Demo: http://labs.eyevinn.se/multiview/?config=example.json

Some limitations apply:

• No support for DRM protected content as this is often solutions specific to each site
• Only tested in Chrome and Safari

Installation

Get the code from Github or fork the repository if you plan to contribute to this project.

git clone https://github.com/Eyevinn/ott-multiview.git

Install the necessary node modules:

npm install

Start the Node express app:

npm start

ENV vars

To start a listener on a port other than 3000, set/export the PORT ENV var. To start a HTTPs server, export:

SSL_KEY=/path/to/key
SSL_CRT=/path/to/cert
SSL_CA=/path/to/CA/cert

If you wish to auto redirect from HTTP (TCP 80) to HTTPs, set/export:

REDIRECT_HTTP=true

Note that you can only start a listener on TCP 80 and 443 as a super user since these are well known port.

Usage

When the Node express app is up and running you can direct your Chrome browser to:

http://localhost:3000/?config=example.json`

where example.json is a configuration file placed in the directory config/ and can look like this:

{
	"row0": [
		{ "title": "View port title",
		  "manifest": "http://example.com/master.m3u8",
		  "type": "hls" }
	],
	"row1": [
		{ "title": "View port title 2",
		  "manifest": "http://example.com/manifest.mpd",
		  "type": "dash" }
	]
}

If a row doesn't have 4 sources, you may opt to add a placeholder video to be displayed. For example, adding:

  "placeholder": [
    { "title": "NO SIGNAL",
      "manifest": "path/to/placeholder/videostream.mpd",
      "type": "dash"
    }
 ]

Will play path/to/placeholder/videostream.mpd in the extra divs. If no placeholder is defined, these divs' display attribute will be set to none, effectively hiding them.

To toggle audio on or off click on the viewport that you want to listen to. A green border indicates for which viewport the audio is enabled. You can also use the keyboard keys 1-8.

Keyboard Shortcuts

• SPACE - toggle play / pause for all viewports
• 1-8 - activate audio for viewport 1 to 8
• F - toggle fullscreen mode
