通过php的mp4文件不能作为html5视频播放 [英] mp4 file through php not playing as html5 video

问题描述

我正在尝试通过PHP输出mp4视频文件. 当通过Flash播放器(例如flowplayer)使用它时，效果很好. 但是，当我尝试将其用作html5视频标签上的源代码或直接调用php文件时，它将无法正常工作.

I am trying to output an mp4 video file through PHP. When it is used through a flash player (eg. flowplayer) it is working great. But when I'm trying to use it as a source on an html5 video tag or to call directly the php file, it doesn't work.

我使用的代码如下:

        $filesize = filesize($file);
        header("Content-Type: video/mp4");

        if ( empty($_SERVER['HTTP_RANGE']) )
        {
            header("Content-Length: $filesize");
            readfile($file);
        }
        else //violes rfc2616, which requires ignoring  the header if it's invalid
        {   
            rangeDownload($file);
        }

和rangeDownload功能来自 http://mobiforge.com/developing /story/content-delivery-mobile-devices 附录A.

即使我使用Content-Range标头(Content-Range:bytes 0-31596111/31596112)，它也停留在下载30.13 MB的视频上.

Even when I use a Content-Range header (Content-Range:bytes 0-31596111/31596112), it stucks on downloading 30.13 MB of the video.

推荐答案

最后，我找到了一种使之工作的方法

Finally I've found a way to make it work

header("Content-Type: $mediatype");

if ( empty($_SERVER['HTTP_RANGE']) )
{
    header("Content-Length: $filesize");

    $fh = fopen($file, "rb") or die("Could not open file: " .$file);

    # output file
    while(!feof($fh))
    {
         # output file without bandwidth limiting
        echo fread($fh, $filesize);
    }
    fclose($fh);
}
else //violes rfc2616, which requires ignoring  the header if it's invalid
{   
     rangeDownload($file);
}

它在php文件的直接链接和html5视频标记内起作用.
但是，为了在Flowplayer(和其他Flash/html5播放器)中工作，您需要添加mp4扩展名(例如view.php?id = XXX& file = type.mp4)

It is working in direct link of the php file and inside html5 video tag.
But in order to work in Flowplayer (and maybe in other flash/html5 players) you need to add a mp4 extension (eg. view.php?id=XXX&file=type.mp4)
