How do I create a live video stream with a Raspberry Pi and a Java tomcat server?

Question

I'm trying to live stream video from a Raspberry Pi to webpages of the connected clients, for example: the server will be hosted in one location "A" and the Raspberry Pi is connected to this server. If a user accesses the web application from location "B" using the URL, and wants to view the live video, how can I achieve this?

As per my understanding I have to stream content from Raspberry Pi webcam to a Tomcat server. Please suggest to me how can I achieve this. Please do suggest me some examples as well.

Answer 1

uv4l is pretty good for streaming with very little lag

http://www.linux-projects.org/uv4l/

$ curl http://www.linux-projects.org/listing/uv4l_repo/lrkey.asc | sudo apt-key add -

then add the source to your source list sudo vim /etc/apt/sources.list

$ source="deb http://www.linux-projects.org/listing/uv4l_repo/raspbian/ jessie main" 
$ echo $source | sudo tee -a /etc/apt/sources.list

then update, and get the packages you need

$ sudo apt-get update
$ sudo apt-get install uv4l uv4l-raspicam uv4l-raspicam-extras uv4l-server uv4l-webrtc

update your firmware

$ sudo rpi-update

the run the server

$ uv4l --driver raspicam --auto-video_nr --width 640 --height 480 --encoding h264

go to http://raspberrypi:8080/stream in a browser on the network to view the stream (where raspberrypi is your pi's ip or hostname)

$ sudo pkill uv4l

to stop it

Answer 2

I would start with this stream m you can set it up on your server. Then on raspberry pi you could use ffmpeg to stream h264 or webm video from your raspberry camera.
