FFDShow MPEG-4 Video Decoder 20090503 Rev2936

FFDShow MPEG-4 Video Decoder 20090503 Rev2936 offers you the DirectShow and VFW codec for decoding/encoding many video and audio formats, including DivX and XviD movies using libavcodec, xvid and other opensourced libraries with a rich set of postprocessing filters.

FFDShow 2009-05-03 (rev. 2936) was compiled by drevil_xxl using GCC 4.1.1 (libavcodec.dll & libmplayer.dll), FFDShow 2009-05-03 (rev. 2936) MMX* was compiled by clsid using ICL9 while FFDShow 2009-04-29 (rev. 2925) 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.

Major Features:

1. 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
2. All common encoding modes: constant bitrate, fixed quantizer, fixed quality, two pass encoding (depends on compressor features)
   
3. For libavcodec and XviD detailed selection of motion estimation method
   
4. Minimum and maximum I frames interval
   
5. Minimum and maximum quantizer selection, quantizer type and trellis quantization selection for libavcodec
   
6. Adaptive quantization (aka. masking) for libavcodec and XviD, single coefficient elimination
   selectable compression of starting and ending credits
   
7. Two curve compression algorithms for second pass of two pass encoding thanks to XviD developers
   
8. Second pass simulation: although not very precise, still helpful for tweaking advanced curve compression parameters
   
9. Ability to use libavcodec internal two pass code
   
10. Image preprocessing with ffdshow image filters (latest ffdshow version must be installed)
    
11. Graph during encoding: if your encoding program doesn't provide one
    
12. B frames support: from one to eight consecutive B frames
    
13. Support for MPEG 4 quarterpel and GMC
    
14. Selectable interlaced encoding
    
15. Decompression
