PHP - Php Stream Mp4, Detect When Client Stops Streaming, Or Disconnects
I am currently streaming my mp4 files perfectly fine using php. My issue is, how do I detect when the video is either no longer being watched, or disconnected? I need to run a function after this so that I know the video is no longer being watched for analytics. Is there a way maybe with sockets or something? I'm currently using this.
if (file_exists($request)) {
$fp = @fopen($request, 'rb');
$size = filesize($request);
$length = $size;
$start = 0;
$end = $size - 1;
header("Content-Type: video/mp4");
header('Accept-Ranges: 0-' . $length);
if (isset($_SERVER['HTTP_RANGE'])) {
$c_start = $start;
$c_end = $end;
list(, $range) = explode('=', $_SERVER['HTTP_RANGE'], 2);
if (strpos($range, ',') !== false) {
header('HTTP/1.1 416 Requested Range Not Satisfiable');
header('Content-Range: bytes ' . $start . '-' . $end . '/' . $size);
exit();
}
if ($range == '-') {
$c_start = $size - substr($range, 1);
}
else {
$range = explode('-', $range);
$c_start = $range[0];
$c_end = (isset($range[1]) && is_numeric($range[1]) ? $range[1] : $size);
}
$c_end = ($end < $c_end ? $end : $c_end);
if (($c_end < $c_start) || (($size - 1) < $c_start) || ($size <= $c_end)) {
header('HTTP/1.1 416 Requested Range Not Satisfiable');
header('Content-Range: bytes ' . $start . '-' . $end . '/' . $size);
exit();
}
$start = $c_start;
$end = $c_end;
$length = ($end - $start) + 1;
fseek($fp, $start);
header('HTTP/1.1 206 Partial Content');
}
header('Content-Range: bytes ' . $start . '-' . $end . '/' . $size);
header('Content-Length: ' . $length);
ob_end_flush();
$buffer = 8192;
$time_start = time();
$bytes_read = 0;
while (!feof($fp) && (($p = ftell($fp)) <= $end)) {
$response = stream_get_line($fp, $buffer);
echo $response;
$bytes_read += strlen($response);
if (30 <= time() - $time_start) {
file_put_contents('/var/www/html/movieCon/'.$user.'_'.$token.'_'.$movie_id.'.con', time());
$time_start = time();
$bytes_read = 0;
}
}
fclose($fp);
exit();
}
Similar TutorialsNonsense question, but still... Is there any method to detect gmail client timezone setting? Like mobile app and web gmail client? Not browser or IP or similar, but gmail. Thank you for your answers. I'm not sure what PHP considers an "aborted connection" and things like that, but the way this chat works is by updating a file and using the timestamp off it to determine if new posts exist. Rather than re-checking the server over and over, this code will check once and keep the connection open until a response is made. The only problem is, it works too well! Even after the tab is closed and I try another script on the site or the same script, it all hangs until I update the file - here is the code snippet: while (($currentmodif <= $lastmodif) && (connection_aborted() == 0) && (connection_status() == 0)){ // check if the data file has been modified usleep(10000); // sleep 10ms to unload the CPU if (connection_aborted ()) break; if (connection_status () != 0) break; clearstatcache(); $currentmodif = filemtime($filename); } I have put several measures in to attempt to break the loop when the user disconnects, but it just doesn't work! It will continue to hang and hang and hang until I re-upload the file $filename HOW CAN I BREAK THE WHILE LOOP WHEN THE MEMBER LEAVES THE PAGE? I could post up an example but its ultimately useless after one load unless you have control over updating the file. Thanks! I wish to create validation rules once which are used both on the client and on the server.
For instance, I will start off with the following PHP object:
stdClass Object
(
[rules] => stdClass Object
(
[email] => stdClass Object
(
[required] => 1
[email] => 1
[remote] => stdClass Object
(
[url] => check-email.php
[type] => post
[data] => stdClass Object
(
[username] => function() {return $( '#username' ).val();}
)
)
)
)
[messages] => stdClass Object
(
[email] => stdClass Object
(
[required] => an email is required
)
)
)
When the edit page is downloaded to the client, I will include this object in some format suitable to the client.
The client will then use the jQuery Validation plugin (http://jqueryvalidation.org/) along with the validation object, and client side validate the page.
When the form passes client side validation and is uploaded, PHP will use the same validation object to serverside validate the form (I have this part working as desired).
