php - 如何为 jw 播放器脚本编码 ffmpeg，该脚本读取传递 php 文件？

Question

我已经使用这个命令对我的视频进行了编码。

$encode_comand="ffmpeg -i  $input_path -ac 1 -ab 128k -y -vcodec libx264 -vpre ultrafast -g 30 -r 30 -crf 22 $target_path &";

exec($encode_comand);

它适用于下面的脚本

    echo '<!-- START OF THE PLAYER EMBEDDING TO COPY-PASTE -->
                <div id="mediaplayer'."11111".'" style="margin:0px auto; text-align:center; width:auto; display:blog;" class="vdoplayer">JW Player goes here</div>
                <script type="text/javascript" src="jwplayer/jwplayer.js"></script>
                <script type="text/javascript">jwplayer.key="OOD7GkWbyNXOL6MbstF2Sa/YrQPgtNUPqxm5NA==";</script>
                <script type="text/javascript">
                                jwplayer("mediaplayer'."11111".'").setup({
                                flashplayer: "jwplayer/jwplayer.flash.swf",
                                file: "$video_file",                            
                                width: "'.$width.'",
                                height: "'.$height.'",
                                stretching: "uniform",
                                type: "mp4",
                                skin: "jwplayer/jwplayer-skins-free/six.xml",

                        });
                </script>
                <!-- END OF THE PLAYER EMBEDDING -->'
//$video_file="http://myhost.com/project/files/1/video/file3.mp4";

但是在我更改脚本之后

echo '<!-- START OF THE PLAYER EMBEDDING TO COPY-PASTE -->
            <div id="mediaplayer'."11111".'" style="margin:0px auto; text-align:center; width:auto; display:blog;" class="vdoplayer">JW Player goes here</div>
            <script type="text/javascript" src="jwplayer/jwplayer.js"></script>
            <script type="text/javascript">jwplayer.key="OOD7GkWbyNXOL6MbstF2Sa/YrQPgtNUPqxm5NA==";</script>
            <script type="text/javascript">
                            jwplayer("mediaplayer'."11111".'").setup({
                            flashplayer: "jwplayer/jwplayer.flash.swf",
                            file: "readfile.php",                            
                            width: "'.$width.'",
                            height: "'.$height.'",
                            stretching: "uniform",
                            type: "mp4",
                            skin: "jwplayer/jwplayer-skins-free/six.xml",
                            abouttext: "project",
                            aboutlink: "project",
                    });
            </script>
            <!-- END OF THE PLAYER EMBEDDING -->'

它不适用于我的视频编码，但我尝试了不对其进行编码的视频。

视频
尺寸:853 x 840
编解码器:H.264
帧率:每秒 30 帧
比特率 408 kbps
音频
编解码器:MPEG-4 AAC
channel :立体声
采样率:44100 Hz ์
比特率:不适用

读取文件.php 具有读取文件功能的

<?php 
    $filename= 'http://www.longtailvideo.com/jw/upload/bunny.mp4'; //can read
    $video_file = "http://myhost.com/project/files/1/video/file3.mp4"; 
    //cannot read Same file as script below

    if (file_exists($video_file)) { ob_clean(); flush(); };
    header('Content-Type: video/mp4');
    header('Content-Disposition: attachment;filename=file.mp4');
    readfile($video_file);
    ?>

谢谢

在下面:

file: "$video_file", 

添加:
