 +===== Identify VIM4 Version =====
  
-===== Record Video via Gstreamer =====+<WRAP important >
  
 +There are two versions of **VIM4**, they are **VIM4** and **New VIM4**, as they have different ISP IP core, so the usage of MIPI camera is also different,
 +please follow the documentation to identify your VIM4 version and choose the right documentation for your VIM4.
  
-==== Install Gstreamer Encoder Plugin ==== 
-```shell 
-sudo apt update 
-sudo apt install gstreamer-aml 
-``` 
- 
-==== Record Video ==== 
-```shell 
-gst-launch-1.0 v4l2src device=/dev/video50 io-mode=mmap num-buffers=300 ! amlvenc ! h264parse ! qtmux ! filesink location=test_50.mp4 
-``` 
-/* ===== Demo Source Code ===== 
- 
-This part is some Demo Source Code that will guide you how to use it to test your camera. 
- 
-==== Install OpenCV4 ==== 
- 
-```shell 
-$ sudo apt install libopencv-dev python3-opencv 
-``` 
-==== Python ==== 
- 
-```python mipi-camera.py 
-import cv2  
- 
-if __name__ == '__main__': 
- 
-    val = True 
- 
-    cap = cv2.VideoCapture(0) 
-    cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1920) 
-    cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080) 
- 
-    fourcc = cv2.VideoWriter_fourcc(*'XVID') 
- 
-    out = cv2.VideoWriter("./test.avi", fourcc, 20.0, (640, 480), True) 
- 
-    while val is True: 
-        ret, frame = cap.read() 
-        cv2.cvtColor(frame,cv2.COLOR_RGB2BGR) 
-        if frame is None: 
-            break 
-        else: 
-            out.write(frame) 
-            cv2.imshow("video", frame) 
-            k = cv2.waitKey(1) & 0xFF 
-            if k == 27:  
-                break 
- 
-    cap.release() 
-    out.release() 
-```
