Features of ffvfw 20031028
- various compression methods: MPEG 4 compatible (Xvid, DivX 4, DivX 5) using libavcodec or XviD; Divx 3 compatible, MSMPEG4v2, MSMPEG4v1; WMV1/7, WMV2/8; H263, H263+; HuffYUV in YV12 colorspace; MJPEG; MPEG 1; Theora (not for regular use, format isn't stabilized yet); MPEG 2 by using mpeg2enc code from MJPEGtools project; all Windows Media Video 9 supported encoders with output to asf/wmv file or AVI
- all common encoding modes: constant bitrate, fixed quantizer, fixed quality, two pass encoding (depends on compressor features)
- for libavcodec and XviD detailed selection of motion estimation method
- minimum and maximum I frames interval
- minimum and maximum quantizer selection, quantizer type and trellis quantization selection for libavcodec
- adaptive quantization (aka. masking) for libavcodec and XviD, single coefficient elimination
- selectable compression of starting and ending credits
- two curve compression algorithms for second pass of two pass encoding - thanks to XviD developers
- second pass simulation: although not very precise, still helpful for tweaking advanced curve compression parameters
- ability to use libavcodec internal two pass code
- image preprocessing with ffdshow image filters (latest ffdshow version must be installed)
- graph during encoding: if your encoding program doesn't provide one
- B frames support: from one to eight consecutive B frames
- support for MPEG 4 quarterpel and GMC
- selectable interlaced encoding

I was trying for hours to get virtualdub 32bit to load mpeg4 videos.
I installed and uninstalled numerous versions of ffdshow, tried pasting the plugin from ffdshow directory to the plugins directory of vd, tried playing with the options, enabling virtualdub etc, but no success.
The ffdshow codec would not load. Then I installed this one and it worked straight away. So for those who commented that ffdshow is the sane choice, they should think again.

There seems to be some confusion as to what ffvfw actually is. First of all, this build is outdated. ffvfw is now bundled along with ffdshow (which is MUCH more than an MPEG-4 decoder) and any sane person should just get a recent build of ffdshow if they require ffvfw functionality.
For history's sake, ffvfw was a vfw (Video For Windows) interface for the ffmpeg (or a subset of) ENcoder set. it isn't meant to decode. certain programs expect a VFW interface (VirtualDub for instance) and this allowed the ffmpeg set of encoders to be used with these programs.
Again, if you require this functionality, get ffdshow. Be warned though at the time of this writing the recend builds actually won't allow you to encode xvid or x264 as it was deemed to unstable/moving target. ffshow project is recommending people use standalone xvid or x264 to encode. if you can't be bothered, find a ffdshow that was built circa Feb 2011 or so (i believe, double check for yourself)
Long winded, but there it is.
Enjoy ffdshow, folks!

Installed it and couldnt get it to decode MSMPEG42 so I uninstalled it, while uninstalling it put a file called WININIT.INI in the Windows folder that Spybot says is a piece of Malware called Freshbind. Maybe it was a false alarm but I wont install it again.
Latest unofficial versions also supports other compressions like WMW, MPEG1, MPEG2.
