If you are using Linux server, Use print phpinfo() function to check whether your hosting server has FFmpeg installed or you need it to be installed.

Use the below code for uploading and converting the video file in Codeigniter.

$file    = 'video_file';
$config['upload_path']  = './video_folder/';
$config['allowed_types']  = 'mov|mpeg|mp3|avi';
$config['max_size']  = '50000';
$config['max_width']    = '';
$config['max_height']    = '';
$this->upload->initialize($config);
$this->load->library('upload', $config);
if(!$this->upload->do_upload($file))
{
 // If there is any error
 $err_msgs .= 'Error in Uploading video '.$this->upload->display_errors().'
';
}
else
{
 $data=array('upload_data' => $this->upload->data());
 $video_path = $data['upload_data']['file_name'];
  $directory_path   = $data['upload_data']['file_path'];
 $directory_path_full      = $data['upload_data']['full_path'];
 $file_name   = $data['upload_data']['raw_name'];
 // ffmpeg command to convert video
 exec("ffmpeg -i ".$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
 $array = array(
  'video' => $file_name.'.'.'flv',
  );
 $this->db->set($array);
 $this->db->where('id',$id); // Table where you put video name
 $query = $this->db->update('user_videos');
}
