У меня есть видео на моем сервере, и я хочу передать его через html 5 видеоплеер с php. Я нашел для этого класс ( https://gist.github.com/ranacseruet/9826293 ), но он не работает для больших файлов. Что я могу сделать, чтобы правильно показывать видео?
class VideoStream { private $path = ""; private $stream = ""; private $buffer = 102400; private $start = -1; private $end = -1; private $size = 0; function __construct($filePath) { $this->path = $filePath; } /** * Open stream */ private function open() { if (!($this->stream = fopen($this->path, 'rb'))) { die('Could not open stream for reading'); } } /** * Set proper header to serve the video content */ private function setHeader() { ob_get_clean(); header("Content-Type: video/mp4"); header("Cache-Control: max-age=2592000, public"); header("Expires: ".gmdate('D, d MYH:i:s', time()+2592000) . ' GMT'); header("Last-Modified: ".gmdate('D, d MYH:i:s', @filemtime($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(); } }
Используйте это вместо этого, я нашел этот метод в http://codesamplez.com/programming/php-html5-video -streaming-tutorial
И это работает очень хорошо для меня
<?php class VideoStream { private $path = ""; private $stream = ""; private $buffer = 102400; private $start = -1; private $end = -1; private $size = 0; function __construct($filePath) { $this->path = $filePath; } /** * Open stream */ private function open() { if (!($this->stream = fopen($this->path, 'rb'))) { die('Could not open stream for reading'); } } /** * Set proper header to serve the video content */ private function setHeader() { ob_get_clean(); header("Content-Type: video/mp4"); header("Cache-Control: max-age=2592000, public"); header("Expires: ".gmdate('D, d MYH:i:s', time()+2592000) . ' GMT'); header("Last-Modified: ".gmdate('D, d MYH:i:s', @filemtime($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(); } }
Чтобы использовать этот класс, вам придется писать простой код, как показано ниже:
$stream = new VideoStream($filePath); $stream->start();
Вы можете попробовать RTP и RSTP потоковой видеосервер с FFMPEG. PHP-api доступен для FFMPEG, а затем просматривает видео с помощью html5-плеера, как показано здесь .
