Cambiar SRT a xml con inicio y duración

Bueno, se me presentaron dos problemas:
1) pasar subtítulos SRT a xml y
2) pasar el inicio – fin de los subs por inicio y duración

Funciona así, uno pone el SRT en el index.html y devuelve un xml. Hubo un problema en windows por lo cual cambie el encoding.

Acá va el código html:

<html>
<body>

<form action="mots_xml_mac.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>

</body>

Acá va el código php:

<?php

// script to convert multi-line srt caption files to new-format (02-05-08) tt XML caption files
$use_cdata_tags = false;
$debug_output = true;

// the directory to write the new files in
// it must exist, be writeable, and be outside of the directory that is being scanned
$new_directory = '../temp/';

//foreach(new RecursiveIteratorIterator($it) as $file)

Para que funcione en windows hay que hacer:

< //    print(iconv(‘UTF-8’, ‘Windows-1252’, $ttxml));

>     print(iconv(‘Windows-1252′,’UTF-8’ ,$ttxml));

Esto funciona con el subtitle workshotp y no me acuerdo el que funciona para windows.

Enjoy.
