Re: watch live video through hdmi using USB cam

I must have misread something. You have monitor hooked up to hdmi connector of your Pi, you have desktop running on your Pi so you are looking at a monitor hooked up directly to your Pi

Re: watch live video through hdmi using USB cam

1. Install Raspbian and make sure you have a working desktop
2. Install mjpeg-streamer (https://wolfpaulus.com/journal/embedded ... pi_webcam/)
3. Launch browser on your desktop and open http://localhost:8080

You should get full resolution at full frame rate of your usb cam

Re: host camera module mjpeg output on remote server?

If you re-phrase your question to "live video streaming on your website" or "embed live video in your webpage" you will get a lot more leads. Essentially you need to subscribe to a video broadcasting service (like ipcamlive.com) then make your Pi feed a video stream to that service then embed requir...

Re: Fuel flow + temp sensor development project

Industrial type fuel flow and temp sensor usually have 4-20mA output. Search for 4-20mA raspberry pi / arduino and you should be able to find solutions or circuit boards (shield) already made. Essentially for each sensor you would need an external power supply and an 250 Ohms precision resistor to c...

Can somebody advise me on how to constantly record video without interruption?

You have a dropped frames problem. Create an XFS partition on your SD and save your clips there.

Follow the instructions and make it work first. Then make following modification: install nginx+rtmp module on your server (instead of on your Pi) and have ffmpeg running on your Pi feed video stream to it.

Re: Multiple cameras on a single raspberry pi board

I have connected and used 3 logitech webcams via a powered USB hub. Since the output of the webcams are already in MJPEG format, the RPi CPU does not have to do any encoding and the CPU load is low. Since you just need to take snapshots, the bandwidth required across the USB port will also be low an...
