FFDShow MPEG-4 Video Decoder 2007.05.17

Program, MPEG-2 biçimindeki DVD, SVCD biçimindeki video dosyalarinizin kodunu çözerek bilgisayarinizda oynatilmasini saglar. Içindeki ekran görüntü süzgeci sayesinde görüntüyü netlestirir ve ses filtresi ile ses kalitesini artirir. Ayrica program Windows Media Player'i da destekliyor.

FFDSHOW is a DirectShow decoding filter for decompressing DivX, XviD, H.264, FLV1, WMV, MPEG-1 and MPEG-2, MPEG-4 movies. It uses libavcodec from ffmpeg project for video decompression, 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.

Notes about latest versions of FFDShow MPEG-4 Video Decoder :

- FFDShow 2007-05-18 (rev. 1180) was compiled by drevil_xxl using GCC 4.1.1 (libavcodec.dll & libmplayer.dll), FFDShow 2007-05-17 (rev. 1177) MMX* was compiled by clsid using ICL9 while FFDShow 2007-05-12 (rev. 1155) 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. 1150 to FFDShow rev. 1167 :

- Small fix for 1164.
- ffmpeg 9017
- 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.
- WEB content: Added favicon to German pages.
- updated libavcodec. fix libmplayer compilation.
- Minor fix.
- updated libavcodec
- updated project files
- New icons by l33twannabe. default for all OS.
On Windows 2000 or older, 4bit icons are used for task bar notification area (aka task tray). If you prefer the classic icon, you can configure using "Tray, dialog & paths" dialog page.
- x64 fixes.
- remove SetThreadIdealProcessor (queue related code).

Important Note :

- Some antivirus software -like AVG- may "detect" a trojan in FFDShow builds. This is a false positive, there are no trojans in FFDShow builds!
