For People In A Hurry: How To Set Up mjpg-streamer

README.md

Note

This is a quick copy-paste-observe guide that shows you how to set up and run a mjpg-streamer. This allows you to easily have a web camera video stream available within a LAN.

Instruction(s) 📘

1. Download mpjg-streamer:

git clone https://github.com/jacksonliam/mjpg-streamer --branch v1.0.0 --single-branch --depth 1 && cd mjpg-streamer

2. Build using the commands below:

cd mjpg-streamer-experimental && make && sudo make install

3. Plug in your USB web camera physically into your edge device.

4. Determine the available resolution using the command below:

v4l2-ctl --list-formats-ext

Note

You should see a terminal output similar to what is shown below:

ioctl: VIDIOC_ENUM_FMT

Type: Video Capture

		Interval: Discrete 0.200s (5.000 fps)
  ...

5. Run mjpg_streamer:

#Eg.
./mjpg_streamer \
    -i "./input_uvc.so -d /dev/<DEVICE_MOUNT> -r <FRAME_WIDTH>x<FRAME_HEIGHT> -f <FPS>" \
    -o "./output_http.so -w ./www -p <PORT_NO>"

• DEVICE_MOUNT refers to /dev/video mount point.
• FRAME_WIDTH refers to the integer on the left hand side.
• FRAME_HEIGHT refers to the integer on the right hand side.
• FPS refers to the fps value.
• PORT_NO refers to the port the user intends to expose the video stream on.

#Eg.
./mjpg_streamer \
    -i "./input_uvc.so -d /dev/video0 -r 1280x720 -f 30" \
    -o "./output_http.so -w ./www -p 8080"

6. Access the video stream via the link below:

http://<IP_ADDRESS>:8080/?action=stream

IP_ADDRESS refers to the IP address of the edge device in question.

Tip

Run

export WIFI_IP=$(hostname -I | awk '{print $1}')
echo $WIFI_IP

http://localhost:8080/?action=stream
