codes to convert from avi to asf

Question

No matter what library/SDK to use, I want to convert from avi to asf very quickly (I could even sacrifice some quality of video and audio). I am working on Windows platform (Vista and 2008 Server), better .Net SDK/code, C++ code is also fine. :-)

I learned from the below link, that there could be a very quick way to convert from avi to asf to support streaming better, as mentioned "could convert the video from AVI to ASF format using a simple copy (i.e. the content is the same, but container changes).". My question is after some hours of study and trial various SDK/tools, as a newbie, I do not know how to begin with so I am asking for reference sample code to do this task. :-)

(as this is a different issue, we decide to start a new topic. :-) )

Issue with streaming AVI files

thanks in advance, George

EDIT 1:

I have tried to get the binary of ffmpeg from,

http://ffmpeg.arrozcru.org/autobuilds/ffmpeg-latest-mingw32-static.tar.bz2

then run the following command,

C:\software\ffmpeg-latest-mingw32-static\bin>ffmpeg.exe -i test.avi -acodec copy
 -vcodec copy test.asf

Maybe you could use FFMPEG and run a command like this (I haven't tried):

ffmpeg.exe -i test.avi -acodec copy -vcodec copy test.asf
