192.168.1.128 IP of your computer

Configuration

PulseAudio

Play webcam using mplayer

To play webcam using mplayer, we will need to use TV input but with v4l2 as driver,

  $ mplayer tv:// -tv driver=v4l2

then it just plays with default values. We can add options to tweak such as width, height, output format, frame rate, select device…Each option is separated by a colon. For example, play webcam from /dev/video0, with widthxheight=1280×720, framerate=30, and output format is YUV (YUY2),

	Okay so here's the setup:

	[-] The primary server API is exposed via Flask (Python) and all static files, including all html, css, js is served by nginx.
	[-] Python is exposing an API at url http://domain.com/api/download/<file_id>, where file_id is a database id for the file that we're interested in downloading.

	1. User wants to download a file, so we spawn a new window with the url '/api/download/<file_id>'
	2. Nginx intercepts the request, sees that it starts with /api/, and then forwards the request to Flask, which is being served on port 5000.
	3. Flask routes the request to its download method, retrieves the pertinent data from the file_id, and constructs additional header settings to make nginx happy and to force the browser to see the file stream as a download request instead of the browser just trying to open the file in a new window. Flask then returns the modified header stream to nginx
	4. Nginx is finally ready to do some work. While parsing the headers for the incoming request, it encounters "X
