Render to video stream - Glium

help
1

Hi,

I need to create a video stream using frames rendered by Glium (like a video device in /dev) that can be used by other applications or output through say HDMI.
As of now my program renders to a Glutin window like in the example code in the tutorial:

fn main() {
    use glium::{glutin, Surface};

    let event_loop = glutin::event_loop::EventLoop::new();
    let wb = glutin::window::WindowBuilder::new();
    let cb = glutin::ContextBuilder::new();
    let display = glium::Display::new(wb, cb, &event_loop).unwrap();

    event_loop.run(move |ev, _, control_flow| {

        let mut target = display.draw();
        target.clear_color(0.0, 0.0, 1.0, 1.0);
        target.finish().unwrap();

        let next_frame_time = std::time::Instant::now() +
            std::time::Duration::from_nanos(16_666_667);

        *control_flow = glutin::event_loop::ControlFlow::WaitUntil(next_frame_time);
        match ev {
            glutin::event::Event::WindowEvent { event, .. } => match event {
                glutin::event::WindowEvent::CloseRequested => {
                    *control_flow = glutin::event_loop::ControlFlow::Exit;
                    return;
                },
                _ => return,
            },
            _ => (),
        }
    });
}

How do I render to a video stream target instead? Thanks.
