| According to an ffdshow developer, the latest beta of Windows 7 blocks the usage of third party video decoders from Windows Media Player & MCE. |
The ffdshow developer Damien Bain-Thouverez did post his observations, regardings Windows 7 codec support at the Corecodec forum. He reports:
- Microsoft has locked mpeg4 and h264 codecs into Media Foundation, the replacer of DirectShow (even if directshow is still supported).
- There is no way to override those codecs, even if you develop a Media Foundation version of your decoder, because Microsoft maintains a list of preferred codecs (their codecs) into the registry (HKEY_CLASSES_ROOT and HKLM \MediaFoundation\Transforms\Preferred), and this registry key cannot be modified, even in admin mode. Only TrustedInstaller user can modify it, which is FYI the user that protects system files & it cannot be used.
- I have done my tests on build 7057 which is close to release candidate, so few chances that things are going to change till release version.
So, if you are using MediaCenter (MCE 2005, or Vista) already there is appearantly no reason to upgrade to Windows 7.
