Convert to FLV?

I think I have already writen about that somewhere on the forum and there were good answers, but here is what I have used for several projects. You will need mencoder installed on the server and flvtool2 to fix the time of the flv movie.

exec("mencoder {$in_file_path} -o {$in_file_path}.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=9600:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -srate 22050");

exec("flvtool2 -Uv {$in_file_path}.flv {$in_file_path}_res.flv");

PHP:

But I think it is a good idea to write cgi script and run it by cron. This will prevent server overloads and script will encode only 1 file at a time . Just do not forget to check that script is not runing already.

 

With this function that you have wrote krakjoe which is great thanks, how will i get this to interact with a users upload will i have to run the function on the file after the user uploads? Is there a way to run this on the fly?

 

If the files you were converting were on a server somewhere, then yeah maybe, but when you upload files to a server php cannot interact with those files untill they are completely uploaded, nor can ffmpeg.

If the files were on another server, it could (may)be done, you could use curl callbacks to write the data of the video to ffmpegs stdin and have ffmpeg write it's stdout back to another php class for streaming or zipping or just have ffmpeg write to the filesystem with the data it produces.

It's highly unlikely you're talking about the latter.....

 

Cheers for that it works great. The only thing i need to do is add the feature so that a thumbnail is taken of the video as well as converting it. Any idea how this can be done?

 

<?
//nick_thumb( string $video, [ string $out, [ string $time, [ string $format ]]] )
function nick_thumb( $video, $out = null, $time = '0.001', $format = 'image2' )
{
	if( is_null( $out ) ) $out = preg_replace('#\.(.*?[^\.])$#si', '.jpg', basename( $video ) );
	
	exec( sprintf( 'ffmpeg -i %s -f %s -t %s %s',
					$video,
					$format,
					$time,
					$out ), $output, $return );
	return !$return ? true : false;
}
if( nick_thumb( 'stealingthumbnails.avi' ) ) :
	echo "Thumnail created\r\n";
else:
	echo "No thumbnail created\r\n";
endif;
//nick_thumb( string $video, [ string $out, [ string $time, [ string $format ]]] )
?>

PHP:

 

I understand that i need this software to be installed on my server to convert the movie files to flv and create a thumbnail image.

My question is this : do i need to add a code to my script so that it will automatically add the image files to the movie clips and to convert the movie files?

 

Thanks a lot for that Joe,

Just one more question though. How would i go about saving that image to e.g. videos/thumbs on my server with that function you wrote?

 

2nd [ 1st optional ] paramter of the function is the output image

<?
//nick_thumb( string $video, [ string $out, [ string $time, [ string $format ]]] )
function nick_thumb( $video, $out = null, $time = '0.001', $format = 'image2' )
{
    if( is_null( $out ) ) $out = preg_replace('#\.(.*?[^\.])$#si', '.jpg', basename( $video ) );
   
    exec( sprintf( 'ffmpeg -i %s -f %s -t %s %s',
                    $video,
                    $format,
                    $time,
                    $out ), $output, $return );
    return !$return ? true : false;
}
if( nick_thumb( 'stealingthumbnails.avi', 'videos/thumbs/stealingthumbs.jpg' ) ) :
    echo "Thumnail created\r\n";
else:
    echo "No thumbnail created\r\n";
endif;
//nick_thumb( string $video, [ string $out, [ string $time, [ string $format ]]] )
?>

PHP:

@monsterclips, sorry, I don't understand the question .....

 

Sorry, i forgot to add the list of software

GD Library 2 or higher
FFmpeg (http://ffmpeg.mplayerhq.hu)
Mplayer + Mencoder (http://www.mplayerhq.hu/design7/dload.html)
Flv2tool (http://inlet-media.de/flvtool2)
Libogg + Libvorbis (http://www.xiph.org/downloads)
LAME MP3 Encoder (http://lame.sourceforge.net)


I understand if these software is installed on my server it will
convert my avi,mpeg,wmv ...ect to flv but do i need to add some
sort of code in my script so that it knows where to add the image files
and so on?

 

show me script .....

 

Thanks for the fast reply Joe and sorry to bother you again but i am having problems. This is how i have set-up my code:

   

       //get the file extension.
       $getExt = explode ('.', $file_name);
       $file_ext = $getExt[count($getExt)-1];
	   
       //create a random file name
       $rand_name = md5(time());
       $rand_name= rand(0,999999999);
	   
	//upload the big image
    	move_uploaded_file ($file_tmp, "upload/videos/$rand_name.$file_ext");

		
//convert video to .flv
		ffmpeg_c("upload/videos/$rand_name.$file_ext","upload/flv/$rand_name.$file_ext.flv");

		 //Take a thumbnail
		if( nick_thumb( 'upload/flv/$rand_name.$file_ext.flv', 'upload/thumbs/$rand_name.jpg' ) ) :
			echo "Thumnail created\r\n";
		else:
			echo "No thumbnail created\r\n";
		endif; 

Code (markup):

It uploads, converts and does every thing fine but when it gets to the thumbnail it displays "No thumbnail created"

Any ideas what i am doing wrong?

Cheers,
Adam

Works a treat.. Thanks everyone

 

Here is my site:

Humour

 

no good, I mean code

 

the source code for my website is here:

The PHP code, not the HTML.

The code of THIS script.

 

Does anyone know how to play .flv file within a webpage?

Thank you for that. From reading it appears that you have to buy this, and is only a free trial . Is there no way to do this free?
