Mplayer conversion error

Hello,

I have installed mplayer and ffmpeg on the vps. When I run the following command on the shell

mencoder '/home/xxxx/public_html/video/Muchas-Chiquitas-Muy-Ricas.wmv' -o /home/xxxx/public_html/flvideo/12311637692026487648.flv -of lavf -oac mp3lame -ovc lavc -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:l ast_pred=3 -srate 22050 -ofps 24 -vf harddup

I am getting the following error

================================================== ========================
** MUXER_LAVF ************************************************** ***************
If you wish to use libavformat muxing, you must ensure that your video stream
does not contain B frames (out of order decoding) and specify:
-lavfopts i_certify_that_my_video_stream_does_not_use_b_fram es
on the command line.
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!

Cannot initialize muxer.


Please advice.

You are using an older version of mplayer. Open your video_conversion.php file in the include directory and comment out the first mencoder line. Then, uncomment the second mencoder line. This should fix the problem.
