Expression Encoder 4 SDK - 控制DVCAM

问题描述

我正在.NET Framework 4.0中开发一个Windows窗体应用程序，它使用Expression Encoder 4 SDK控制DV-CAM。在过去，我使用了Windows Media Encoder，但是我想升级到Expression Encoder，因为它看起来好多了
可靠。

I am developing a Windows Forms application in .NET Framework 4.0 which controls a DV-CAM using the Expression Encoder 4 SDK. In the past I used Windows Media Encoder for this, but I would like to upgrade to Expression Encoder, because it seems a lot more solid.

总的来说，SDK正在运行很棒，我可以使用LiveDeviceSource和LiveJob控制和查看DV-CAM视频。但似乎缺少一些功能（或者我找不到它们）。我使用以下代码设置与DV-CAM的连接：

Overall, the SDK is working great, I can control and view the DV-CAM video using a LiveDeviceSource and LiveJob. But it seems a few features are missing (or I just can't find them). I use the following code to setup the connection with the DV-CAM:

HandleRef handleRef = new HandleRef(videoPanel, videoPanel.Handle);
_preview = new PreviewWindow(handleRef);
_job = new LiveJob();

Collection<EncoderDevice> devices = EncoderDevices.FindDevices(EncoderDeviceType.Video);
if (devices.Count > 0)
  _device = devices[0];

if (_device != null)
{
  _source = _job.AddDeviceSource(_device, _device); // init a LiveDeviceSource
  _source.PreviewWindow = _preview;
  _job.ActivateSource(_source);
}
