line 39: header("Content-Type: video/mp4");
cannot play .webm file format

you should add:

$ext = strtolower(pathinfo($this->path, PATHINFO_EXTENSION));
switch ($ext)
{
case "mp4":
header("Content-Type: video/mp4");
break;
case "webm":
header("Content-Type: video/webm");
break;
}

I play only 40 second of video?

Why?

Very useful. Thank you.

Very nice! solved my problems :)

May be an idea to add a if(connection_aborted()) near line 104 or as part of the while().

all type video formats are not supported in this code... so please any body help me for all types of video supported streaming code..

Very nice! But The user reload video when streaming ...

too much helpful ,thanks alot.....

How to use the code & where to replace the video path plzz let me know

@ranacseruet
works great !!
do you have the same thing for players like VLC and DivX ?

Thank you!

@ranacseruet Thanks for this script! I just noticed that video streaming with this does not work on Android 5 and 6 devices... Any ideas?

Thank you, very nice solution

Very nice class !
But the url with http doesn't work :
$stream = new VideoStream(".http://www.exemple.com/video.mp4");
i need a help.
thanks

@ranacseruet It's possible to stream multiple video files in one php script?

$stream1 = new VideoStream($file1);
$stream1->start();

$stream2 = new VideoStream($file2);
$stream2->start();

If I try the following code, the script is just serving the first video file. Of course I removed the exit's in the class

@annopnod Why are you making an extra variable?

Turn this:
$ext = strtolower(pathinfo($this->path, PATHINFO_EXTENSION)); switch ($ext) { etc etc

Into this:
switch (strtolower(pathinfo($this->path, PATHINFO_EXTENSION))) { etc etc

You are never going to use $ext again. No point in adding variables that are not going to be used.

EDIT: A better way you could do this, is use an array. Line 39 with the Content-Type header can be turned into a "one-liner".

I added on line 16, the video formats allowed for html(could be more than listed):
private $videoFormats = array("mp4"=>"video/mp4", "webm"=>"video/webm", "ogg"=>"video/ogg");

On line 39 or the Content-Type line I replaced-
This: header("Content-Type: video/mp4");
With this: header("Content-Type: ".($this->videoFormats[strtolower(pathinfo($this->path, PATHINFO_EXTENSION))]));

I would like to use this code in a GNU GPLv3 licensed project. Can you please license this code as GNU GPLv3 ?

Hello,

how to use this class in codeigniter? I tried but I didn't response.

Regards
Gokhan

This basically just saved my life. Thank you.

Hello,

This is a really awesome class you've done here. But I am asking myself if there is a way to find when the video ends streaming ? Thank you a lot.

Hello,

the seeking don't working on chrome.

I think you need to change line 48 :
header("Accept-Ranges: 0-".$this->end);
by
header("Accept-Ranges: bytes 0-".$this->end);

Hi. Add this statement in stream method before while: session_write_close(). Without it, the browser freezes when a file is streaming when you make new requests, like click to go to another page for example. Before I use session_write_close(), a new request only worked in Firefox. In another browsers all new requests make browser keeps loading until the stream finishes.

If you're using PHP5+

remove Line 76 (fseek($this->stream, $this->start);)

Line 109 change to $data = @stream_get_contents($this->stream, $bytesToRead, $i);

tested on Chrome, Safari and FF

Is there an option to stream multiple video files one after the other, like it is for audio files?

Hello guys. I had same error in IE11. To solve this issue you need add header("Accept-Ranges: bytes"); after 83 string.
This header is important for IE browsers.

It only plays 2 - 4 seconds of the video on both desktop and iphone. But seems to still download the file.

I have used the above code in my website. When i refresh the page again and again then video play from starting, this is not a video live streaming. How to implement the video live streaming please tell me?

I don't understand what the point of this is. Perhaps I am missing something. However, rather than using all this heavy machinery to display a video, why not just put the path to the video into the src of the html video element?

@ImSeaWorld
Couldn't you use this mime_content_type($this->path) to get the MIME content type header dynamically?

header("Content-Type: ".mime_content_type($this->path));

Thank you that was so helpfull

My Video is 285 MB. I am trying to play using video streaming from aws server. It is playing directly on aws s3 server. But not able to play directly from video streaming.

Hello I want to load subtitles in it. how can I do it?
I used to load subtitles like this

could you please help me to how would I use this line in your code?

Will this script stop streaming if close the player? I have a suspicion that it will output the data until the end of file is reached. Am I correct?

regards

Thank you that was so helpfull, but it's possible to play the video in a <\video> element ?

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)
