Question

Poor audio latency

Hi,

I've got a FMS server running that is hosting a simple video conferencing application. The problem I'm seeing is that when two computers are sitting next to one another, the audio delay between streams is minimal, perhaps 1s. When computers are farther apart, the audio lag gets much worse, often with a 5s delay. I don't see any actionscript parameters that I can modify that may help get this under control. Are there things I can do on the actionscript side (either on the client or server) that could help improve this situation? How likely is this simply a server problem?

Thanks.

    Hi,

    Are you setting netStream buffer on client side(NetStream.setBufferTime) that might be causing delay. If you are setting it then try decreasing buffer on client side to 0.1 to 0.2 second.

    On FMS, you can try decreasing the Live Buffer/queue size OR disabling the Live Buffer/queue completely, But with a caution as disabling the queue will give very low latency but will affect the server performance.

    Regards,

    Amit

    I'm not using NetStream.setBufferTime on the client, so that shouldn't be an issue.

    What is the API for modifying/disabling "Live Buffer/queue size" on the server?

    Thanks.

    Checkout <MsgQueue> tag in Application.xml under this tag you can have these settings.
