x264 MPEG-4 Video Codec 2200 | 6.07 Mb
The code is written from scratch by Laurent Aimar, Loren Merritt, Eric Petit(OS X), Min Chen (vfw/asm), Justin Clay(vfw), Christian Heine (asm), and Alex Izvorski (asm). To decode, we suggest you to use a recent build of FFDShow, DivX H.264 Decoder or a media player that supports H.264 internally - like MPlayer (there are few interesting frontends for Windows: MPlayerUI, MPlayer Frontend), VLC (VideoLAN Client), KMPlayer, etc.
Important:
- VFW and installer were removed from auto update, VFW is outdated. However, you may try the Leiming's x264 GUI.
- Microsoft .NET Framework 2.0, AVISynth and DGIndex are required to use with MeGUI but NOT included.
