The goal of this project is to create a simple webcam based security system that allows a user to remotely view the devices web cam by navigating to a webpage. Then using buttons the user can change what camera they are viewing.
//Give two sentences telling what works. Currently we have the ability to select a camera and view the stream in a remote webpage. This view uses the VLC Plugin.
Give two sentences telling what isn't working. Currently we do not have the system switching between camera's via user inputs. We have not tested with multiple cameras.
End with a two sentence conclusion. Investigation of how to accomplish this task took up the bulk of our time and effort due to the infancy of HTML5 Related standards(sockets.io and MediaStream). We decided to utilize the vlc plugin when solving the problem with HTML5 proved unfeasible at its current level of development.
Give step by step instructions on how to install your project on the SPEd2 image.
- Include your github path as a link like this: https://github.com/MarkAYoder/gitLearn.
- Include any additional packages installed via opkg.
- Include kernel mods.
- If there is extra hardware needed, include links to where it can be obtained.
Preliminary: host$: node core.js
Here is where you brag about what your project can do.
Include a YouTube demo.
Theory of Operation
Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.
List the major tasks in your project and who did what.
Also list here what doesn't work yet and when you think it will be finished and who is finishing it.
- GStreamer Implementation- John Lobdel investigated using GStreamer to acomplish this project. This implementation in the end proved effective and the easiest to implement.
- Program Creation- John Lobdel used his research to get gstreamer to stream a video or camera input onto port 8081 that could then be read by the VLC Media Player on a remote computer. The further integration of this into a program was done with the introduction of the VLC-plugin in an html document. The final program was jointly compiled by both John and Alex.
The program creation went quite fast after a working method was discovered by John. Then it was a matter of putting the pieces together. The program consists of a node.js client server using the example provided in the examples/node.js folder, which provides the HTML server and controls for which video to stream. We embedded the vlc viewer into the page and pointed it to the location where the video would be streamed by an external function call in the .js file. This allows for a simplified approach to running the needed utilities without having to port code into the java script language.
Add video capture would add true security camera capabilities to this system. In addition adding motion detection into the video selection stream would be interesting. Though this might be too much for the XM's hardware.
Having a webpage that displayed all of the video feeds at once would also be an interesting feature but this could over tax the XM's hardware or internet connection.
Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
