mp4 from PHP - Not playing in HTML5 Video tag

问题

I am using the video tag to play videos.

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>

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.

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\n");
 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();
 }

So what am i doing wrong ?

回答1:

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.

回答2:

You will have to echo the path after retrieving it and pass it to the 'src' attribute of the Video Tag of HTML5. Your Current Strategy won't work well, i hope...

For example,

<source src="<?php echo getMp4VideoUrl(); ?>" type='video/mp4'/>

回答3:

The browser identifies the video content from the header sent to it with the request. Just manipulate the header and keep the PHP extension. It will work perfect