My question is how should I pass this data to the client? Originally, I would just use PHP to write some JavaScript.
exit('var myObj='.json_encode($myObj));
Note that when I json_encode the object, the value of $myObj->rules->email->remote->data->username is a string with quotes around it, however, I can easily use PHP to strip these tags before sending it to the client.
As Jacques1 pointed out in http://forums.phpfre...ascript-client/, I should never ever use PHP to generate JavaScript, and should use AJAX to download the JSON directly. I tried doing the later, but found that a callback function could not be included in the JSON.
Please advise on the best way to accomplish this.
Thank you
So i have a large video files, 1.5 gigs even. I made an html5 video player where the source is a php file. The php file is supposed to go below the web root and serve the video file to the html5 video tag. This all works just fine if the video using a script that uses HTTP_RANGE to serve the file in parts to the client. The problem is, once one video is playing - i can't do anything else. Its like the server locks up. I mean i can scrub that video, i can do anything to that page. I just can't navigate away. But i can open a new browser and play a new video. But again, once that first one is playing, or even paused, i can't do anything else. That is of course until i restart apache. Any ideas on how to stream these large files better? I have a feeling they are set to stream and never stop. This is the code for that Code: [Select] function rangeDownload($file) { $fp = @fopen($file, 'rb'); $size = filesize($file); // File size $length = $size; // Content length $start = 0; // Start byte $end = $size - 1; // End byte // Now that we've gotten so far without errors we send the accept range header /* At the moment we only support single ranges. * Multiple ranges requires some more work to ensure it works correctly * and comply with the spesifications: http://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html#sec19.2 * * Multirange support annouces itself with: * header('Accept-Ranges: bytes'); * * Multirange content must be sent with multipart/byteranges mediatype, * (mediatype = mimetype) * as well as a boundry header to indicate the various chunks of data. */ header("Accept-Ranges: 0-$length"); // header('Accept-Ranges: bytes'); // multipart/byteranges // http://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html#sec19.2 if (isset($_SERVER['HTTP_RANGE'])) { $c_start = $start; $c_end = $end; // Extract the range string list(, $range) = explode('=', $_SERVER['HTTP_RANGE'], 2); // Make sure the client hasn't sent us a multibyte range if (strpos($range, ',') !== false) { // (?) Shoud this be issued here, or should the first // range be used? Or should the header be ignored and // we output the whole content? header('HTTP/1.1 416 Requested Range Not Satisfiable'); header("Content-Range: bytes $start-$end/$size"); // (?) Echo some info to the client? exit; } // If the range starts with an '-' we start from the beginning // If not, we forward the file pointer // And make sure to get the end byte if spesified if ($range == '-') { // The n-number of the last bytes is requested $c_start = $size - substr($range, 1); } else { $range = explode('-', $range); $c_start = $range[0]; $c_end = (isset($range[1]) && is_numeric($range[1])) ? $range[1] : $size; } /* Check the range and make sure it's treated according to the specs. * http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html */ // End bytes can not be larger than $end. $c_end = ($c_end > $end) ? $end : $c_end; // Validate the requested range and return an error if it's not correct. if ($c_start > $c_end || $c_start > $size - 1 || $c_end >= $size) { header('HTTP/1.1 416 Requested Range Not Satisfiable'); header("Content-Range: bytes $start-$end/$size"); // (?) Echo some info to the client? exit; } $start = $c_start; $end = $c_end; $length = $end - $start + 1; // Calculate new content length fseek($fp, $start); header('HTTP/1.1 206 Partial Content'); } // Notify the client the byte range we'll be outputting header("Content-Range: bytes $start-$end/$size"); header("Content-Length: $length"); // Start buffered download $buffer = 1024 * 8; while(!feof($fp) && ($p = ftell($fp)) <= $end) { if ($p + $buffer > $end) { // In case we're only outputtin a chunk, make sure we don't // read past the length $buffer = $end - $p + 1; } set_time_limit(0); // Reset time limit for big files echo fread($fp, $buffer); flush(); // Free up memory. Otherwise large files will trigger PHP's memory limit. } fclose($fp); } Hi, I've been trying,for a while now, to stream mp3 using MING extension. I have the later XAMPP 1.7.4 installed. So the code goes something like : Code: [Select] <?php $m = new SWFMovie(); $m->setRate(12.0); $m->streamMp3(file_get_contents('a.mp3',"r")); $m->setFrames(1420); header('Content-type: application/x-shockwave-flash'); $m->output(); ?