我在服务器端有一个带有laravel(流明)的ios应用程序。我正在尝试在应用程序上播放服务器中的视频。
我使用的播放器播放具有直接链接(例如,vine视频链接)的视频,但是,当我在本地服务器上保存相同的vine视频时,应用程序将无法播放视频。实际上,当我使用api路由尝试视频时,令人惊讶的是它在Chrome上播放了视频!但是在应用程序端,我收到错误消息:
服务器配置不正确-12939
(请注意,如果我将相同的mp4文件复制到xCode项目中,然后将其添加到“复制捆绑资源”上,然后尝试使用fileWithPath,它就可以正常工作。因此,我相信它绝对是由服务器而非vidoo文件/编解码器引起的。
我的路线: $app->get('/player/{filename}', 'PlayerController@show');
方法:
public function show ($filename) { $this->playVideo($filename, 'recordings'); } public function playVideo($filename, $showType) { if (file_exists("../uploads/" . $showType . "/" . $filename)) { $finfo = finfo_open(FILEINFO_MIME_TYPE); $type = finfo_file($finfo, "../uploads/" . $showType . "/" . $filename); header("Content-Type: " . $type); readfile("../uploads/" . $showType . "/" . $filename); } }
回顾我的问题,该视频正在Chrome上播放,但在移动应用上收到“ 12939”-“服务器配置不正确”。
编辑:
我尝试使用Apple文档中提到的方法:
curl --range 0-99 http://myapi.dev/test.mp4 -o /dev/null
但是文档说:
“如果工具报告它下载了100个字节,则媒体服务器正确处理了字节范围请求。如果它下载了整个文件,则可能需要更新媒体服务器。”
我收到了100%,它为我下载了整个文件,所以我认为这是我的问题。但是我不确定如何克服这个问题?我究竟做错了什么?我该怎么办?
最后,这解决了我的问题:
放置到VideoController:
public function streamVideo() { $video_path = 'somedirectory/somefile.mp4'; $stream = new VideoStream($video_path); $stream->start(); }
然后在中创建一个文件app > helpers > VideoStream.php
:
path = $filePath; } /** * * Open stream * */ private function open() { if (!($this->stream = fopen($this->path, 'rb'))) { die('Could not open stream for reading'); } } /** * * Set proper header to serve the video content * */ private function setHeader() { ob_get_clean(); header("Content-Type: video/mp4"); header("Cache-Control: max-age=2592000, public"); header("Expires: ".gmdate('D, d M Y H:i:s', time()+2592000) . ' GMT'); header("Last-Modified: ".gmdate('D, d M Y H:i:s', @filemtime($this->path)) . ' GMT' ); $this->start = 0; $this->size = filesize($this->path); $this->end = $this->size - 1; header("Accept-Ranges: 0-".$this->end); if (isset($_SERVER['HTTP_RANGE'])) { $c_start = $this->start; $c_end = $this->end; list(, $range) = explode('=', $_SERVER['HTTP_RANGE'], 2); if (strpos($range, ',') !== false) { header('HTTP/1.1 416 Requested Range Not Satisfiable'); header("Content-Range: bytes $this->start-$this->end/$this->size"); exit; } if ($range == '-') { $c_start = $this->size - substr($range, 1); }else{ $range = explode('-', $range); $c_start = $range[0]; $c_end = (isset($range[1]) && is_numeric($range[1])) ? $range[1] : $c_end; } $c_end = ($c_end > $this->end) ? $this->end : $c_end; if ($c_start > $c_end || $c_start > $this->size - 1 || $c_end >= $this->size) { header('HTTP/1.1 416 Requested Range Not Satisfiable'); header("Content-Range: bytes $this->start-$this->end/$this->size"); exit; } $this->start = $c_start; $this->end = $c_end; $length = $this->end - $this->start + 1; fseek($this->stream, $this->start); header('HTTP/1.1 206 Partial Content'); header("Content-Length: ".$length); header("Content-Range: bytes $this->start-$this->end/".$this->size); } else { header("Content-Length: ".$this->size); } } /** * * close curretly opened stream * */ private function end() { fclose($this->stream); exit; } /** * * perform the streaming of calculated range * */ private function stream() { $i = $this->start; set_time_limit(0); while(!feof($this->stream) && $i <= $this->end) { $bytesToRead = $this->buffer; if(($i+$bytesToRead) > $this->end) { $bytesToRead = $this->end - $i + 1; } $data = fread($this->stream, $bytesToRead); echo $data; flush(); $i += $bytesToRead; } } /** * * Start streaming video content * */ function start() { $this->open(); $this->setHeader(); $this->stream(); $this->end(); } }
