Hi Lista
I'm trying to figure how I can turn MP3 files into FLV files on the fly
using PHP.
I'm having a server and I can install 3rd party software in order to
accomplish this conversion.
I have never dealt before with music file comression or anything similar so
I don't know what I should look after or where I should look.
Any idea would be very appreciated!
Thanks!

You may want to use some sort of caching, converting media formats is very
computationally demanding. You could use FFMPEG to do the conversion.

I thought of using FFMPEG but I have a bit of experience with it.
Any links or more specific directions would be great.

I would also batch it. Keeping a user waiting (unless you have a
"please wait..." screen, which still can take some time and be a bad
user experience) in my experience hasn't been ideal and won't scale
very well.

I don't have to let the user wait. The conversions will be done once 3 hours
using a cron job, they all will be listed in a mysql database.

These is a PHP binding for FFMPEG here:
http://ffmpeg-php.sourceforge.net/, though most of the tutorials you will
find are for the C API, for example http://www.dranger.com/ffmpeg/, which
demonstrates how to implement a media player.
Personally I would just skip using the API and use the CLI program to
convert the media, and cache/ serve from the resulting file, much easier
to implement.

+1
the ffmpeg-php module would be great if it got into PECL and got more
support. right now it has some flaws and is not fully featured. it can
be useful for things like identifying media but i am not sure how well
it would be for conversion and other things. A client of mine had a
conversion script created which leveraged ffmpeg-php for
identification of aspect ratio and other things, but then went to
system() for the conversion calls.

system("ffmpeg -i $inputfile output.wav"); i think is really a basic
example. tweak the audio specifics as you wish (man ffmpeg - it's got
a ton of options)

This is a very small framework for PHP inspired by the framework of Fabien
Potencier (http://twitto.org/).
<?php
$c = $_GET['c']; //getting controller name
$a = $_GET['a']; //getting action name
if (@include_once('c/'.$c.'.php'))
{
$c = new $c; //controller instance
if (method_exists($c,$a))
$c->$a(); //invoking the action
else
die("A !f"); //controller not found
}
else die("C !f"); //action not found
?>
$c=$_GET['c'];$a=$_GET['a'];if(@include_once('c/'.$c.'.php')){$c=new$c;if(method_exists($c,$a))$c->$a();else
die("A !f");}else die("C !f");

I'm still not sure I get it. What about a Scatter chart with the
points connected? Would that be reasonable? With this you'd specify a
max X value of say 365 to represent a year, and then plot the values
based on that, ie: 67,57|234,80|57,89 ad infinitum. Then just connect
the points. If there's a pattern, it would become apparent.

Thanks. That's what I thought. I'm using it to back up my working directory to
another
drive, and a 3 second limit wasn't long enough, so one of the directories must
take longer
than I expected to copy.

I have just written a recursive backup program, and used a slightly different
exclusion
procedure:
$exclusions = array ('...drupal' => true, 'Images' =>'true', .... );
if (!isset($exclusions[$file])) { [copy file to backup ] }
This looks simpler, and therefore quicker, but I suspect it is just putting the
complexity
out of sight!

I have another need for a SCA tool.
Is there an existing tool similar to a broken link checker, but
instead of looking for links, it would look for "include" and
"require" type commands and list a hierarchy of all files used in the
project, starting from a given input file?
It should get a list of files used in a production deployment
beginning from say "index.php", and compare that to a list of files
used in a project undergoing development from say "index_dev.php"? At
a minimum, (from what I can think of), it would have to resolve
define's that may be referenced in "include/require" as well as links
as in a broken link checker tool.

One final update.
The way one sets the path to required files is very important. I found it is
best to use instead of relative paths.
