this is what I had before and have right now. I believe this is modified code from whats in install package:

Code:
<?php
$cmd_mencoder = "$config[mencoder] '$video_src' -o $video_flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames";

$cmd_all = $cmd_mencoder;

$convert_3gp = $cmd_all;

$convert_mp4 = $cmd_all;

$convert_mov = $cmd_all;

$convert_asf = $cmd_all;

$convert_mpg = $cmd_all;

$convert_avi = $cmd_all;

$convert_mpeg = $cmd_all;

$convert_wmv = $cmd_all;

$convert_rm = $cmd_all;

$convert_dat = $cmd_all;
