如何使用PHP流媒体文件？ [英] How to stream a media file using PHP?

问题描述

我试图建立一个应用程序，我必须流媒体文件（音频和视频）到浏览器。我正在通过php读取文件并将数据发送到浏览器。

$ $ $ $ $ $ $ $ $ $ $ $ $ $> $ // HTTP / 1.1
header（Expires：Sat，26 Jul 1997 05:00:00 GMT）; //过去的日期
header（Content-Type：{$ file-> getMimetype（）}）;
header（Content-Disposition：inline; filename =。$ filename。;）;
header（Content-Length：.strlen（$ file_content））;

echo $ file_content;

除了当我尝试转发视频或音频时，每件事情都很好，（我的意思是假设当前播放位置是0:15，直接进入1:25），媒体停止，当我再次按下播放按钮时，它从头开始。

I认为问题是与缓冲，但无法弄清楚。我在做什么错误的标题或其他东西是必需的。

谢谢。

解决方案

我认为你需要实现Range头，以便客户端可以跳到文件中的特定位置。你也许可以通过嗅探玩家发送的请求。

I am trying to build an application in which i have to stream the media files (audio and video) to the browser. I am reading the file through php and send the data to browser. I am using the following code.

header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Content-Type: {$file->getMimetype()}");
header("Content-Disposition: inline; filename=".$filename.";");
header("Content-Length: ".strlen($file_content));

echo $file_content;

Every thing is working fine, except when i try to forward the video or audio, (I mean suppose current play location is 0:15 and it directly go to 1:25), media stops and when i press the play button again, it starts from the beginning.

I think the problem is with the buffering, but can't figure it out. Am i doing something wrong in header or something else is required.

Thanks.

解决方案

I think you need to implement the Range header, so that the client can skip to a specific position in the file. You can probably find out what goes wrong by sniffing the request the player sends.
