EVC里怎么用directshow啊？谁有详细的步骤啊！ [复制链接]

求EVC里用directshow的例子！最好是源代码，只要用到directshow就行拉！
谢谢各位大侠啊

在X:\WINCE500\PUBLIC\DIRECTX\SDK\SAMPLES\DSHOW的目录中就有CE5自带的例子的源代码，你可以仔细去研究.

我只做過vs2005 wm5.0的
樓主得把問題說詳細點

最简单的调用directshow播放视频的例子

楼上的大侠有没有EVC下的源码啊。谢谢

ubeczigbee

EVC的沒有
VS2005的倒是做過
可以先安裝個dxsdk看看裡面的代碼

absq

directshow难啊！哎！谁有evc的代码拿出来分享啊。
谢谢呀

所谓的evc和vc，只是编译器不同而已，相同的源代码都可以进行编译，只需要修改些细节而已，唯一不同的是前者生成嵌入式程序，后者是桌面程序。

楼上的大侠说的好啊，但是vc里面有好多东西evc是不支持的啊。

鹏行天下

evc 《 vc，这是必然的，嵌入试程序追求的是高效，节省资源，但对于大多数vc下的api，evc的库都是支持的，可以放心的使用，这点微软考虑的很周到，绝对能满足大多数的需求。
