来自 PHP 的 mp4 - 不在 HTML5 视频标签中播放 [英] mp4 from PHP - Not playing in HTML5 Video tag

问题描述

我正在使用视频标签播放视频.

I am using the video tag to play videos.

我使用 php 文件进行播放，如下所示:

I using php files for the playback like this:

    <video id="playvideo" preload="auto" width="845" height="395" 
    poster="http://video-js.zencoder.com/oceans-clip.png">

    <source src="../getvideo_webm.php" type='video/webm' />
    <source src="../getvideo_mp4.php" type='video/mp4'/>
    <source src="../getvideo_ogv.php" type='video/ogg' />

    </video>

当我直接在浏览器中查看所有 .php 文件时，它们都可以正常播放.但上述所有 .php 作为源文件的设置将无法播放.如果我提供一个直接的 .mp4 源，它会正常播放.

All .php files are playing fine when i check them directly in the brower. But the above setup with all .php as source files will not play. If i give a straight .mp4 source it will play fine.

getvideo_mp4.php 如下所示:

The getvideo_mp4.php looks like this:

 $path = 'oceans-clip.mp4';
 if (file_exists($path))
 {
 $size=filesize($path);
 $fm=@fopen($path,'rb');
 if(!$fm) {
 // You can also redirect here
 header ("HTTP/1.0 404 Not Found");
 die();
 }
 $begin=0;
 $end=$size;
 if(isset($_SERVER['HTTP_RANGE'])) {
 if(preg_match('/bytes=h*(d+)-(d*)[D.*]?/i',   
 $_SERVER['HTTP_RANGE'],$matches)){
 $begin=intval($matches[0]);
 if(!empty($matches[1])) {
 $end=intval($matches[1]);
 }
 }
 }
 if($begin>0||$end<$size)
 header('HTTP/1.0 206 Partial Content');
 else
 header('HTTP/1.0 200 OK');
 header("Content-Type: video/mp4");
 header('Accept-Ranges: bytes');
 header('Content-Length:'.($end-$begin));
 header("Content-Disposition: inline;");
 header("Content-Range: bytes $begin-$end/$size");
 header("Content-Transfer-Encoding: binary
");
 header('Connection: close');
 $cur=$begin;
 fseek($fm,$begin,0);
 while(!feof($fm)&&$cur<$end&&(connection_status()==0))
 { print fread($fm,min(1024*16,$end-$cur));
 $cur+=1024*16;
 usleep(1000);
 }
 die();
 }

那我做错了什么?

推荐答案

上面的代码正在运行.在我更改 .php 文件的 src url 后，它确实有效.现在它在 moz 中播放，即 chrome，只有 php 文件作为视频标签中的源.

The above code is working. After i changed the src url for .php files, it did actually work. Now it plays in moz, ie, chrome with only php files as sources in the video tag.
