Can't make the externalinput works

Hi there!
I’m trying to use the externalinput for the first time but I’m encountering some probles.
first of all i opened up basicexample and recorded a video.
Then I tried to publish with these options:
localStream = Erizo.Stream({ video: true, audio: false, recording: “71300404539612616” });

the video is being published to Erizo, but if I try to open another page with ?onlySubscreibe=true, the sdps are exchanged but no video is shown in the page

Am I missing something?

I am sorry, I found the clue. You can delete this post if you want (ps. would be nice to let users delete their own posts)
