1. About ffdshow video decoder
ffdshow is a DirectShow decoding filter for decompressing DIVX movies.
It uses libavcodec from FFmpeg project for video decompression and
compression (It can use xvidcore.dll installed with xvid codec, too.),
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 educational implementation of MPEG4 encoder.
2. Features
- fast video decompression using optimized MMX, SSE and 3DNow! code
- support for different codecs: Xvid and all DIVX versions
- support for H.264 and H.264/AVC (Advanced Video Coding)
- additional support for MSMPEG4v1, MSMPEG4v2, MSMPEG4v3 and H.263
- 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
