[MEncoder-users] What may be the problem: Unknown suboption i_certify_that_my_video_stream_does_not_use_b_frames

[Berkay Unal]

Hi ,
I am trying the command line as follows but i always get a error saying
that  "Unknown suboption
i_certify_that_my_video_stream_does_not_use_b_frames"

Here is the command line. What might be the problem. Any help would be
grateful;
------
mencoder /home/deneme/video/6.mpg -o /home/deneme/flvideo/1.flv of lavf -oac
mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts
vcodec=flv:vbitrate=9600:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -lavfopts
i_certify_that_my_video_stream_does_not_use_b_frames -srate 22050
--------


Thanks
