[Libav-user] Q regarding ffmpeg command to change bit rate of wmv file

I have a VC-1 file at Simple profile, medium level, bit rate = 236 kbps. I
use the following command to change bit rate and frame rate of file

ffmpeg -i input.wmv -b 128k -r 15 output.wmv

When I check the information of output file, it shows a file with MPEG-4
Visual format and codec MP43. Is there any way to produce an output file
with the  same VC1 Simple profile, medium level information as input file
using ffmpeg?

I tried using -f vc1 switch in the command but thats only for having raw vc1
video output.
