K-Lite Codec Pack 3.2.0 : 64-bit

This is a bundle of 64-bit DirectShow filters that can be used together with 64-bit players, such as Windows Media Center. This pack can co-exist without problems with the regular (32-bit) K-Lite Codec Pack.

The 64-bit versions of Windows can run 32-bit software perfectly fine. So it is recommended to use the regular K-Lite Codec Pack when possible. That one contains more, better and faster decoders. You only need 64-bit filters for use with 64-bit applications.

All RealMedia formats (.ra .rm .rmvb .ram .rpm .rv .rp .rt .rnx .smi .smil etc.) are supported, including streaming content and RealMedia content that is embedded in webpages.

Some advantages compared to RealPlayer:
* Quick and easy install
* It’s easy to make an unattended installation
* Proper uninstallation
* No background processes
* Use a player of your own choice
* Low on resources
* No advertising, no registration forms, nothing annoying

Limitations:
* .smi and .smil files only play the first part of a clip. This is only a problem when the clip consists of multiple parts. These files are not very common. These files do play correctly when embedded in a browser.
* The RealMedia DirectShow splitter does not work with streaming content. You must use the included Media Player Classic to play streaming content.

CodecInstaller is a Windows program that detects the Audio and Video codecs installed on your system, analyzes files to understand which codecs they require and suggests you to install them.

This program can be used to analyze files: it supports avi, mpeg, wmv, wma, ogg, flac, mpc, mp3, mp4, wav, wx and will show technical data such as width/height and ratio, length, video codec, framerate, size, bitrate, total frames, quality factor and metadata such as title, album, year (if available).

CodecInstaller can also be used to distribute video files on a CD, to be sure that who receives the CD will have all the necessary codecs installed: with a single tool he will be able to check if the codecs are already installed and up-to-date. CodecInstaller contains a MovieLauncher that displays informations about the distributed video file (author, plot, director…) along with a screenshot and a ‘Play’ button.
