[MPlayer-users] help converting avi to flv (my command fails)

[Christopher J. Bottaro]

Hello,
I got the following command off a blog, but it fails when I try to run it:
mencoder test1.avi -o testflv -of lavf -oac mp3lame -lameopts
abr:br=64 -srate 22050 -ovc lavc -lavfopts
i_certify_that_my_video_stream_does_not_use_b_frames -lavcopts
vcodec=flv:keyint=50:vbitrate=300:mbd=2:mv0:trell:v4mv:cbp:last_pred=3

with error:

You have certified that your video stream does not contain B frames.
REMEMBER: MEncoder's libavformat muxing is presently broken and will
generate
INCORRECT files in the presence of B frames. Moreover, due to bugs MPlayer
will play these INCORRECT files as if nothing were wrong!

CAN'T GET SPECIFIED FORMAT
Cannot initialize muxer.

Any ideas?  Mplayer can play flv files just fine on my system and I have all
the win32 codecs installed.

Thanks for the help.
