Cannot play video on IE and Firefox with PHP header and readfile/fopen -


i'm using code gets file server (protected file) , download or view on user. i've got problem on making firefox , ie play html5 video url. code working of chrome. know little messy didn't have time make better.

ob_clean();     @ini_set('error_reporting', e_all & ~ e_notice);     @apache_setenv('no-gzip', 1);     @ini_set('zlib.output_compression', 'off');      $file = $_get["file"];     $finfo = new finfo(fileinfo_mime);     $mime = $finfo->file($file);     $size = filesize($file);     header('content-type: '.$mime);     if(isset($_server['http_range'])){         $ranges = array_map('intval',explode('-', substr($_server['http_range'], 6)));         if(!$ranges[1]){             $ranges[1] = $size - 1;         }         if($ranges[0]>0||$ranges[1]<$size)           header('http/1.0 206 partial content');         else           header('http/1.0 200 ok');         header('accept-ranges: bytes');         header('content-length: ' . ($ranges[1] - $ranges[0]));         header("content-disposition: inline;");         header(sprintf('content-range: bytes %d-%d/%d',$ranges[0],$ranges[1],$size));         header("content-transfer-encoding: binary\n");         header('connection: close');         $f = fopen($file, 'rb');         $chunksize = 8192;         fseek($f, $ranges[0]);         while(true){             if(ftell($f) >= $ranges[1]){                 break;             }             echo fread($f, $chunksize);             @ob_flush();             flush();         }     }     else {         header('content-length: ' . $size);         @readfile($file);         @ob_flush();         flush();     }

and 1 doesn't work chrome works firefox , ie.

$path = $_get["file"];  $size=filesize($path);  $fm=@fopen($path,'rb'); if(!$fm) {   header ("http/1.0 404 not found");   die(); }  $begin=0; $end=$size;  if(isset($_server['http_range'])) {   if(preg_match('/bytes=\h*(\d+)-(\d*)[\d.*]?/i', $_server['http_range'], $matches)) {     $begin=intval($matches[0]);     if(!empty($matches[1])) {       $end=intval($matches[1]);     }   } }  if($begin>0||$end<$size)   header('http/1.0 206 partial content'); else   header('http/1.0 200 ok');  header("content-type: video/mp4"); header('accept-ranges: bytes'); header('content-length:'.($end-$begin)); header("content-disposition: inline;"); header("content-range: bytes $begin-$end/$size"); header("content-transfer-encoding: binary\n"); header('connection: close');  $cur=$begin; fseek($fm,$begin,0);  while(!feof($fm)&&$cur<$end&&(connection_status()==0)) { print fread($fm,min(1024*16,$end-$cur));   $cur+=1024*16;   usleep(1000); } die();

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
