Ffdshow is a Windows DirectShow filter and VFW codec for many audio & video formats, such as H.264, X.264, DivX & Xvid. Over 60 bugs have been fixed, codecs have been updated, and support for a few new formats has been added in the tryouts. Windows Vista is now also supported.

             Bugs fixed after beta2

• libavcodec encoders did not accept frame rates except 25fps. Other encoders sometimes had inaccurate frame rates.
• If ffdshowaudio() was used in AviSynth script, an error occurred.
• If a Unicode subtitle file contained 0x1a, the rendering failed.
• The image got mirrored if AviSynth filter output in RGB color space.
• If "RAW video" -> "YV12" in VFW decoder was enabled, the image got mirrored when VFW codec was used via DirectShow.
• Improved stability of Winamp plugin handling.
• On the fly resize: If you entered 8 (as the first digit of 800) for the vertical size, it crashed depending on the used method (lanczos tap>=4, spline, etc).
• If resize was being used, changes to the pixel aspect ratio (SAR) of the video were ignored.
• If "Resize & aspect" -> "Borders" -> "Inside" was used, "Keep original aspect ratio" calculated wrong size.
• AviSynth script could not be saved (Unicode builds only).

New features added after beta2

• Deinterlacing support (set interlace flag) for MPEG4-ASP through Xvidcore decoder.
• A dialog is shown when an unknown application (which is neither listed in the blacklist nor in the whitelist) tries to load ffdshow.
• libavcodec encoders pop up error messages.
• The AviSynth filter was updated to give scripts access to more frames than just the current one. Together with the added "3:2 pulldown" settings this allows many of the IVTC, deinterlacing and temporal filters for AviSynth to work properly in ffdshow.
• Updated icons ( ). Classic icons are still available.
• ATRAC3 (Adaptive TRansform Acoustic Coding, compressed audio format) has been added.
• Xvid encoder has been multithreaded.
• Support for SPDIF on Windows Vista has been added ("Audio decoder configuration" -> "Output" -> "Connect to:").
• Multichannel audio processing by Winamp plugins has been added.
• In "Resize & aspect" dialog, a new check box "Process pixel aspect ratio internally" has been added.
• Resize GUI: "Specify horizontal size" instead of "Specify vertical size 0 for auto".
• Audio decoder AC3 output: the new check box "Encode only multichannel streams" allows sending multichannel audio (which otherwise cannot be digitally sent) to AV-amp in AC3-SPDIF.
