录制30fps的视频可以使用OpenCV库来实现。下面是一个示例代码:
```python
import cv2
# 设置输出视频的帧率和分辨率
fps = 30
width = 640
height = 480
# 创建视频写入对象
video_writer = cv2.VideoWriter("output.mp4", cv2.VideoWriter_fourcc(*"mp4v"), fps, (width, height))
# 打开摄像头
cap = cv2.VideoCapture(0)
while True:
# 读取摄像头帧
ret, frame = cap.read()
if not ret:
break
# 调整帧大小
frame = cv2.resize(frame, (width, height))
# 写入帧到视频文件
video_writer.write(frame)
# 显示录制的视频
cv2.imshow("Recording", frame)
# 按下 'q' 键停止录制
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# 释放对象
cap.release()
video_writer.release()
cv2.destroyAllWindows()
```
这段代码使用`cv2.VideoWriter`来创建一个视频写入对象,并使用`cv2.VideoCapture`打开摄像头。然后,循环读取摄像头帧,将帧写入视频文件中。最后,按下 'q' 键停止录制,释放对象并关闭窗口。你可以根据需要修改帧率、分辨率和输出文件名。<em>1</em><em>2</em><em>3</em>
