Today I’ll step back a couple of posts, and add 2 simple lines to allow me to save a video file from the Drone camera. This is a request, and it’s makes a lot of sense to have recorded a file with the drone camera.
The video will later contains detected objects and more, so let’s go with the code. All the magic happens here:
- Lines 97-103. Open the drone camera stream, and also opens a video output stream to save the video file.
- Lines 123-124. Display the camera feed and add the camera frame into the output video file.
- Lines 136-139. Dispose objects, and close the video output file.
