Detecting Pepper (PPAPI) Flash with Javascript

Question

We are using a proprietary document viewer which doesn\'t play terribly nice with the Pepper version of Flash found in some flavors of Chrome, so I\'d like to be able to detect

Answer 1

I made a cleaner version of this method using regexp. Includes tests.

>>> Currently Running Pepper? true

>>> Test Case Plugin Matched? pepflashplayer.dll : true

>>> Test Case Plugin Matched? PepperFlashPlayer.plugin : true

>>> Test Case Plugin Matched? libpepflashplayer.so : true

/**
 * Regular expression to test for pepper PPAPI plugins
 */
var PPAPI_REGEX = /^(lib)?pep(per)?flashplayer/i;

/**
 * Returns true if the current agent is running PPAPI version of flash
 */
function runningPepperFlash() {
  if (navigator.plugins) {
    for (var i = 0, count = navigator.plugins.length; i < count; i++) {
      var plugin = navigator.plugins[i].filename;
      var has_pepper = PPAPI_REGEX.test(plugin);
      if (has_pepper) {
        return true;
      }
    }
    return false;
  }
}

// ----------------------------------------------------------
// test cases:

/**
 * Test case against the three (3) known plugin file types (win,mac,linux)
 */
function executeTestCases() {
  var plugins = ['pepflashplayer.dll', 'PepperFlashPlayer.plugin', 'libpepflashplayer.so'];
  for (var i = 0; i < plugins.length; i++) {
    var has_pepper = PPAPI_REGEX.test(plugins[i]);
    console.log('Test Case Plugin Matched? ', plugins[i], ': ', has_pepper);
  }

}

console.log('Currently Running Pepper?', runningPepperFlash());

executeTestCases();​
