HTML5视频无法播放

Question

我使用video标记在我的浏览器（Chrome）上播放视频。只有当文件低于（大约）135MB时，我才能使用此标记播放我的mp4视频。如果文件大于135MB，则无法播放视频（相同格式的&相同的扩展名）。任何人都知道发生了什么事以及如何解决？

我的代码来打开文件：

<?php 
    $filename=$_GET['filename']; //parameter identifying the file to be downloaded. Should not be direct path as in this simple example, rather than the id of the file's data stored in a database. You need to add that piece of code. 
    header('Content-Type: text/plain'); //set MIME type - you need to store this along your path to the file, you can get it from $_FILES['uploadedfilename']['type'] when a file is uploaded via php 
    header("Content-disposition: attachment;filename=$filename"); //advises the browser to open the file outside of the browser, not within a plugin 
    readfile($filename); //outputs the file 
?> 

我的代码来读取文件：

<video controls width="320"> 
    <source src="video_view.php?filename='.$query['v_drive'].'://upload/'.$query['c_group'].'/'.$query['c_name'].'/'.$query['v_link'].'" type="video/mp4"> 
    <source src="video_view.php?filename='.$query['v_drive'].'://upload/'.$query['c_group'].'/'.$query['c_name'].'/'.$query['v_link'].'" type="video/webm"> 
    <object type="application/x-shockwave-flash" data="eh5v.files/html5video/flashfox.swf" width="720" height="576" style="position:relative;"> 
     <param name="movie" value="assets/flashfox.swf" /> 
     <param name="allowFullScreen" value="true" /> 
     <param name="flashVars" value="autoplay=true&amp;controls=true&amp;fullScreenEnabled=true&amp;posterOnEnd=true&amp;loop=false&amp;src=video_view.php?filename='.$query['v_drive'].'://upload/'.$query['c_group'].'/'.$query['c_name'].'/'.$query['v_link'].'"" /> 
     <embed src="assets/flashfox.swf" width="320" style="position:relative;" flashVars="controls=true&amp;fullScreenEnabled=true&amp;posterOnEnd=true&amp;loop=false&amp;src=video_view.php?filename='.$query['v_drive'].'://upload/'.$query['c_group'].'/'.$query['c_name'].'/'.$query['v_link'].'" allowFullScreen="true" wmode="transparent" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer_en" />   
    </object> 
    Your browser does not support the video element. 
</video>

最后我发现从谷歌此链接：http://licson.net/post/stream-videos-php/可用于从播放任何视频PHP文件，它的工作非常好。
