ffDShow est un filtre Direct Show qui permet de lire une multitude de formats vidéos tels que le XviD, Divx, WMV, MPEG-1, MPEG-2, MPEG-4 à partir de n’importe quel player vidéo sauf WMP. ffDShow permet d’amélioration de la qualité vidéo, lire les sous-titres, capturer des images ou des séquences.


  • MPEG 4 compatible (Xvid, DivX 4, DivX 5) using libavcodec or XviD
  • Divx 3 compatible, MSMPEG4v2
  • WMV1/7, WMV2/8
  • H263, H263+
  • HuffYUV in YV12 colorspace
  • MPEG 1
  • Theora
  • MPEG 2 by using mpeg2enc code from MJPEGtools project and libavcodec
  • all Windows Media Video 9 supported encoders with output to asf/wmv file or AVI
  • H.264 using x264 library
  • 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
  • decompression
  • fast video decompression using optimized MMX, SSE and 3DNow! code
  • support for different codecs: XviD and all DIVX versions
  • additional support for MSMPEG4v1, MSMPEG4v2, MSMPEG4v3 and H263
  • can act as generic postprocessing filter for other decoders like MPEG1 or MPEG2
  • image postprocessing for higher playback quality
  • automatic quality control: automatically reduces postprocessing level when CPU load is high
  • hue, saturation and luminance correction (MMX optimized)
  • two sharpening filters: xsharpen and unsharp mask
  • blur and temporal smoother
  • tray icon with menu and quick access to configuration dialog
  • noising with two selectable algorithms
  • resizing and aspect ratio changing
  • subtitles
