                    WIN32 Console Application : WMVCopy
================================================================================

This sample shows the necessary code to copy a WMV file.

It demonstrates how to read compressed samples, write compressed samples, read 
header attributes and scripts, and modify header attributes.

Usage: wmvcopy  -i <INPUT_FILE> -o <OUTPUT_FILE> -d <TIME> [-s]
  -i <INPUT_FILE> = Input Windows Media file name
  -o <OUTPUT_FILE> = Output Windows Media file name
  -d <TIME> = specify the max duration in seconds of the output file
  -s = Move scripts in script stream to header

  Note: this program will not copy the image stream in the source file.

To build the sample, open the project file WMVCopy.dsp in Visual Studio and build 
the project.
