FFDShow
FFDSHOW is a DirectShow decoding filter for decompressing DivX, XviD, WMV, MPEG-1 and MPEG-2 movies. It uses libavcodec from ffmpeg project for video decompression, postprocessing code from mplayer to enhance visual quality of low bitrate movies, and is based on original DirectShow filter from XviD, which is GPL'ed edu cational implementation of MPEG4 encoder.
Notes: - This build should fix Windows XP explorer crashes.
- Three editions are available: special for SSE and SSE2 capable CPUs and generic for all others.
SSE a SSE2 build were compiled using Intel C++ Compiler 8.1, generic build was compiled with Microsoft VC6.
Known bug: - in SSE and SSE2 builds Avisynth image processing filter in ffdshow isn't working.
- Subtitles correction may not work correctly in all cases (but should not crash).
These feature was ported from SubRip and if SubRip will give different resulf for a given subtitles, please send them to me.

This is the latest version of the codec DivX 5 ! The best and the most used codec in the world ! You need to install this software if you want to encode a divx5 movie or if you want to see a MPEG 4 movie. You can now select between two different versions of divx video: divx and divx Pro. divx remains free, as always, and you can download it for no cost below. divx Pro is our professional-level product, but personal users may purchase DivX Pro for $19.99. And if you`re willing to watch an occasional pop-up ad while you browse the web, you can download an ad-supported version of divx Pro for no cost at all. We wanted to find a way to make divx Pro available for no cost to all personal users, and this seemed like a good way to do it.
By default, we`re giving you the version with the most features for the lowest cost, which is the ad-supported version. Be sure to change your choice below if you want to download something different. Download codec url:
