Usage: Usage: wmvcopy -i <INPUT_FILE> -o <OUTPUT_FILE> [-f <FROM>] -d <TIME> [-s] -i <INPUT_FILE> = Input Windows Media file name -o <OUTPUT_FILE> = Output Windows Media file name -f <FROM> = from which position to copy, in seconds of the input file, if omitted, copy from the head -d <TIME> = specify the max duration in seconds of the output file, -s = Move scripts in script stream to header ----------------------------------------------------------- ================================================================================ 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.
