- FFDShow 2007-06-09 (rev. 1262) was compiled by drevil_xxl using GCC 4.1.1 (libavcodec.dll & libmplayer.dll), FFDShow 2007-06-04 (rev. 1245) MMX* was compiled by clsid using ICL9 while FFDShow 2007-05-31 (rev. 1220) SSE** was also compiled by clsid using ICL9.
* Only for CPUs with support for MMX (MultiMedia eXperience) instructions.
** Only for CPUs with support for SSE (Streaming SIMD Extensions) instructions. Check if your CPU has support for SSE or SSE2 instructions using Cpu-Z, a small tool which shows infos about CPU.

First of all, the FFDSHOW consumes way less CPU power than original DivX codecs, even with maximum post-processing. At the same time the post-processing seems to give excellent quality results and allows more configuring than the original DivX 5 codec. It can even automaticly reduce post-processing if your CPU is getting overloaded. The noise filter adds a kind of a rasterising effect to the picture - might be useful in some cases. The alpha version also includes experimental playback for MPEG-1 and MPEG-2 files (such as VCD and SVCD movies), which works pretty damn well. Only problem is that MPEG-2 playback can't play the SVCD clips directly from the CD, but requires the video to be extracted to the HDD by using VCDGear first.

Features of FFDShow MPEG-4 Video Decoder :

- 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+, H264
· 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

Changes from FFDShow rev. 1160 to FFDShow rev. 1185 :

- Minor x64 fix.
- Bug fix: Bug using ffdshowaudio() in ffavisynth.dll
- Undo ffmpeg 8966. This should hopefully fix encoding crash on CPUs with SSE2.
- updated libavcodec
- Setup script : minor fix
- tiny update to innosetup script
- ffmpeg 9039
- Split dialog page "Info & debug"-> "DirectShow control" + "Info & debug". I'm afraid I have broken the translations. Please update.
- Compatibility list
fix " wmenc.exe"->"wmenc.exe"
- SSSE3 assembling requires latest binutils ([Sadece Kayıtlı Kullanıcılar Linkleri Görebilir. Üye Olmak İçin Tıklayın...], not GCC 4.0.4.
- Unicode subtitle bug fix by jh6rooms: Subtitle rendering failed when file contains 0x1a.
[Sadece Kayıtlı Kullanıcılar Linkleri Görebilir. Üye Olmak İçin Tıklayın...]
- Winamp plugin "Allow multichannel audio processing"
Bug fix: mixed stream with stereo and multichannel.
- msvc compilation fix
- Small fix for 1164.
- Updated project files. If you have trouble compiling, then remove "VISTA_SPDIF" from the Preprocessor Definitions. That requires Windows SDK 6.0 (or 5.2 with library 'Uuid.Lib' from 6.0).
- Enable some SSSE3 code. It should only get used if your CPU supports it. Please test both decoding and encoding.
- updated uClibc++
- Minor msvc libavcodec fix.
- Use DECLARE_ALIGNED from mem.h (which is included through common.h).
- Some msvc libavcodec fixes.
- Added xvidcore.dll to rebase list.
- WEB Content: Added "in sync with" comments. Please update them if you make non-internal changes.