> 'a.mp3' is in the same directory as of the php file. It opens the file, reads the file - but i've no idea what is it doing after that. There are no errors or warnings. A white ' FLASH ' screens comes up. Thats all. I've tried googling this thing up. I didn't find anything. What am I doing wrong? Hi, i am trying to stream a video from Rackspace clould files account. I could simply get the url of the video file and stream the video using the php api they have provided. But they have provided a stream function which they suggest to be used for video streaming or for large images. Here is the code of the api : /** * Streaming read of Object's data * * Given an open PHP resource (see PHP's fopen() method), fetch the Object's * data and write it to the open resource handle. This is useful for * streaming an Object's content to the browser (videos, images) or for * fetching content to a local file. * * Pass in $hdrs array to set specific custom HTTP headers such as * If-Match, If-None-Match, If-Modified-Since, Range, etc. * * Example: * <code> * # ... authentication/connection/container code excluded * # ... see previous examples * * # Assuming this is a web script to display the README to the * # user's browser: * # * <?php * // grab README from storage system * // * $my_docs = $conn->get_container("documents"); * $doc = $my_docs->get_object("README"); * * // Hand it back to user's browser with appropriate content-type * // * header("Content-Type: " . $doc->content_type); * $output = fopen("php://output", "w"); * $doc->stream($output); # stream object content to PHP's output buffer * fclose($output); * ?> * * # See read() above for a more simple example. * # * </code> * * @param resource $fp open resource for writing data to * @param array $hdrs user-defined headers (Range, If-Match, etc.) * @return string Object's data * @throws InvalidResponseException unexpected response */ function stream(&$fp, $hdrs=array()) { list($status, $reason) = $this->container->cfs_http->get_object_to_stream($this,$fp,$hdrs); #if ($status == 401 && $this->_re_auth()) { # return $this->stream($fp, $hdrs); #} if (($status < 200) || ($status > 299 && $status != 412 && $status != 304)) { throw new InvalidResponseException("Invalid response (".$status."): " .$reason); } return True; } Here is the sample code they shared : $output = fopen("test.jpg", "w"); $pic->stream($output); fclose($output); If i echo the $pic variable, it just contains the name of the file. How do i display the image and how do i use this for streaming a video? Iam very new to php, so kindly help me. Thanks. Hi all, I've been running into some issues trying to stream .mp3 files, specifically Safari/Flash... Firefox works great. I'm about to throw in the towel on this one and try another streaming solution, so I thought I'd reach out and connect with the PHP pros here before trying something else. Basically, the PHP streamer takes a track guid variable and token variable(MD5), looks up the field in the DB, gets the url and then proceeds to stream the file with no caching, and keeping the URL hidden from the user so they can't download it. The token variable is there to assure that the url is only used once. Once it is, the script will not allow the stream if the token/track guid combo already exists in the DB. The problem with the looping is that once that token has been used it won't stream the track, which is how it's suppose to work, sans looping. I've put an MYSQL INSERT into the code to verify that it does loop.. usually I see 3- :wtf:5 consecutive entries in the DB for that token. So Firefox does not do this.. and I gather it's something to do with how the client streams with the "readfile" function. Pasted below is some code to show the headers and the readfile function I am using. I can post the rest of the script if need be. //$path and $tokenApproved are variables i set earlier in the script date_default_timezone_set('GMT'); $date = date(DATE_RFC822); $filesize = ffilesize($path); $shortlen = $filesize - 1; //ffilesize() is a custom filesize function if($tokenApproved) { header("Content-type: audio/mpeg"); header("Content-Length: $filesize"); header('Content-Range: bytes 0-'.$shortlen.'/'.$filesize); header("Expires: $date"); header('Content-Disposition: filename="eztunesaudio.mp3"'); header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); readfile($path); } //eztunesaudio.mp3 is just a default name I give the stream I have a website http://www.pbm-biz.com/cricket/ where I am streaming Live Cricket world cup matches. My question is that during the streaming, I would like to keep the code in PHP so that others don't copy it. I can't find any solution. Any suggestions. Thanks, Faisal I am creating a stream for my website similar to facebook's news feed where users can post to, add photos too ect. When a user uploads a photo it gets added to the photos table and a new row to the stream Code: [Select] mysql_query("INSERT INTO photos VALUES ('','$id','$username','$photo','$time')"); mysql_query("INSERT INTO stream VALUES ('','$id','$username','$time','No comment','$photo','')"); Which displays the image on the stream fine but what i am looking to do is if the user uploads more images one after another instead of adding a new post to the stream for every picture i want to show all of the new pictures in one post like what Facebook does. I can't figure out how i would do this. The following will create a PHP stream. $response = $this->guzzleHttp->get($url); $stream = \GuzzleHttp\Psr7\StreamWrapper::getResource($response->getBody()); How can I return a stream using just PHP's native cURL library? Hi ! I'm trying to understand how php://input works. I've read the manual ( http://php.net/manual/en/wrappers.php.php ) and I have an example of a file upload receiving the file with php://input instead of $_FILES. But I can't understand it, does somebody a good tutorial about php://input ? What is the data inside it? is always the same that $HTTP_RAW_POST_DATA ? How can we send a file to PHP and receive it with php://input ? I'm trying to see what's inside php://input with this code: Code: [Select] $in = fopen("php://input", "rb"); echo Debug::vars($in); if ($in) { while ($buff = fread($in, 4096)) { echo $buff . EOL; // fwrite($out, $buff); } } but I get always blank output (Debug is a Kohana class and it returns: Quote resource(stream) php://input Thanks !! It is not outputting anything after the third echo.

