Thank you for this script
I am looking for a solution to can start and stop de streaming like I would decide.
If I have a video of 50s and I would see a piece of this video
For example between the 30de second and de 33de second.
Can somebody my help please ?
Thank you
Alain

A while ago, I was looking for a stream server. I really did try to find a solution for that, to no avail.

Lo and behold, today it occurred to me that "may be" there was a script available that would cover my needs. So, I did search for one first in PHP (I can handle python, but I'm a lot more proficient in PHP) and I found this.

I gotta say, man. What a surprise.

This one works flawlessly, and covered completely my needs (that happen to be quite special).

Dude, I'm incredible grateful for this.

Dear Ranacseruet

If the streaming starts i cannot leave the page until the video has loaded completely. Is there a way to stop the streaming if a visitor wants to leave the page ? (It happens in chrome, in firefox you can leave the page)

Very useful. Thank you.

how did you use that ?
I have this script in a folder name "live" .
So when I open it -> 127.0.0.1/live , it does not show anything !
where should I put video ?
my video is in that folder too .
Please help me !

1- Download the DownloadStream.php
2- Save it in the root of your server (online or local)
3- Create a second file and name it "index.php"
4- Copy the following code in your "index.php"
<?php include "VideoStream.php"; $filePath = "demo.mp4"; $stream = new VideoStream($filePath); $stream->start();

5- Copy and paste the video you would like to stream in the same root (same location as your VideoStream and index files)
6- Rename the video file to be "demo.mp4"

I'm having some issues.
Allowed memory size of 134217728 bytes exhausted (tried to allocate 307971432 bytes)
I have already increased the memory_limit parameter, but it still does not work....

Can someone put an example on how to stream aws S3 video using this VideoStreamer class?

I am using the <video> tag (only test chrome so far) and my videos keep getting stuck "buffering" randomly starting around 40s up to 3 minutes. My sample video isn't much longer. I've never been able to finish watching a video. Manual seeking works (in general and when stuck buffering) but if I try to watch it straight through it always gets stuck buffering.

hi, I'm using your code, I made just a little mod. It work very well on windows (all browser), but in MACOS (all browser) the video does not play. any idea? thanks

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.
