如何让DirectShow播放资源中的视频? [英] How do you get DirectShow to play a video from a resource?

问题描述

我正在扩展一个应用程序，以在对话框中的控件上播放多个视频之一.从无窗口示例开始，尽管视频必须是与主要可执行文件分开的文件，但我已经可以正常工作了.

I'm extending an application to play one of several videos on a control in a dialog. Starting with the Windowless sample, I've got this working, though the videos have to be separate files from the main executable.

从打包的角度来看，理想的方案是将视频作为资源包含在可执行文件中.我为此做了一些谷歌搜索，并且有相当多的有人应该这样做"，还有一些指向异步示例的指针，尽管尚不清楚如何从那里到达我想要的位置.

The ideal scenario from a packaging standpoint is for the videos to be included with the executable as resources. I did a bit of googling for this, and there's a fair amount of "somebody should do this", and several pointers to the Async sample, though it's not clear how to get where I want from there.

有人知道这样做的简单方法吗?似乎这不是一个死角子，我对此并不感到惊讶.

Does anybody know a simple way to do this? It doesn't seem like this is a corner case, and I'm a bit surprised that this wasn't in the box.

Look for Async Filter Sample in the DirectShow SDK, It has impl something called CMemStream which can stream data (read: media) from memory. more info on this blog post
