In another post (Live Stream Server Raspberry Pi), I showed how to make a live stream from a Raspberry Pi. This was good for a security system, but not good for if you want to watch this video and show it to others. The video on the other post was 720p and only 2 frames per second. This video will be still MJPEG (Motion JPEG) for better streaming but will be 1920 by 1080 and be up to 30fps.

Make sure you have one of these USB webcams or the stream might not work:
List of compatible webcams

Run these two commands to make sure OS is up to date

sudo apt-get update

sudo apt-get upgrade

Install VLC media player:

sudo apt-get install vlc

Run this command to start the stream:

cvlc --no-audio v4l2:///dev/video0 --v4l2-width 1920 --v4l2-height 1080 --v4l2-chroma h264 

--v4l2-fps 30 --v4l2-hflip 1 --v4l2-vflip 1 --sout '#standard{access=http,mux=ts,dst=:8080}'

-I dummy

Here are instructions to retrieve an image from the stream:

Install ffmpeg (If this doesn't work you will have to build ffmpeg locally):

sudo apt-get install ffmpeg

Download an image (Put in the IP):

ffmpeg -y -i http://Raspberry'sIP:8554/ -r 1 -vframes 1 now.jpg

I wanted to electronically record my inhaler usage, but there was no simple easy to use way to do this, so I created  this app. My goal for this app is to record my inhaler usage and see the trends of when I need my inhaler. This app is available on both the Google Play Store and Apple App Store. I built this app using HTML/CSS and JavaScript and then packaged it for both iOS and Android using Cordova.

Here is a short YouTube Demo of my app:

In this tutorial, we are going to take the Raspberry Pi webcam server project one step further by giving the raspberry pi the capability to send you an email whenever it detects motion. Motion, the software we are using for our security system, already can detect motion and will only record video if it has motion in it. We are sending emails by making an SMTP server with NodeJS. We are using the Nodemailer package to configure the SMTP server. The full-length detailied YouTube tutorial is below.

In this tutorial, I'm going to show you how to make a live stream server with your Raspberry Pi. At the end of this post, there is a YouTube tutorial with detailed instructions on how to set up this server. This tutorial uses a program called Motion. The wiki for Motion is here:
