我将视频存储在Web根部之外,并根据要求将其流式传输。它在Firefox和Chrome中完美工作 - 但在IE,Safari(Mac)和iPad中失败。IE报告Error: Unsupported video type or file path
提出的请求是这样的:
<video width="600" height="300">
<source src="http://myserver.com/getVideo?key=<somehash>&file=video.mp4 type="video/mp4">
</video>`
但是,如果我直接调用视频(不流式传输,并且位置在Web根中),则可以在每个浏览器中工作,如预期。我相信这与我流媒体的方式有关。有什么想法吗?
public function actionGetvideo(){
$filename = $_GET['file'];
$filepath = $_GET['path'];
if ($_GET['k'] != $this->gen_access_key($filename)) {
throw new CHttpException(403, "unauthorized 1");
exit('access key fail');
}
$filepath = '/home/columbin/' . $filepath . $filename;
if (!file_exists($filepath)) {
throw new CHttpException(404, "This video does not exist");
exit('file does not exist');
}
$content_type = 'video/mp4';
$filesize = filesize($filepath);
$fp = fopen($filepath, 'r');
if (!$fp) exit('no file');
$content_length = $filesize;
header('Content-Type: '.$content_type);
header('Content-length: '.filesize($full_request_path));
ob_clean();
flush();
$this->readfile_chunked($filepath);
}
protected function readfile_chunked($filename,$retbytes=true) {
$chunksize = 1*(1024*1024); // how many bytes per chunk
$buffer = '';
$cnt =0;
$handle = fopen($filename, 'rb');
if ($handle === false) {
return false;
}
while (!feof($handle)) {
$buffer = fread($handle, $chunksize);
echo $buffer;
ob_flush();
flush();
if ($retbytes) {
$cnt += strlen($buffer);
}
}
$status = fclose($handle);
if ($retbytes && $status) {
return $cnt; // return num. bytes delivered like readfile() does.
}
return $status;
}
我想我找到了一个解决方案:
我相信您的问题与无法正确设置的标头有关。看看第二个答案。希望它有效。
