Streaming wav-File through php

[sellfisch]

Hello everybody,

 

i try to stream a soundfile (while recording) with an php file to a embeded(vlc plugin) media player. The Problem is, that the soundfile is still growing, so it has no final filesize and php has to send everything. My actual version is:

<?php
    header('Content-Description: File Transfer');
    header('Content-Type: audio/x-wav');
    header('Content-Disposition: attachment; filename=audio.wav');
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    ob_clean();
    flush();
    $handle = fopen("audio.wav", "r");
while (!feof($handle)) {
        $buffer = fgets($handle, 4096);
        echo $buffer;
    }
fclose($handle);
    //readfile("audio.wav");

Everything works fine if the playing offset is bigger that 10-15 secounds. Otherwise the download will be aborted (i think because php thinks that the end of file is reached). But need an offset of less than 3 secounds.

I hope there is a solution without the need of a streaming server.

 

Thanks for your help

You're using fgets() which looks for \n's with a maximum of 4000 bytes read before returning.  Wave files don't require \n's so this is a silly way to write the code.  If the file isn't too big, I'd suggest looking at file_get_contents() but otherwise use something like fread() to read in 4k bytes.  fgets() isn't designed for binary files anyays so it will return ASCII characters.
