[Fiware-robotics] Kurento KAS + webpages

[Colombatto Davide]

Hi Iñigo,

when I did my test I used the KAS implemented in NodeJS (kurento-one2many-call of the tutorials) with little modifications (i.e. some of these modifications are that you advised to Luis).
I attach my configuration in the email and you can find the KAS code at https://jolnas.myqnapcloud.com/owncloud/public.php?service=files&t=af75683e9342a003c73db4bc9d904592 (password is "robotics"): to use it you have to change in the server.js the ws_uri with your KMS_public_ip (FIWARE-Lab has deleted that I used).

HTML web-pages
KAS also works as "Host-Server" which exposes the web-pages required for the WebRTC Clients (e.g. Google Chrome browsers):

·         Kurento-master (which will send the video) uses the web-page index.html (accessible at "http://KAS_public_ip:port")

·         Kurento-viewers (which will see the video) use the web-page viewer.html (accessible at "http://KAS_public_ip:port/viewer.html)
N.B. these web-pages are simply created splitting the originally unique page (index.html) of the tutorial (kurento-one2many-call) in order to have two different web-pages: one for the Kurento-master and the other for the Kurento-viewers.

Robot side -Master
A .sh ROS node is used to start the WebRTC Client for the Kurento-master (Google Chrome browser) to the web-page index.html:
google-chrome "http://KAS_public_ip:port" --use-fake-ui-for-media-stream

PC side - Viewers
As said above, the viewers can view the video with a Google Chrome browser at the http://KAS_public_ip:port/viewer.html

Robustness issues

1.       Using this solution I see that sometimes (e.g. when you start many Kurento-viewers or you wrongly try to start more than one Kurento-master) the KAS crashes

2.       On my Windows7-PCs work only the solution that use Firefox browsers (working as Master or Viewer)
