Here's what I tried while logged in as root (copied from debug.txt)

Code:
/usr/local/bin/mencoder /home/thewall_net/public_html/video/9.mpg -o /home/thewall_net/public_html/flvideo/9.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
Here's the error I got:
Code:
MPlayer was compiled without libmp3lame support.
-lameopts is not an MEncoder option
Meanwhile, if I locate libmp3lame.so:

Code:
[root@clicker1 lame-3.97]# locate libmp3lame.so
/usr/lib/libmp3lame.so.0
/usr/local/lib/libmp3lame.so.0.0.0
/usr/local/lib/libmp3lame.so.0
/usr/local/lib/libmp3lame.so
AND when I ./configure mplayer, I see this:

Code:
Checking for libmp3lame (for mencoder) ... yes 
Checking for mencoder ... yes
Real head scratcher.....
