Hi,
at first sorry for the bad english but i hope you can understand my problem.

I've two files on my webserver "test.mp4" and "test.php".

"test.mp4" is a video file that plays well on iphone when i open it in safari

"test.php" is a php script that set the headers of the mp4 video file and then sends the file content to the browser

"test.php" plays well on my pc, but the iphone brings the player up and then says: "this video can't be played"

so i captured the traffic of both requests (to "test.mp4" & "test.php") with wireshark and followed the tcp stream, but can't see anything wrong.

so does anyone else have an idea ?

the content of "test.php" is below, as well as the wireshark output.

"test.php":

PHP Code:

<?php
    header("HTTP/1.1 200 OK");
    header("Date: Tue, 19 May 2009 20:55:26 GMT");
    header("Server: Apache/2.2.3 (Debian) mod_mono/1.2.1 mod_python/3.2.10 Python/2.4.4 PHP/5.2.9-0.dotdeb.1 with Suhosin-Patch mod_ssl/2.2.3 OpenSSL/0.9.8c mod_perl/2.0.2 Perl/v5.8.8");
    header("Last-Modified: Tue, 19 May 2009 20:50:33 GMT");
    header("ETag: \"5696da-54ac4-fdb5840\"");
    header("Accept-Ranges: bytes");
    header("Content-Length: 346820");
    header("Content-Type: video/mp4");
    passthru("cat test.mp4");
?>

Solution: byte-ranges !!

My PHP-Script didn't support byte-ranges and the Quicktime-Player (IPhone & Windows) needs this to play the video.

A solution is here Content Delivery for Mobile Devices | mobiForge (function rangedDownload) but since this would only work with files and not with on the fly encoding it's nothing for me
