[MEncoder-users] how to set dimensions for FLV?

[Nick Fedchik]

Can anybody help me to correct mencoder parameters?
Mencoder build from Subversion code.
I tried to convert MPEG to FLV and got an error:

Command line is:
/usr/local/bin/mencoder testfeed.ts -o ./output-test.flv -of lavf -lavfopts 
i_certify_that_my_video_stream_does_not_use_b_frames -ovc lavc -lavcopts 
vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 
22050 -forceidx -demuxer lavf -oac faac -ac ffmp3
