Data usage with video disabled

[deyupopp]

Hello, While investigating the GoCoder SDK for a feasibility test for our application, we used the following video stream:

{
                HostAddress = "wowzaec2demo.streamlock.net",
                ApplicationName = "vod",
                StreamName = "mp4:bigbuckbunny_450.mp4"
} 

We did some profiling and noticed that the data usage is the same, regardless of using videoEnabled true or false. Do you know if this is expected, or does it have something to do with the file format or the protocol?

Thank you, Andrei
