有什么方法可以通过编程方式控制DirectShow VSFilter吗？ [英] Is there any way to control DirectShow VSFilter programmatically?

问题描述

我正在尝试以编程方式将字幕文件设置为DirectShow VSFilter。
可以通过其属性页来执行此操作，但是我找不到任何有关其API的文档，即使它有一个。

I'm trying to set up a subtitles file to DirectShow VSFilter programmatically. There is a way to do so through its property pages but I can't find any documentation regarding its API or even if it has one.

是否有任何API，互操作性以及可以为VSFilter设置字幕文件的东西？

Is there any sort of API, Interop, anything which would allow to set up a subtitle file for VSFilter?

推荐答案

VSFilter上没有特定的文档，但是它是开源软件。因此，您可以下载源代码，并参考其接口定义，例如在MPC-HC源 \Mpc-hc\src\filters\transform\vsfilter\IDirectVobSub.h 中，并使用该界面以编程方式控制过滤器。

There is no specific documentation on VSFilter, however it's open source software. So you can download source code, reference its interface definition e.g. in MPC-HC source \Mpc-hc\src\filters\transform\vsfilter\IDirectVobSub.h and use the interface to control the filter programmatically.

    interface __declspec(uuid("EBE1FB08-3957-47ca-AF13-5827E5442E56"))
IDirectVobSub : public IUnknown 
    {
        STDMETHOD(get_FileName) (THIS_
                    WCHAR* fn   // fn should point to a buffer allocated to at
                                // least the length of MAX_PATH (=260)
                 ) PURE;

        STDMETHOD(put_FileName) (THIS_
                    WCHAR* fn
                 ) PURE;
// ...
