New information has emerged regarding the web browser for Wii U which will be capable of running on either your television or the Wii U Gamepad screen. You won’t be able to download files or upload files in the browser, so you won’t be able to download and save, or upload videos or pictures. We already know that the browser won’t support Flash, but instead it will support HTML 5 video. AAC codecs are supported for sound, while video formats and codecs include H.264 (MPEG-4 AVC Video) and MP4.
