软件介绍：
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。
Key Features :
- 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
- decompression
ChangeLogs:
- added msvc71 build of ffSpkCfg.dll
- compilation fix for rev671
- (ffmpeg 6094,6095,6118,7256)
- Overlay control page : Update the dialog when initial values are set.
- lavc is at major version 51, delete old stuff
- Warpsharp : select "ffdshow original warpsharp" by default.
- adding patch "Do not reconnect with some filter" by eyeperfect.
- updated IS script
- exclude PowerDVD7 from direct show video decoders, because
1: it crashes for drevil_xxl if raw video is enabled.
2: when I play files, the video screen is black.
- ffdshow vfw decoders work for PowerDVD7 instead of direct show decoder.
- Bug fix : Applications were excluded from audio and vfw if they were blacklisted for direct show video decoders.
- "Overlay control" did not work properly for new users
- Wording fix in German IS translation.
- ported delvcr80.nsi to InnoSetup code
- Replaced gcc builds of kerneldeint and tomsmocomp with icl9 builds.
- Added ICL9 project files for kerneldeint and tomsmocomp.
- Modified makefiles for GCC. Now by default SSE/SSE2 instructions will not be used. Usage of SSE/SSE2 can be enabled via "make SSE=yes SSE2=yes". There are some exceptions that always have SSE enabled because they refuse to compile without it. The exceptions are: ffdshow.ax liba52 libmpeg2 libtheora kerneldeint tomsmocomp.
- Add h.263 (not h.263+) to pp list, as it has no inloop.
- updated Russian translation for InnoSetup
- exclude oblivion.exe and morrowind.exe regardless of the setting.
- minor libDTS fix
- removed some unused code
- updated IS script
- added gcc compilations of kerneldeint and tomsmocomp
- Bug fix : Subtitle was sometimes crashing if scaled subtitle height is odd number.
- alphabetic reordering of libavcodec makefile
- some ffmpeg updates
- Move BE_*/LE_*/ST*/LD* macros to a common place. Some further optimization/cleanup would be desirable (e.g. LE_* and LD* should be the same on x86).
