Dogfooding the Presentation API

Dominik, Anssi, Louay and I have been working on a series of demos to experiment with the Presentation API and hopefully iron out edge cases in the API early on.

Demos that have been assembled so far:

  • The initial video sharing demo that lets one present a video on a second screen using an HTML video player.
  • The <video> sharing demo that investigates using the HTMLMediaElement interface to control a video presented on a second screen.
  • The HTML Slidy remote demo that takes the URL of a slide show made with HTML Slidy and presents it on a second screen, turning the first screen into a slide show remote.
  • The Fraunhofer FOKUS’ Competence Center Future Applications and Media (FAME) has also been working on a number of implementations of the Presentation API as part of FAMIUM, an end-to-end prototype implementation for early technology evaluation and interoperability testing introduced by FAME.

Different types of second screens are supported depending on the demo considered, using custom version of Web browsers, browser extensions, etc. All demos fallback to opening the content in a separate browser window.

We will try to keep these demos aligned with the evolutions of the Presentation API, and complete the Presentation API demos page with additional ones over time. Feel free to share demos or suggestions on the group’s mailing-list!

Second Screen Video Sharing Use Case Demo Released

Intel’s OTC has released code and binaries for the video sharing use case demo online on the webscreens github project:

(edit 16.6.2014, URL updated) http://webscreens.github.io/demo/

This demonstration provides an example of the video sharing use case that is listed as one of the important use cases for Presentation API.  It is similar to the demo that was shown during the the W3C TPAC Session.

Using the binaries from the page, or building your own version of Chromium with the provided patches applied, you can get an impression of what using Presentation API might look like and the sort of new usage scenarios that it enables. It’s also possible to experiment and build your own examples.

More details can be found on the demo page.
