+#### Lock video orientation
+
+
+To lock the orientation of the mirroring:
+
+```bash
+scrcpy --lock-video-orientation 0   # natural orientation
+scrcpy --lock-video-orientation 1   # 90° counterclockwise
+scrcpy --lock-video-orientation 2   # 180°
+scrcpy --lock-video-orientation 3   # 90° clockwise
+```
+
+This affects recording orientation.

 ### Recording
 
 It is possible to record the screen while mirroring:
