Need help with simple ffmpeg class

[inutero]

Ok, I'm rather new to php so sorry for that.

 

I'm trying to use ffmpeg to convert videos to flv, I can get it to work but I want the input and output files to be variables.

 

My current code looks like this:

 

 
<?php
$source="cat.mpeg";
$destination="cat.flv";

class convert
{

	function convert($source,$destination)
	{
	// this will create a .flv from .wmv
	// you can chnage the other parameters if you are an expert 
	exec("ffmpeg -i -f {$source}  {$destination}");

	}
}




$jf=new convert($source,$destination);


?>

 

The problem is the variables don't seem to be read, I'm pretty sure it is the way I have written them. I know ffmpeg works because if I replace the $source & $destination the conversion works fine.

 

Any tips on how to correct this?

You are not declaring the variables inside the class, so I don't think it will work. Try this instead...

 

<?php
class convert {
    var $source;
    var $destination;
    function convert() {
        // this will create a .flv from .wmv
        // you can chnage the other parameters if you are an expert 
        exec("ffmpeg -i -f {$this->source}  {$this->destination}");
    }
}
$jf=new convert();
$jf->source="cat.mpeg";
$jf->destination="cat.flv";
$jf->convert();
?>

 

That should work if it is loading the files correctly, but don't hold your breath, I haven't tested it. If not, there is an OOP forum, which may help a little more, as people in their are more familiar with classes and other OOP stuff.

It doesn't work but thanks anyway, I'll ask in the O.O.P board.
