Freeview: IPTV Live TV Streams

[Parnas]

Please help me for how to use "mount -o bind" specific to this case.

For instance:

Code: Select all

mkdir /tmp/umsp_plugins
cp -a /etc/umsp/plugins/*.php /tmp/umsp_plugins
mount -o bind /tmp/umsp_plugins /etc/umsp/plugins


Then, /etc/umsp/plugins magically becomes writable, as it's now a synonym for /tmp/umsp_plugins, and you can install your own plugins there.
Just remember that /tmp is a temporary area whose contents are not kept across reboots. So, if you're putting your own scripts therein, remember to keep a backup copy in a permanent storage area.

You have to execute these commands after each reboot, so you may want to put them in a shell script for easiness of use.

After some experimetns, I was made some changes to original freeview proxy plugin

# cat http-stream.php

Code: Select all

<?php

function _pluginMain($prmQuery) {
  $items = _pluginCreateChannelList();
  return $items;
}

function _pluginCreateChannelList() {
  $videoItems = array (
     'EuroSport' => 'http://.............:3000/TS/S36.0E-112-5-20506.ts', //<- channel from my first VDR server
     'RBK' => 'http://localhost:4080/udp/225.50.64.1:1234', //<- UDP multicast from my LAN, converted to http stream by udpxy
     'EuroNews'  => 'http://.........:3000/TS/S36.0E-112-6-20611', //<- channel from my second VDR server
     'Premiere'  => 'http://localhost:4080/udp/225.50.65.8:1234', //<- another UDP multicast from my LAN, converted to http stream by udpxy
  );

  foreach ($videoItems as $name => $url) {
    $url_data = array('itemurl' => $url);
    $url_data_string = http_build_query($url_data);

    $retMediaItems[] = array (
      'id' => 'umsp://plugins/http-stream?' . $url,
      'dc:title' => $name,
      'upnp:class' => 'object.item.videoitem',
      'res' => 'http://127.0.0.1/umsp/plugins/http-stream-proxy.php?'.$url_data_string,
      'protocolInfo' => 'http-get:*:*:*',
    );
  }
  return $retMediaItems;
}

?>


after adding content-len & content-size headers channels starts showing a much faster

# cat http-stream-proxy.php

Code: Select all

<?php

$rawURL = $_GET['itemurl'];
$parsedURL = parse_url($rawURL);
$itemHost = $parsedURL['host'];
$itemPath = $parsedURL['path'];
$itemPort = $parsedURL['port'];

_http_streamGet($itemHost, ($itemPath ? $itemPath : "/"), ($itemPort ? $itemPort : 80));

function _http_streamGet($prmHost, $prmPath, $prmPort) {
   # print "host: ".$prmHost."\n";
   # print "port: ".$prmPort."\n";
   # print "path: ".$prmPath."\n";
   
   $fp = fsockopen($prmHost, $prmPort, $errno, $errstr, 30);
   if (!$fp) {
      echo "$errstr ($errno)<br />\n";
   } else {
      $out  = "GET ". $prmPath ." HTTP/1.1" ."\r\n";
      $out .= "User-Agent: Wget/1.12 (elf)" ."\r\n";
      $out .= "Host: " . $prmHost . "\r\n";
      $out .= "Cache-Control: no-cache" ."\r\n";
      $out .= "Connection: Close"."\r\n"."\r\n";
      fwrite($fp, $out);     
      $headerpassed = false;
      while ($headerpassed == false) {
         $line = fgets($fp);
         list($tag, $value) = explode(": ", $line, 2);
         
         if (stristr($tag, 'Location')) {
            $target_url = trim($value);
            $url_data_string = http_build_query(array('itemurl' => $target_url));
            header("Location: http://127.0.0.1/umsp/plugins/http-stream-proxy.php?".$url_data_string);
            continue;
         }
         if (trim($line) == "") {
            $headerpassed = true;
            header("Content-Type: video/mpeg");
            header("Content-Size: 65535");
            header("Content-Length: 65535");
         }
         header($line);
      }
      fpassthru($fp);
      fclose($fp);
   }
}

?>


+ with udpxy program ( http://depositfiles.com/files/tdr1i86oh ) I can watch multicast channels from my LAN

# cat S65updxy

Code: Select all

#!/bin/sh

case "$1" in
  start)
    /bin/udpxy -p 4080

    ;;

  stop)
    killall udpxy
   
    ;;

esac


Unfortunately I cant find a method to disable "start\continue" dialog before every channel ((

Hi mmikel,

I also implemented a plugin for watching live TV from VDR on the wdtv live. You can find my thread here: http://forum.wdlxtv.com/viewtopic.php?f=49&t=517. My plugin includes a channel parser, that shows all channels from your VDR on the wdtv...

BTW, thanks for your proxy code with the faster rendering startup. I adapted my proxy to your method.

Greetings, skyball

Hi Parnas

I cant seem to get your freeview plugin to work. Basically I copied the freeview.php (all the channels show up as folders ) and also copied the freeview-proxy.php to the umsp/plugin folder. I am using the latest EXT firmware from brad (4.2). The video never show up and from a black screen it goes back to the folder view after about 3 seconds from when I press the play button. I also tried to use the update proxy made by mmikel and still not able to get any video playback.

I hope you can give me a hand on this one. Thanks

[monsieur]

I am also facing the same problems as g_krassa. I do get the list of channels but cannot play any of them. Upon trying to play any of the channels (BBC, Discovery, FashionTV, etc etc), I get a blank screen and then it returns to the channel list. Is there any way to debug this on my end? (Look for some message log somewhere). I was successfully able to play the streams using VLC player.

Appreciate your effort and all the help.

[Parnas]

I hope you can give me a hand on this one. Thanks

Hi guys!

If you can't get any channel to play, despite the URL be working in VLC on a desktop PC, as a first debugging step I would check out the php error log in /tmp/php5 for related information.

hi! I'm also having the same problem as g_krassa and monsieur, my php5 error log says this:

Code: Select all

No idea what it means, I'm in way over my head trying this
anyway, interesting project, thanks!

[zoster]

The first error means that the plugin file is missing or has the wrong name.
The second error means that there already was some kind of output (probably an error msg) and that the HTTP headers can't be set anymore.

I was getting "Can not modify header information" error when my .php files were encoded in UTF-8.

[arpanet420]

Whats the "right" encoding? I've tried ISO-8859-1 and WINDOWS-1252 and it still gives me the "Can not modify header information" sorted the " PHP Fatal error" though, thanks zoster!
