C’EST QUOI FFDSHOW
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
- MJPEG
- 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
