WIN32 Console Application : UncompAVIToWMV
================================================================================
This sample shows the necessary code to compress an AVI file to a WMV file.
It shows how to merge samples for audio and video streams from several AVI files
and either merge these into similar streams or create a new stream based on the
source stream profile. It also shows how to create an arbitrary stream, do
multipass encoding and add SMPTE time codes.
Usage: UncompAVIToWMV -i <INPUT_FILE> -o <OUTPUT_FILE> [-if]
[ -ps <SYSTEM_PROFILE_INDEX> | -pf <CUSTOM_PROFILE_FILE> ]
[-pe] [-sp <FILE>] [-arb] [-m] [-drm] [-smpte] [-d <TIME>]
[-attrib <NUMBER> <NAME> <TYPE> <VALUE>] [-pause]
-i <INPUT_FILE> = Uncompressed input AVI/WAV file name or if -if specified
ASCII file containing a list of uncompressed AVI/WAV files
-o <OUTPUT_FILE> = Output file name
-if = load list of AVI/WAV files from file specified by -i <INPUT_FILE>
-ps <SYSTEM_PROFILE_INDEX> = load the system profile by index
-pf <CUSTOM_PROFILE_FILE> = load custom profile by file name
-pe = expand specified profile to include all input streams
-sp <FILE> = save the current profile to the file
-arb = include arbitrary stream containing sample number
-m = use multipass encoding
-drm = enable digital rights management
-smpte = add SMPTE time code to video stream
-d <TIME> = specify the maximum duration in seconds of the output file
-attrib <NUMBER> <NAME> <TYPE> <VALUE> = add attribute to the specified stream
NUMBER = stream number for attribute: 0 - 63, 0 - all streams
NAME = name of the attribute
TYPE = data type of the attribute: string/qword/word/dword/binary/bool
VALUE = value of the attribute
-pause = wait for keypress when done
REMARK: only AVI files with uncompressed streams are accepted
