yolo检测后视频文件如何直接转流

Question

im0 = annotator.result()
            if view_img:
                if platform.system() == "Linux" and p not in windows:
                    windows.append(p)
                    cv2.namedWindow(str(p), cv2.WINDOW_NORMAL | cv2.WINDOW_KEEPRATIO)  # allow window resize (Linux)
                    cv2.resizeWindow(str(p), im0.shape[1], im0.shape[0])
                cv2.imshow(str(p), im0)
                if cv2.waitKey(1) == ord("q"):  # 1 millisecond
                    exit()

            # Save results (image with detections)
            if save_img:
                if dataset.mode == "image":
                    cv2.imwrite(save_path, im0)
                else:  # 'video' or 'stream'
                    frame_count += 1  # Increment frame count

                    # Check if we need to start a new video
                    if frame_count % 300 == 0:
                        chunk_number += 1
                        if isinstance(vid_writer[i], cv2.VideoWriter):
                            vid_writer[i].release()  # release previous video writer
                        save_path = str(Path(save_dir) / f"chunk_{chunk_number}.mp4")
                        fps, w, h = 30, im0.shape[1], im0.shape[0]
                        vid_writer[i] = cv2.VideoWriter(save_path, cv2.VideoWriter_fourcc(*"mp4v"), fps, (w, h))

                    if isinstance(vid_writer[i], cv2.VideoWriter):
                        vid_writer[i].write(im0)
                        if rtsp_writer is None:
                            rtsp_writer = cv2.VideoWriter(rtsp_url, cv2.VideoWriter_fourcc(*"H264"), 20,
                                                          (im0.shape[1], im0.shape[0]))
                        rtsp_writer.write(im0)

有人知道如何解决yolo检测输出的是一个不可读取的MP4文件 可以直接转成流
