MCM fails to detect and configure video device exported by FLIR Boson camera connected over USB on a NXP IMX8MP system (/dev/video2).

Verified that streaming works with:

 /usr/bin/rtsp_examples/test-launch "v4l2src device=/dev/video3 ! video/x-raw, width=640, height=512, framerate=30/1 ! queue ! vpuenc_hevc ! rtph265pay name=pay0 pt=96" --port 8555

mcm console output:

Hi @justas-, this is a limitation on the v4l2 crate that we are using, specifically, it is failing at this line.

I don't have the same board or camera, so if you know Rust, here is a minimal reproducible example we can test and submit to them meanwhile:

cargo new v4l2_not_working && cd v4l2_not_working

Then edit the following files:

Cargo.toml:

[package]
name = "v4l2_not_working"

[dependencies]
v4l = "0.14.0"

src/main.rs:

use v4l::video::Capture;

fn main() {
    let device = v4l::Device::with_path("/dev/video3").unwrap();
    dbg!(&device);

    let caps = device.query_caps().unwrap();
    dbg!(&caps);

    let formats = device.format().unwrap();
    dbg!(&formats);
}

Apart from that, we also have the idea of switching from interfacing with v4l directly, to using GST Device Monitor to get all this information.

Thanks
