Is there a way to use this and prevent users from downloading the video? The video can be downloaded by just right clicking after the entire video has been played. I am looking for a way to prevent it from being downloaded (like streaming services use).

thank you so much
the things I did

add the first line in part setHeader()
session_write_close();

---

line 110
print( $data ) ;

---

Has anyone managed to block downloads?
I made this code, but it only works in chrome and Opera, firefox does not work, anyone to help?

if(isset($_SERVER["HTTP_REFERER"]) && $_SERVER['HTTP_SEC_FETCH_SITE'] == 'same-origin'){
  $filePath ="videos/depoimentos/".$filePath.".mp4";
  if(file_exists($filePath)){
    $stream = new VideoStream($filePath);
    $stream->start();
  }else{
    echo "Error!";
  }
}

Is there some simple changes to use it with http2=http/2=h2 ?

I changed for example

header('HTTP/1.1 416 Requested Range Not Satisfiable');

to

header('', false, 416);

So no HTTP/1.1 in my code...

The class always responsed with a 416...

Never mind now it works maybe some strange caching...

I have an existing Webrtc one2many broadcasting application working. I also have a php based social website that is working. I need to integrate the Webrtc into the social website. Any recommendations how to go about implementing this?

Doesn't work for me when I use the default video player of the browser. In Firefox, it won't change position. In Chrome, it won't enable the player. Your published example, http://demo.codesamplez.com/html5/video, seems to work everywhere because the player doesn't use the library code. It has the video path specified explicitly.

Whta are you try to do??

the code work for me

I gave up on this library and experimented and created my own code that works. I have no idea what the problem was. Thanks anyway. Maybe I didn't understand exactly how and where to use this code.

It's awesome, can you share your code??

It's still under development. It works great, but fails on Safari/MacOS. I am having great difficulty figuring out how to debug it on Safari, which seems to not have Dev Tools. It is an app that asks the user for a password, then provides a list of video files as buttons. Clicking a button plays the file, with repositioning, using the default browser video player. The entire app is a bit lengthy for simply posting, but eventually I can release it as a repository.

Understand, if you need some help, just put here

Working fine for me for small size video file but for big size file I am getting net::ERR_CONTENT_LENGTH_MISMATCH 206 (Partial Content) in chrome console and of course the status is failed in chrome network tab.
Any Help !!!

himadrisaha89, this usually means that the software that is sending the streaming file is either calculating or formatting the size information that it sends to the client player incorrectly. If you look at the network information in a browser developer tool, you might be able to see the problem.

Is it possible for the controls not to be displayed on that page? Or at least not be able to download the video? or do you need a script for that?

This code need UPDATE, he cannot read EXTERNAL URL VIDEO, only local videos, for solve this problem I create a new package that works with laravel, check it out: https://github.com/micilini/video-stream.

My Package can handle local and external video files 👯

I got an error please help

filesize(): stat failed for http://laraveltest.test/ElephantsDream.mp4

got error here. from class VideoStream
$this->size = filesize($this->path);

where code

$a = 'http://laraveltest.test/ElephantsDream.mp4'; // public folder video
$stream = new VideoStream($a);
return response()->stream(function() use ($stream) {
$stream->start();
});

Any help please using laravel 9

trying to access a file using http:// does not look valid to me, probably you want something like one of these:

$a = storage_path('ElephantsDream.mp4');
$a = public_path('ElephantsDream.mp4');
$a = asset('ElephantsDream.mp4');

depending on where the file is physically in your laravel directory.

@carcinocron thanks so external url not supported right ?

Is there a way to do this same process but with AJAX?

Here is my code. For sure require to check URL and File. Just assume file path / URL is correct.
// Check starting string
if (substr($this->path, 0, 3) == 'htt' || substr($this->path, 0, 3) == 'ftp') { /* External URL - allow_url_fopen=On /
$headers = get_headers($this->path, 1);
$this->size = $headers["Content-Length"];
}else{ / Internal file */
$this->size = filesize($this->path);
}
:
//fseek($this->stream, $this->start);
header('HTTP/1.1 206 Partial Content');
header("Content-Length: ".$length);
header("Content-Range: bytes $this->start-$this->end/".$this->size);
// Use stream_get_contents instead of fseek
echo stream_get_contents($this->stream, -1, $this->start);

Hello i need a help
what i get is only the video.mp4 that I moved to the root server

The script worked for me, but forward and backward movement of the video is not supported.

This script is better supports Video of forward and backward movement :
