simulate a v4l2 device using aravis video stream.

Emmanuel.
