Hi,

We have upgraded our Licode based application with newer commits since  
April 2015 and we have detected an issue with screen sharing recording.  
Before the update we were able to record both camera and screen streams.  
Now when we record screen videos the result mkv files have video and audio  
tracks but there’s nothing in them (and then our post-process fails). We  
have made a clean clone from github in a clean Ubuntu 14.04 LTS and this  
happens there too. The only way to get recorder successfully screen streams  
is calling the method startRecording() just when the event stream-added is  
fired, if you wait for example a 100ms timeout the recording doesn’t work  
well.

Does anybody have the same problem? Hope we can solve this.

Sergio.
