Emulate a USB camera from computer vision output both internally (v4l2loopback) and externally (as usb slave device)

Unfortunately those applications won’t directly run on on arm64 for Linux (the arm64 they have is for Android). So you do need something like what @Andrey1984 suggests.

An alternative is to create some sort of streaming service on the Jetson, and an adapter software on the host PC to make the stream appear to be a camera. Either way you’d be emulating a camera, but I think emulating a camera on the host PC has a better chance than emulating a camera on the Nano. The Nano should be quite good with something streaming, e.g., v4l2 or RTSP, but to emulate a camera over USB on a Jetson is going to have some issues. I really suggest looking at @Andrey1984’s comments.

Note that a Nano cannot emulate a device in isochronous mode. Isochronous mode is the mode where bandwidth is close to real time, and is typically used for streaming of data. Audio and video is best in isochronous mode.

You can create a camera emulation in bulk mode, but bulk mode isn’t the best of choices.

Sorry I wasn’t clear. Android is not running on the Jetson. These apps are running on an odroid N2 board and I want the Jetson to act as a USB video device to the Odroid board.

For now, as a workaround, I’m outputting to HDMI and using an HDMI to USB video capture device converter which shows up to the Odroid board like a camera. I was just looking to see if there was a way to do it directly from the Jetson without going through this intermediary device.

Yes, that I understand. I am just saying to run those apps on the Jetson itself is not an option. Getting data from the Jetson to the odroid N2 seems to be the only option. The trick is that other than streaming and adapting the stream I don’t think the Jetson would do well emulating a camera. It could be done, but you’d have to use bulk transfer mode and the results might not be all that good.
