顶一下，最近在搞UDP协议的传输，用的
[DllImport("MSVFW32.dll"),PreserveSig]
public static extern int ICOpen(int fccType,int fccHandler,ICMODE wMode);
没搞出来，获取视频流的时候不行
[DllImport("MSVFW32.dll"),PreserveSig]
public static extern int ICOpen(int fccType,int fccHandler,ICMODE wMode);

LZ解决了吗？ 我也在寻找这个如何获取视频流的问题。
#5
我也找，顶一个，说话我获取了，但不知道怎么保存成AVI文件，VC++。
