有关在C＃中设置FIle Writer的问题 [英] Question about setting up FIle Writer in C#

问题描述

我在C＃中使用DirectShowLib。我想在C＃中使用File Writer来设置文件输出。我想使用File Writer，因为Graph.SetOutputFileName（）不会连接到我的编码器，但是File Writer可以。我该如何在C＃中设置文件编写器保存的文件？

Im using DirectShowLib in C#. I want to use File Writer in C# to set a file output. I want to use File Writer because Graph.SetOutputFileName() wont connect to my encoder, but File Writer will. How can i set the File that File Writer saves to in C#?

我尝试像DxPropPages示例中那样拉起其属性页，但文件不会出现

I tried pulling up its property pages like in the DxPropPages example but one won't come up for File Writer.

我知道如何在代码中将文件编写器添加到我的
图中，我只是不知道如何
设置文件路径

"I know how to add file writer to my graph in code i just dont know how to set the file path"

尝试以下操作：

FileWriter fileWriter = new FileWriter();
IFileSinkFilter fileSinkFilter = (IFileSinkFilter)fileWriter;
fileSinkFilter.SetFileName(fileOutput, null);
