Requirements

Python3, numpy and cv2 are required to run this script.

Install OpenCV 3.1 for Python3, and then install other requirements:

pip install -r requirements.txt

Configure

Edit mjpg stream source url here:

capture = cv2.VideoCapture("http://pi-frc-9036.local:5801/stream.mjpg")  # Maybe http://localhost:8080/?action=stream

Edit output video parameters here:

out = cv2.VideoWriter(filename, fourcc, 24.0, (640, 480)) # filename, output type, fps, frame size

If you want to capture camera image at low exposure, install v4l2 and run these commands in bash (this can only apply to Microsoft LifeCam 3000):

v4l2-ctl -c exposure_auto=1 && v4l2-ctl -c exposure_absolute=5

Run

To capture a video:

./capture.py --name test.mp4        (Linux)
python capture.py --name test.mp4   (Windows)

It may take about 20 seconds to connect to your video stream.

To extract a video:

mkdir result

./extract.py --name test.mp4        (Linux)
python extract.py --name test.mp4   (Windows)

Then each frame will be extracted to result/field.test.mp4.xxx.jpg.
