Expression Encoder 3 Livejob，是否可以在某个时刻开始流式传输文件。

问题描述

是否可以从文件创建一个LiveJob并让它开始在特定点广播，比如文件duraction 3分钟？

Is it possible to create a LiveJob from a file and have it begin broadcasting at a certain point say 3 mintues into the the file duraction?

我粘贴了livejob示例来自编码器sdk。

I pasted the livejob example from the encoder sdk.

例如

LiveFileSource.jumpto（new timespan（0,3,0））; //跳转到源文件三分钟。

LiveFileSource.jumpto(new timespan(0,3,0)); //jumpto three minutes into the source file.

我意识到.jumpto不能以这种方式运行，但是有什么用呢？

I realize the .jumpto does not function in this manner, but is there something that does?

        static void Main(string[] args)
        {
            // We should have only 1 string in the argument array, and
            // it should be the name of the file we are going to encode
            if (args.Length != 1)
            {
                Console.Out.WriteLine("Usage: live <file_name>");

            string fileToEncode = args[0];

            // Create a new LiveJob to begin broadcasting this file. Make sure
            // to dispose the LiveJob when you are finished with it.
            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();
            }
        }
    }
}
