HELP to use a cam with MM PLEASE

@axel
If your webcam has IP or URL address to stream video output, MMM-RTSP… or some iFrame modules could work.

see my usb cam in live on the mirror!

If you can get an RTSP stream URL from your IP camera you can use my module: MMM-RTSPStream. Use the develop branch right now–and search this forum if you’re having issues getting it to work.

If you want to stream your USB camera by hooking it up to the Pi, you can look at something like mjpg-streamer (Google ‘OctoPrint mjpg-streamer setup’ for some good guides) and then use MMM-iframe to show the image.

$ mjpg_streamer -o “output_http.so -w ./www” -i “input_uvc.so -f 1 -q 75 -y”

The default port is the same as the Mirror, 8080. Try adding -p 8081 to your command to change the port.

it works well but now i tried To start mjpg on boot in vain. I used the crontab but how To write it with the options??

@axel - Create a script with your command, name it something obvious like startcam.sh. Make it executable with chmod +x startcam.sh and then use pm2 to autostart and maintain the script: pm2 start startcam.sh When you’re satisfied with pm2’s handling, save the state: pm2 save

In the future, please use the markdown features of the board when posting code & logs.

i did it but the status is not online but stopped. After a moment, the status changed To errored!! Help please…

[bhepler]

@axel - Okay. Let’s skip PM2 for now and just concentrate on getting your script running.

Edit the startcam.sh script and paste in the mjpg_streamer command:
mjpg_streamer -o “output_http.so -w ./www” -i “input_uvc.so -f 1 -q 75 -y” -p 8081

Once you have the script file to where it’s only that command, you can try to run that script manually by typing ./startcam.sh. That should be the equivalent of typing the command in yourself.

Try that and let us know how it goes.

@bhepler
Ok i can run manually the script.
and now?

@axel he said

you can try to run that script manually by typing ./startcam.sh.

he left off that you need to mark the script as executable

chmod +x ./startcam.sh

[axel]

@sdetweil
i did it before 😉

[bhepler]

@axel - Now that you can run your script and have it execute the command (I’m assuming that when you run the script, it does what you want) you just have to tell pm2 to manage that script.

Tell pm2 to manage the script: pm2 start startcam.sh
Tell pm2 to remember & autostart the script: pm2 save

Let us know how it goes.
