 $sub_file = str_ireplace(".avi", ".srt", $dir.$file);
 $idx_file = str_ireplace(".avi", ".idx", $dir.$file);
 $thumb_file = str_ireplace(".avi", ".jpg", $dir.$file);
 $out_file = str_ireplace(".avi", ".mp4", $dir.$file);
 flv_convert_get_thumb($dir.$file, $sub_file, $idx_file, $thumb_file, $out_file);

function flv_convert_get_thumb($in, $in_sub, $in_idx, $out_thumb, $out_vid){
 // get thumbnail
 $cmd = 'ffmpeg -v 0 -y -i '.$in.' -vframes 1 -ss 250 -vcodec mjpeg -f rawvideo -s 286x160 -aspect 16:9 '.$out_thumb;
 $res = shell_exec($cmd);
 // $res is the output of the command
 // transcode video
$cmd = 'mencoder '.$in.' -o '.$out_vid.' -sub '.$in_sub.' -subfont-text-scale 3.0 -subpos 99 -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encop$
