// ffmpeg command to convert video

exec("ffmpeg -i ".$directory_path_full." ".$directory_path.$file_name.".flv");

// $file_name is same file name that is being uploaded but you can give your custom video name after converting So use something like myfile.flv.

/// In the end update video name in DB
