多条Graph可以实现,但是控制起来特别麻烦. 因为我要在一个显示窗口正常被控制的条件下,对第二个显示窗口进行特殊操作,并且两个窗口要进行显示对比.现在,一个窗口下的所有操作基本完事.
今天找帮助,看到\Samples\Multimedia\DirectShow\Filters\InfTee下有个InfTee Filter Sample实例.但是运行的时候出现"please specify the name of the executable file to be used in this debug session". 的提示.头晕~~~ 于是,在网上找到了有解答的,但是按照解答的说明还是没有结果啊~ 头晕!~ 那个解答如下:
If you build the demos, it should build executables for them.
But the error message you're getting is simply because you probably pressed F5 (or Ctrl-F5) and hadn't selected a runnable project as your "Startup Project" from the list of projects in the bution file. Simply right-click on one of the demos (demo_moving_trimesh for example) and select "Set as Startup project"from the pop-up menu, then press F5 and it should run.
The Startup Project is the one in bold. If it's a library (like the ode project) then you'll get the message you got. When you first open the project files it gets set to whatever it wants to, so it's very possible it was set to a lib and you have to set it to an actual runnable (executable) project.
Alternatively, if you just wanted to build ODE, press F7 (or Ctrl-Shift-B, for
Build Solution) instead of F5 which is Run (Debug).
看了一下上面那个实例,感觉是在演示这个filter内部在实现多个output pin的具体实现.请问是否有函数直接调用即可实现多个output pin 操作???????

要分别控制，还是多条Graph吧

微软提供了两个Tee Filter：Smart Tee和Infinite Pin Tee Filter。前者有两个Output pin,且Preview pin输出的Sample已经去掉时间戳；后者，可以动态产生无数个Output pin，而且各个Output pin输出的Sample是完全一样的。
谁能提供个VC的实例啊?谢谢~
