Displaying video streams in flask

[epigraphe]

Hello. I have a script that, after recognition and detection based on yolo, should output the final video to a web application.
I was able to do this on streamlit, and now I’m trying to transfer it to flask (I still need all the statistics next to these videos)
The problem is that I can’t display the flow display in Flask.

I have code for streamlit that works:

video_placeholders = [st.empty() for _ in range(3)]

for i, result in enumerate(results):
    image = result.orig_img
    detection_results = model(image)[0]
    detections = sv.Detections.from_ultralytics(detection_results)
    detections = tracker.update_with_detections(detections)

    annotated_frame = process_frame(image)
    resized_image = cv2.resize(annotated_frame, (1024, 768))
    video_placeholders[i % 3].image(resized_image, channels="BGR", use_column_width=True, caption=f"Video {i + 1}")

How to convert it for flask?
