Hi, when I click on the start recording button in the example, I get the  
following error from Erizo:

/home/marko/licode/erizo\_controller/erizoController/erizoController.js:532  
if (socket.room.streams[streamId].hasAudio() ||  
socket.room.stream  
^

No erizoController is available.

Additionally, I have noticed that localStream.getID() returns undefined…  
does anybody have an idea what I might be doing wrong?

Hi, Marko.
