default pose model crashing

[ilonadem]

Description

Hi, I am trying to run pose_camera.py with a USB camera and it is crashing at variable times (sometimes it takes 10 minutes and sometimes it takes 10seconds). The only thing I've changed are the frame rate and the resolution (because of the camera specs), but I don't know how to fix this issue because the whole camera display shuts down and I am taken back to the login screen again.

Hi, have you tried with any other frame rate and the resolution? Can you please share the frame rate and resolution you are using and the output of below command. Thanks!

v4l2-ctl --list-formats-ext --device /dev/video1

Running the command gives:

and this is how I've implemented it in the file:

def main():
    n = 0
    sum_process_time = 0
    sum_inference_time = 0
    ctr = 0
    fps_counter = avg_fps_counter(30)

    def run_inference(engine, input_tensor):
        return engine.run_inference(input_tensor)

    def render_overlay(engine, output, src_size, inference_box):
        nonlocal n, sum_process_time, sum_inference_time, fps_counter

        svg_canvas = svgwrite.Drawing('', size=src_size)
        start_time = time.monotonic()
        outputs, inference_time = engine.ParseOutput()
        end_time = time.monotonic()
        n += 1
        sum_process_time += 1000 * (end_time - start_time)
        sum_inference_time += inference_time * 1000

        avg_inference_time = sum_inference_time / n
        text_line = 'PoseNet: %.1fms (%.2f fps) TrueFPS: %.2f Nposes %d' % (
            avg_inference_time, 1000 / avg_inference_time, next(fps_counter), len(outputs)
        )

        shadow_text(svg_canvas, 10, 20, text_line)
        for pose in outputs:
            draw_pose(svg_canvas, pose, src_size, inference_box)
        return (svg_canvas.tostring(), False)

    run(run_inference, render_overlay)

if __name__ == '__main__':
    main()

The only thing I've changed are the frame rate and the resolution (because of the camera specs)

Can you please share the frame rate and the resolution you are using. Thanks!

[ilonadem]

Using a frame rate of 30 and resolution of 640 x 480

Seems to be you are using the default values. It should be working fine, not sure why it is not working for you. Have you tried examples-camera repo examples and are you experiencing the same behavior?
