In this post will show you how to upload and convert a video file to FLV using FFmpeg in CodeIgniter Application.

If your hosting server in windows , you need to download FFmpeg.exe file from FFmpeg official website, and put it in your root folder.

if your hosting server in Linux , you need to install FFmpeg, to check FFmpeg availability print phpinfo(),Find FFmpeg on that window if it doesn’t found then it means your server has not installed FFmpeg.

Form View – This is for uploading video

Controller function

upload->initialize($config);
	$this->load->library('upload', $config);

	if(!$this->upload->do_upload()) {
		// If there is any error
		$err_msgs .= 'Error in Uploading video '.$this->upload->display_errors().'
';
	} else {
		$upload_data= $this->upload->data();
		$video_path = $upload_data['file_name'];
		
		// ffmpeg command to convert video
		exec("ffmpeg -i ".$upload_data['full_path']." ".$upload_data['file_path'].$upload_data['raw_name'].".flv"); 
	 
		/// In the end update video name in DB 
		$array = array('video' => $upload_data['raw_name'].'.'.'flv');
		$this->db->set($array);
		$query = $this->db->update('videos_tbl'); 	
	}
}
?>

Requirements

1.Create folder called “video” in the root folder

2.sometimes mime types has to be added for flv and wmv.so add the following lines into config->mimes.php file

'wmv'   =>     array('video/wmv', 'video/x-ms-wmv', 'flv-application/octet-stream', 'application/octet-stream'),
'flv'   =>     array('video/flv', 'video/x-flv','flv-application/octet-stream', 'application/octet-stream'),

3.Need to increase the maximium upload size of php.ini if you need to upload a video size of more than 2MB (Deafult is 2M).
change following line in php.ini (Here I have add 10M.)
upload_max_filesize = 10M

How do i Create video thumbnails using ffmpeg?

we can generate thumbnails in Linux using ffmpeg with single command shown below

ffmpeg  -itsoffset -5  -i pathToVideoFile.avi -vcodec mjpeg -vframes 1 -an -f rawvideo -s 400x600 path/To/Destination/Folder/test.jpg

This command generates a 400×600 sized thumbnail at the 5th second in the video.
