我有一个程序来捕获和保存实时网络摄像头视频。这取自 Expression Encoder 4 附带的示例程序。
LiveJob job = new LiveJob();
EncoderDevice video = EncoderDevices.FindDevices(EncoderDeviceType.Video).Count > 0 ? EncoderDevices.FindDevices(EncoderDeviceType.Video)[0] : null;
EncoderDevice audio = EncoderDevices.FindDevices(EncoderDeviceType.Audio).Count > 0 ? EncoderDevices.FindDevices(EncoderDeviceType.Audio)[0] : null;
LiveDeviceSource deviceSource = job.AddDeviceSource(video, audio);
job.ActivateSource(deviceSource);
//When the Start Encoding Button is clicked.
fileOut.OutputFileName = "C:\\output\\Capture\\Video1.wmv";
job.PublishFormats.Add(fileOut);
job.StartEncoding();
//When the Stop Encoding Button is clicked.
job.StartEncoding();
如何指定编码视频的比特率。
