O.P. FFMPEG-PHP: converting videos
I want to convert any videos to FLV format.
code:
<?php
convertToFlv( "test.avi", "test.flv" );

function convertToFlv( $input, $output ) {
   echo "Converting $input to $output<br />";
   $command = "ffmpeg -i $input -s 320x240 -ar 44100 -r 12 $output";
   echo "$command<br />";
   shell_exec( $command );
   echo "Converted<br />";
}
?>
For some reason, it doesn't output anything.
What am I missing here?

ffmpeg
ffmpeg support (ffmpeg-php)     enabled
ffmpeg-php version              0.5.0
libavcodec version              Lavc51.32.0
libavformat version             Lavf51.8.0

shell_exec() isn't supposed to output anything... try putting an echo in front of it. :p

What I meant with "anything" was the output file :p

Anyways, I added an echo there, and it's still the same.
It even doesn't say whether the library/command is unavailable or something.

I have a strange feeling that I have to call it in another way (creating a new object, etc.).

I thought that might be the case, but still, there should be some kind of error message if it fails... :-/

:S

Try a simple test...
code:
<?php

$output = shell_exec("ffmpeg -formats");

echo "<pre>";
print_r($output);
echo "</pre>";

?>
If successful, that should display info about the formats FFmpeg supports, and confirm that you can run it. If it doesn't work, I'm not sure what the problem is... maybe you have to specify the absolute path to the FFmpeg binary or something.

I doubt it... the ffmpeg-php extension is only "for accessing and retrieving information from video and audio files." It doesn't do conversion. Besides, that script I linked to in the shoutbox simply calls shell_exec()...

I tried it earlier, and it printed nothing.

Tried with /usr/local/bin/ffmpeg. It didn't work, either :p
I will confirm my hosting provider soon.

So FFMPEG-PHP is not the same as FFMPEG?

Correct, ffmpeg is a command-line program that has nothing to do with PHP. ffmpeg-php is a PHP extension that incorporates some of the capabilities of ffmpeg.

Edit: I tested your convertToFlv() function on my localhost (Win32) and it worked fine. All I had to do was change the path to ffmpeg.exe.

RE: FFMPEG-PHP: converting videos
its 2009 ! lol

this is what i'm looking for but , i really hate flv ! flash now supports h264 !

how can i change this,
---------------------------------------------------------------------------------------
<?php
convertToFlv( "test.avi", "test.flv" );

function convertToFlv( $input, $output ) {
   echo "Converting $input to $output<br />";
   $command = "ffmpeg -i $input -s 320x240 -ar 44100 -r 12 $output";
   echo "$command<br />";
   shell_exec( $command );
   echo "Converted<br />";
}
?>

----------------------------------------------------------------------------------------------------------

to support this,

mencoder video.mpeg -o output.mp4 -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encopts bitrate=300:level_idc=41:bframes=3:frameref=2: nopsnr: nossim: pass=1: threads=auto -oac mp3lame

i'm not sure if mencoder can be called through like php. which runs with ffmpeg-php i believe.

i just want to encode to h264 video, mp3 audio, and output container to be ogg or ogm.

and yes i do notice this post was made years ago lol who knows maybe i get reply

   echo "$command<br />";
   shell_exec( $command );
   echo "Converted<br />";
}
?>

How about that? Uses the mencoder command you wanted.

also remember if you're passing an argument into the command line, use http://php.net/escapeshellarg to make it safeish ;>

Yeah thanks dt, slipped my mind.

code:
<?php
convertToFlv( "test.avi", "test.flv" );

function convertToFlv( $input, $output ) {
   $input = escapeshellarg($input);
   $output = escapeshellarg($output);
   echo "Converting $input to $output<br />";
   $command = "mencoder $input -o $output -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encopts bitrate=300:level_idc=41:bframes=3:frameref=2: nopsnr: nossim: pass=1: threads=auto -oac mp3lame ";
   echo "$command<br />";
   shell_exec( $command );
   echo "Converted<br />";
}
?>
