Hi and good day,

We have a previous version of Licode installed on our AWS server. The  
video/audio was working fine before we upgraded to the new licode version.  
Right now when we open the basic example, the owner’s video is fine but the  
other video stream shows only black. All the settings we applied on the old  
licode config was also applied on the new one including the aws’ keys.

By the way, if we run this on our local server it runs without any problems.

I hope you can help find the problem

Thank you very much.

Hi and good day,

We have a previous version of Licode installed on our AWS server. The video/audio was working fine before we upgraded to the new licode version.  
Right now when we open the basic example, the owner’s video is fine but the other video stream shows only black. All the settings we applied on the old licode config was also applied on the new one including the aws’ keys.

By the way, if we run this on our local server it runs without any problems.

I hope you can help find the problem

Thank you very much.

I have resolved the issue. Actually after installing turn server I had just  
to fill in  
config.erizoController.turnServer.url = ‘’;  
config.erizoController.turnServer.username = ‘’;  
config.erizoController.turnServer.password = ‘’;  
in licode’s config and it worked. No more black screens. Works fine.четверг, 9 января 2014 г., 16:08:42 UTC+4 пользователь aidgab написал:
