Where can I find the Miracast specification?

Question

I want to develop a Miracast application for Mac OS X. (i.e. something to display imagery to a miracast-enabled device) The only problem I'm having right now is that I can't find the official specification for this.

Is it possible that you need to be a member of the wi-fi alliance to get this specification? Is this even an open standard?

Or better: Is there a (open-source) miracast library I can use?

Thanks!

Answer 1

Have you seen this? http://www.freedesktop.org/wiki/Software/openwfd/

As for the wi-fi alliance, you don't need to be a member but it will cost you $199: https://www.wi-fi.org/wi-fi-display-technical-specification-v11

Answer 2

The Wifi Display spec is currently free (as in 0.0$). The download still requires agreeing to a license agreement and does not seem free to redistribute.

Also, WDS is a new but fairly complete implementation for linux and should be easy to port to other platforms as it tries very hard to keep agnostic with respect to the stacks used to handle media playback and Wi-Fi Direct. That said, the most difficult bit in Miracast seems to be Wi-Fi Direct so if your platform does not support that well, you're pretty much out of luck...
