Hi all,

I try to get the following java code to work:

public static void main(final String[] args) throws IOException {
    System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    final String filename = "E:/tmp/m.avi";
    final VideoCapture vc = new VideoCapture();
    final boolean result = vc.open(filename);
    System.out.println(result);
}

Unfortuantely, it prints "false", thus it will not open the file.

The system is a Windows 7. I have no additional codecs installed. The file is definitely at this place. I can watch it with Windows Media Player.

You can find the file attached to this bug report as m.avi.

Thanks for your help!

Ok, after some work I got a C++ program to compile (not so easy, if you never build C++ programs :-). I wrote basically the same program in C++. It also prints false. So, it can probably be ruled out that it is a bug in the java wrapper. Still, I have no idea what exactly the problem is. So, I am grateful for every hint.

Can anybody close my quesion, since it is just a duplicate of this one?

My problem has nothing to do with java at all. I asked the author of the linked question for his file julius.avi. I can read this one with java, but no other file.
