Help with Expression Encoder SDK

Question

I am currently experimenting with the Expression Encoder SDK, but I find it very confusing to use when it comes to live streaming. I am trying to capture a video stream from a webcam, encode with my program and then publish it as a live stream from my computer while also injecting script commands. I've been looking through the SDK but I can't find anything pertaining to live streams or webcams. A few code examples mention how to use the Job class to encode, but all I've found is about encoding files locally.

Havent tried it yet but there is a class called Microsoft.Expression.Encoder.Live.LiveJob that is supposed to support streamning. I tried the sample and it streamed a file from my harddisk. I guess it should support encoding video streams too. Here is the sample code (for Encoder 3.0)

using (LiveJob job = new LiveJob())
            {
                // Create a new file source from the file name we were passed in
                LiveFileSource fileSource = job.AddFileSource(fileToEncode);

                // Set this source to Loop when finished
                fileSource.PlaybackMode = FileSourcePlaybackMode.Loop;

                // Make this source the active one
                job.ActivateSource(fileSource);

                // Create a new windows media broadcast output format so we
                // can broadcast this encoding on the current machine.
                // We are going to use the default audio and video profiles
                // that are created on this output format.
                WindowsMediaBroadcastOutputFormat outputFormat = new WindowsMediaBroadcastOutputFormat();

                // Let's broadcast on the local machine on port 8080
                outputFormat.BroadcastPort = 8080;

                // Set the output format on the job
                job.OutputFormat = outputFormat;

                // Start encoding
                Console.Out.Write("Press 'x' to stop encoding...");
                job.StartEncoding();

                // Let's listen for a keypress to know when to stop encoding
                while (Console.ReadKey(true).Key != ConsoleKey.X)
                {
                    // We are waiting for the 'x' key
                }

                // Stop our encoding
                Console.Out.WriteLine("Encoding stopped.");
                job.StopEncoding();
            }
