[omz1990]

hello, i am getting a file conversion error. when i upload a flv video, it works fine and plays, but when any other format, the video fails to convert. here is a log of one of the mp4 file i tried to convert.
i tried some of the methods posted in other threads, but none worked.
any help would be appreciated. thanx.

an update...
this is the video_conversion.php im using...

<?php

$cmd_ffmpeg = "$config[ffmpeg] -i '$video_src' -acodec libmp3lame -ar 22050 -ab 32 -f flv $video_flv";

//New Mplayer codec
$cmd_mencoder = "$config[mencoder] '$video_src' -o $video_flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=$bit_rate:mbd=2:mv0:trell:v4mv :cbp:last_pred=3 -srate 22050 -ofps 24 -vf harddup,hqdn3d=2:1:2,scale=640:464";

$cmd_all = $cmd_mencoder;

$convert_3gp = $cmd_all;
$convert_mp4 = $cmd_mp4_h264;
$convert_mov = $cmd_all;
$convert_asf = $cmd_all;

$convert_avi = $cmd_all;
$convert_mpeg = $cmd_all;
$convert_wmv = $cmd_all;
$convert_rm = $cmd_all;
$convert_dat = $cmd_all;

i also tried using this code as the conversion code...
$cmd_mencoder = "$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:l ast_pred=3 -srate 22050 -lavfopts i_certify_that_my_video_stream_does_not_use_b_fram es";

Look like this convert code is not working on your server. Try running the convert command in command promt and see if it works. If not you need to look into ffmpeg installation. Mostly it is not installed with libx264 needed for mp4 videos.
