Here is a quick list of links to useful x64 codecs and related utilities that are compatible with Windows 7 x64 (64-Bit) edition…
- Haali Media Splitter
- ffdshow tryouts (look for the _x64 build under “newest files”)
- Graph Studio
- MediaInfo (select the 64 bit GUI with installer)
- MediaPlayer Classic HomeCinema & Standalone Codecs (the main video codec is MPCVideoDec)
- Xiph Codecs for ogg, speex, theora and flac
There are some issues uninstalling Haali — see the article on how to manually unregister it.
There are also some issues with the Xiph codecs — see the article about that.