Any help would be appreciated .
Edited by ZohaibKhalid1, 17 October 2014 - 08:41 AM. Hi everybody, I'd like to protect a rtsp stream coming from a videoserver using a php page. Is this possible? The rtsp stream is a live h.264 stream with it's own local ip address. Currently i can access the stream by entering rtsp://192.168.1.3 in the browser and quicktime starts up. I have apache running on a different machine (192.168.1.2), which I want to use to pass on the stream. I'd like the rtsp stream to be accessed by entering rtsp://192.168.1.2/?password=changes-a-lot I've been using headers and readfile a lot to protect files. But the live stream seems to work differently. I've seen a lot of posts on how to access media using rtsp, but none of these work with a live stream. Does anybody have any ideas on how to get this to work? The other day I noticed someone had post something like this, well this was actually the solution to the problem. But it got me thinking about a project of mine that I am working on and the need to pump out a downloadable file. We are storing most of the files in a database using base64 encoding the 2 key types of files we are storing are images and PDF's mostly pdf's anyway where I am wanting to go with this is, is there anyway to take the base64 encoded file and get it to download through this, or am I tackling the idea in the wrong way? <?php $filename = 'somename.txt'; //this would obviously be changed according to the file type we would output $data =<<<DATA I know my data would go here for the given file once decoded. DATA; header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename=' . $filename); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . strlen($data)); echo $data; ?> I am trying to display an image stream from my pond cam... The stream generated by my ip video server is a jpeg stream without boundaries. Causeur of this the normal mime replace isn't working. I need php to read a picture from the stream, and display the picture in the browser while reading the next picture in the background. I've got to the point that I am able to connect to the stream, read the first image, and display it in the browser as can be seen in the link below (cam is only on from 09:00 until 16:00) http://cam.xsiteit.nl/readstream_test.php From this point I need to read the second image and replace the image in the browser with the new one. This process has to continu until the browser is closed. Any help would be great! Regards, Peter How can I decode the following contents?
Thanks a lot.
<html><head><meta http-equiv="Pragma" content="no-cache"/> <meta http-equiv="Expires" content="-1"/> Hi, this is my first post but I hope it's fruitful. First, I am running PHP 5.1.6 on my VPS and I am trying to write a Leaderboard script for a game that takes place on my server. The game was not written by me and I know it works perfectly. I have also accessed the database through shell multiple times, so I know that works fine. Here is the code for my leaderboard script: Code: [Select] <html> <title>Middle Cup Leaderboard</title> <body> <?php echo "about to connect\n"; $dbc = mysqli_connect ('localhost','root', 'password', 'shoddybattle') OR die ('sql error:' . mysqli_connect_error() ); echo "Debugging point: connected\n"; //$query = "SELECT estimate FROM users"; //$result = mysqli_query($dbc,$query) or die ('Could not retrieve ratings!'); //echo 'Debugging point: requested\n'; //mysqli_close($dbc); //echo 'Debugging Point: closed\n'; //echo 'Middle Cup Leaderboard Results\n'; //echo $result; ?> </body> </html> Here is the source code of the output when I navigate to it: Code: [Select] <html> <title>Middle Cup Leaderboard</title> <body> about to connect As you can see, it looks as if the program stops indefinitely when I try to connect to the database. Does anyone know what could be wrong with this? Any help would be greatly appreciated! |
