FFDShow MPEG-4 Video Decoder 20070728 rev.1376

FFDShow是一个支持DivX, XviD, H.264, FLV1, WMV, MPEG-1 and MPEG-2, MPEG-4等等的全能解码、编码器,占CPU资源比较少,还有很多画面优化功能,让音频和视频播放更流畅.是播放DVD影片必备的工具!
FFDShow 可以称得上是全能的解码、编码器.最初FFDShow只是mpeg视频解码器,不过现在他能做到的远不止于此.它能够解码的视频格式已经远远超出了 mepg4的范围,包括indeo video,WMV,mpeg2等等.同时,它也提供了丰富的加工处理选项,可以锐化画面,调节画面的亮度等等.不止是视频,FFDShow现在同样可以解码音频,AC3,MP3等音频格式都可支持.并且可以外挂Winamp的DSP插件,来改善听觉效果.可以说现在的FFDShow已经是Windows 平台多媒体播放的非常出色的工具了.

- 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
