hex = 33 hex). Winamp and Windows Media Player cannot play the unmodified .avi file because the non-standard file header corrupts the file. However, Media Player Classic, MPlayer, the VLC Media Player and GOM Player will play the unmodified .avi file, and the Google .mp4 file. Media Player Classic can do so only if an MPEG-4 DirectShow Filter, such as ffdshow, is installed. Most Linux media players (including xine, Totem, the Linux version of VLC Media Player, and Kaffeine) have no problem playing Google's .avi format. An mp4 video file will play in Winamp 5 if an MPEG-4/H.264 DirectShow Filter such as ffdshow and an MP4 Splitter such as Haali are installed, and the extension ;MP4 is added to the Extension List in the Winamp DirectShow decoder configuration. In the spring of 2008, the option to download files in .AVI format was removed. Files were henceforth only available as Flash video or .MP4 video. The same videos, when accessed through the companion YouTube.com site, were available only in Flash video format. Third-party download services Google offered users the means to save only some of the videos on the site, mostly for copyright reasons. Their documentation went so far as to claim that only these videos could be downloaded. However, since viewing a video requires downloading it to the computer, their software merely made saving videos less than trivially difficult, not impossible: a number of solutions, including external software and bookmarklets, have been developed. Market adoption Despite downloading being available in multiple formats, being less restrictive on video uploads, and Google being tremendously well-known, Google Videos had only a minor share from the online video market, amassing around 2.5 million videos uploaded. While initially only available in the United States, over time Google Videos had become available to users in more countries and could be accessed from many other countries, including the United Kingdom, France, Germany, Italy, Canada and Japan. Regardless of general availability, content providers were given the opportunity to limit access to video files to only users from certain countries of residence. However, methods of circumventing geographical filtering existed. Shutdown On October 9, 2006, Google bought former competitor YouTube. Google announced on June 13, 2007, that the Google Video search results would begin to include videos discovered by their web crawlers on other hosting services, in YouTube and user uploads. Thereafter, search result links opened a frameset with a
