Unable to pass node ID to media browser view

I had exactly the same problem.... I wanted to achieve the same result.
The workaround is painful.
I managed to change the URL of the IFRAME into

/media/browser?nid=5574&render=....

and use it as an input for the view, but it's really a hacky solution. It would be nice for Media module pop-up to automatically get those info from the calling page. In general, anyway, I would say that the IFRAME solution is not a good idea, I would prefer a full AJAX pop-up completely managed by the calling page. If there's an error, for example, I end up with a pop-up that I can't close containing another drupal page.... Not ideal.

After page load, I run this:

       if ($("body.page-node").size() < 1) return;
       var url = Drupal.settings.media.browserUrl;
       var i = url.indexOf("?"); 

       var nid = document.body.className.match(/(page-node-)(\d+)/)[2];
       if (!$.isNumeric(nid)) return;
       // use query string "?" and not "/" or you break Media Pop-up at last screen
       Drupal.settings.media.browserUrl = url.slice(0,i+1) + "nid="+ nid + "&" + url.slice(i+1);

@James Tipler
yes this code goes into a js file that you need to run every time a page is loaded.
In my case I have it in a file with other scripts. You can have it alone if you want, but the TIME of execution (or better the ORDER of execution) is important because you need to make sure that the code generating Drupal.settings.media.browserUrl has run before this script.
If it does not work for you it may be for this reason. What I usually do I put all my code related to changing UI things into a single module and I give the module a very high weight at install time, so I'm sure it runs AFTER any other module:

/**
 * Implements hook_enable()
 * to set module weight: higher weight gets executed after other modules, so it can post-process their output
 */
function mymodule_ui_enable() {
	db_update('system') -> fields(array('weight' => 1000)) -> condition('type', 'module') -> condition('name', 'mymodule_ui') -> execute();
}

(I don't remember where I found this example but it works with D7)
In this case my JS is in a js file that is part of this "mymodule_ui" module.

/**
 * Implements hook_init().
 *
 * load essential JS script
 *
 */
function mymodule_ui_init() {
	drupal_add_js(drupal_get_path('module', 'mymodule_ui') . '/js/scripts.js');
}

/js/scripts.js contains:

(function($) {
    // here you may have other unrelated stuff
   //

    //Media pop up handling
    $(function(){
      // pass NID of current page to Media Browser Pop-up
      try {
       if ($("body.page-node").size() < 1) return;
       var url = Drupal.settings.media.browserUrl;
       var i = url.indexOf("?"); 

       var nid = document.body.className.match(/(page-node-)(\d+)/)[2];
       if (!$.isNumeric(nid)) return;
       // use query string "?" and not "/" or you break Media Pop-up at last screen
       Drupal.settings.media.browserUrl = url.slice(0,i+1) + "nid="+ nid + "&" + url.slice(i+1);
       
       
       
      } catch(err) {

      }
    });

})(jQuery);

What did you use for the view contextual filter to get this to work? I was able to get the js script to rewrite the iframe URL.

Ok, for anyone who runs across this. Here is what I used in the view contextual filter, along with the module code from #4.

$nids = $_SERVER ['REQUEST_URI'];
$parts = parse_url($nids);
parse_str($parts['query'], $query);
return $query['nid'];

@smd_ksu I did something similar:

if (!empty($_GET["nid"])) {
return $_GET["nid"];
} else {
return 0;
}

it is somehow needed, to avoid getting errors when the NID is not specified (for example: a new node).

Created a simple module that adds a new Argument Default Views Plugin that uses HTTP_REFERER to retrieve the Node ID.

https://www.drupal.org/project/views_plugin_argument_default_referer

#7 set me on the right path to acquiring node ids, organic group ids, etc. Except I used $_SERVER['HTTP_REFERER'] instead of $_SERVER ['REQUEST_URI'], thank you @smd_ksu and @Jan van Diepen for sending me in the right direction.

Recent versions of media have resolved most of peoples concerns and is compatible with entity translation, multilingual and various advanced configurations. Due to the high volume of inactive and most often irrelevant issues we are Closing this as (outdated).
