Question

Let's say I have a video on a remote server and this its url
"http://domain/video-path/video.mp4"
What is the correct way to stream this video using php with seekable..
I know how to stream the video using fopen and fread but it can't seek with remote file

Answer 1

I'm using this, working both local & external video, seekable & resumable
ini_set('max_execution_time', 0);
$useragent = "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.96 Safari/537.36";
$v = $_GET['url'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 222222);

curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$info = curl_exec($ch);
$size2 = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
header("Content-Type: video/mp4");
$filesize = $size2;
$offset = 0;
$length = $filesize;
if (isset($_SERVER['HTTP_RANGE'])) {
$partialContent = "true";
preg_match('/bytes=(\d+)-(\d+)?/', $_SERVER['HTTP_RANGE'], $matches);
$offset = intval($matches[1]);
$length = $size2 - $offset - 1;
} else {
$partialContent = "false";
}
if ($partialContent == "true") {

header("Content-length: ".$length); // added
} else {

header("Content-length: ".$size2); // added
}
// header("Content-length: ".$size2); // removed
$ch = curl_init();
if (isset($_SERVER['HTTP_RANGE'])) {
// if the HTTP_RANGE header is set we're dealing with partial content
$partialContent = true;
// find the requested range
// this might be too simplistic, apparently the client can request
// multiple ranges, which can become pretty complex, so ignore it for now
preg_match('/bytes=(\d+)-(\d+)?/', $_SERVER['HTTP_RANGE'], $matches);
$offset = intval($matches[1]);
$length = $filesize - $offset - 1;
$headers = array(

curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_exec($ch);

Answer 2

After the other answers on this hadn't been working for me, I've finally found (after much tweaking) a new solution to this which is working for remote/local files.
<?php
$file = 'https://yourfilelocation';
$head = array_change_key_case(get_headers($file, TRUE));
$size = $head['content-length']; // because filesize() won't work remotely
header('Content-Type: video/mp4');
header('Accept-Ranges: bytes');
header('Content-Disposition: inline');
header('Content-Length:'.$size);
readfile($file);
exit;
?>
This allows tracking etc. too, enjoy!
