WIN32 Console Application : WMVRecompress
|
|
================================================================================
|
|
|
|
This sample shows the necessary code to recompress a WMV file.
|
|
|
|
It shows reading uncompressed samples, writing uncompressed samples, multi-pass
|
|
encoding, multi-channel output, and smart recompression.
|
|
|
|
Usage: WMVRecompress -i <INPUT_FILE> -o <OUTPUT_FILE>
|
|
{ -ps <SYSTEM_PROFILE_INDEX> | -pf <CUSTOM_PROFILE_FILE> }
|
|
[-m] [-c] [-s]
|
|
-i <INPUT_FILE> = input ASF/WMV/WMA file name
|
|
-o <OUTPUT_FILE> = output file name
|
|
-ps <SYSTEM_PROFILE_INDEX> = system profile index
|
|
-pf <CUSTOM_PROFILE_FILE> = custom profile file name
|
|
-m = use multi-pass encoding
|
|
-c = enable multi-channel output for the source file (for Windows XP only)
|
|
-s = enable smart recompression for audio stream
|
|
|
|
To build the sample, open the project file WMVRecompress.sln in Visual Studio and build
