[MEncoder-users] Encoding high bitrate wmv to low bitrate wmv (Windows Mobile Devices)

[Eric Martell]

Thanks Phil. By doing 176x132 it changed the aspect to
4:3 but the bitrate remained at 828kbs. Is there any
options param I can change to take it down to 30kbs so
I can play the asset on windows mobile cell phones.

Thanks in advance.

*****command :*****
$ mencoder FLN0302W.wmv -of lavf -lavfopts
i_certify_that_my_video_stream_does_not_use_b_frames
-ofps 7 -ovc lavc -lavcopts
vcodec=wmv1:vbitrate=30:aspect=4/3 -vf scale=176:132
-oac lavc -lavcopts acodec=mp3:abitrate=48 -o
output1.wmv

*****end command *****
