The following code correctly displays/plays images, video, and audio in chrome 33 when compiled with dart2js.

In Dartium 31 images and video work, but audio files do not load.

Tested on Ubuntu.

import 'dart:html';

void main() {
  document.body.append(new FileUploadInputElement()
    ..text = 'Open'
    ..onChange.listen(open));
}

void open(event) {
  FileUploadInputElement element = event.target;
  if (element.files.isNotEmpty) {
    var file = element.files.first;
    var url = Url.createObjectUrl(file);

    if (file.type.startsWith('image'))
      document.body.append(new ImageElement(src: url, width: 100));

    else if (file.type.startsWith('video'))
      document.body.append(new VideoElement()
        ..src = url
        ..controls = true);

    else if (file.type.startsWith('audio'))
      document.body.append(new AudioElement()
        ..src = url
        ..controls = true);

    else
      document.body.append(new Text('Unsupported file type: ${file.type}'));
  }
}
