使用php文件读取视频stream并用flowplayer播放

php文件读取视频留可以原创文章:

http://richbellamy.com/wiki/Flash_Streaming_to_FlowPlayer_using_only_PHP

 

下面我想说说我是怎么配置成功的:

1. 下载读取视频stream的streamer.php文件:

php代码如下,仔细红色的配置部分:

 //
 // you can configure these settings to point to video files outside the public html folder.
 //------------------------------------------------------------------------------------------
 
 // points to server root

//定义你的根目录,一般为你的网站根目录下面的第一个文件,下面这个配置则代表的是http://www.malacity.net/example. 注意前面都没有斜杠

2 . 上传一个myvideo.flv文件到videos文件夹中

 

3. 配置完后你可以通过测试:

http://www.malacity.net/streamer.php/myvideo.flv

查看是否可以下载你所上传的文件?如果能下载则表面你创建的tream成功了.

 

4. 配置flowplayer:注意红色说明.
