WIN32 Console Application : WMStats
========================================================================
WMStats is a sample that displays Reader and Writer statistics.
WMStats can be run in three modes :
-(f)ile : reads in a file, then writes it out to a new file, then displays DataUnitExtension info and reader and writer statistics.
-(s)erver : sends streams read from a file to a network and displays writer statistics.
-(c)lient : reads a stream sent by server, then displays reader statistics.
Multiple instances of WMStats can also be used concurrently on one machine. Start one instance as a server to send the stream to the network and then run a second instance as a client to verify that the server is streaming correctly.
Usage:
wmstats -m <mode> -i <infile> -o <output> [-s <statistics_delay>]
mode = mode : f- file, s - server or c - client
infile = WMV file name or URL for server or client mode
output = for file : WMV output file name
for server : port number
for client : not valid
statistics_delay = [sec] delay of statistics report; default 20 seconds
Samples :
file : wmstats -m f -i c:\wmroot\welcome2.asf -o c:\wmroot\test.asf
client (input: network) : wmstats -m c -i http://banhammer:32800
client (input: file) : wmstats -m c -i c:\wmroot\welcome2.asf
server : wmstats -m s -i c:\wmroot\welcome2.asf -o 32800
Sample Output:
-File Mode
