Download AviSynth 2.5.7 RC-1

The developers of AviSynth have posted on the forum of Doom9 let them know which is the first release candidate of the 2.5.7 branch downloaded can become. The update can be done via this page downloaded as an installation package and takes up approximately 3.37MB. AviSynth is – in short – a so-called frame server, a program that nestles itself “between” various programs and can therefore move video data directly from one program to another and is controlled via scripts. AviSynth is used in several video editors, including Virtual Dub, Auto Gordian Knot and DVD-Rebuilder. Such programs create scripts based on settings and options, which are then run on AviSynth, which in turn converts the video with the specified settings and options. An extensive description of AviSynth can be found in this mess post. Version 2.5.7 RC-1 has the following changes:

Notes:- I forgot to turn of the COM environment debugging option when I made this build. The final release version will not have this feature. (It can cause problems with miserable software that employs anti-debugging technology. GRR!)

additions

• Installer option for avisynth.lib, avisynth.exp and avisynth.map files.
• DirectShowSource() now sets _HIRESOUTPUT property of WMAudio Decoder DMO. Allows 24 bit samples and 6 channel decoding.
• Avisynth COM object now supports IAVIStreaming interface. Many apps blindly expect it and fail to load AVS scripts.
• Conditional Reader now also accepts T, F, Yes and No for bool data.
• DirectShowSource() log debug messages to file.
• DirectShowSource() force set framecount.
• DirectShowSource() accept audio streams or type WAVE_FORMAT_IEEE_FLOAT.
• Added KillVideo() verb.
• TimeStretch now exposes the tuning parameter of the SoundTouch library.
• Adding global OPT_AllowFloatAudio=True to your script enables WAVE_FORMAT_IEEE_FLOAT audio output.
• Explicitly request all the channels available in the audio stream [acm AC3]
• Explicitly try to request float, 32 bit then 24 bit samples from the audio codec.
• Accept raw audio streams or type WAVE_FORMAT_IEEE_FLOAT.
• Added installer option to add “Avisynth Script” item to Explorer shell for new .avs file creation.
• Added avs_delete_script_environment and avs_subframe_planar to avisynth_c interface.
• Hack to allow Fraunhoffer MP3 codec to work when wBitPerSample==16. (Squid_80)
• Added portuguese translation (by RoLon), and partly french translation (by JasonFly)
• Subtitle multi line text, set LSP arg and use \n. (foxyshadis, tateu)
• xxxFPS(“preset”) string preset FPS values. (Tritical)
• Better avisynth_c cdecl/stdcall mismatch detection and protection (Tritical).

Bug fixes

• Fixed ConvertFPS() blend mode mix_ratio was wrong.
• Fixed AviSource() handling of dud AVI files that start with drop frames, just return the first key frame.

• Fixed SubTitle() crash when resources exhausted.
• Fixed Resizer’s cropping argument validation.
• Fixed % operator bad argument text message.

• Fixed KillAudio() not resetting nchannels and sample type to 0.
• Fixed Conditional Reader sscanf buffer overrun.
• Fixed Version() and VersionString() timestamp discrepancies.
• Fixed Serious inaccuracies in TimeStretch. It is still not sample exact!
• Fixed Negative int arg handling for ApplyRange() and Animate().
• Fixed Installer handling of readonly/inuse target files.
• Fixed ConvertAudio SSE2 to Float alignment test.
• Fixed (auto)LoadPlugin altname generation. (Tritical)
• Fixed SaveString memory block overrun.
• Fixed $Plugin!Functionname!Param$ bug. (Fizick)
• Fixed registry handle leak on $PluginDir$ lookup. (Dave Brueck)
• Fixed memory leaks avisynth_c.
• Fixed returning locked/protected VBFs to LRU. (Tritical)
• Fixed runtime mixed SEH/C++ exception handling for XPsp2. (Tritical)
• Fixed CAVIStreamSynth::Read audio buffer overrun. (Avery Lee)
• Fixed DLL handle leak in LoadPlugin. (Tritical)
• Fixed Assert(“text”) no longer parses % args.
• Fixed number parser returning inaccurate float conversions.
• Fixed ConvertFPS() blend mode not processing of chroma planes.
• Fixed resizer resampling pattern attempted use after deletion.
• Fixed resizer subpixel shifting functionality being a noop.
• Fixed Info() auto font selection metric.
• Fixed Conditional error checking of float RHS.
• Corrected colors in YUV ColorBars, Now match BT.801-1.
• TCPDeliver updates: Client: Fixed crash if client gets disconnected.
• TCPDeliver updates: Server: Remember to disconnect clients when shutdown.
• Fixed Turn*() YUY2 mod 2 height test.
• Fixed AVISource() corrupted error messages.
• Fixed AVISource() direct input drop frame handling.

Optimizations

• SubTitle() releases all resources when the last frame of the clip is rendered.
• SubTitle() releases GDI resources after text map is created.
• ApplyRange() only builds 2 chains instead of 3.

changes

• Map file is now generated for release builds.
• ConvertTo*() and GreyScale() now accept “Rec601” as a valid matrix name.
• DirectShowSource.dll upx’ed.
• Upgrade internal copy of SoundTouch library to 1.3.1.
• SoundTouch now available in RelSym build.
• Animate Integer arg enumeration no longer rounds toward positive infinity. Both positive and negative enumerations are identical. ie For Animate(0, 10, “Foo”, 0, 0, 10, -10), Foo’s arg1 = -arg2 for all frames.
• Selecting associate open with Notepad with .avs files in the installer now also includes .avsi files.
• The Installer now pushes a recovery dialog box when unwritable files are encountered during an install. The user may manually correct the problem and retry installing that file.
• SetMemoryMax() minimum now 4Mb instead of 16. (Tritical)
• Remove 50 plugin auto prescan load limit. (Tritical)
• COM QueryInterface calls now return S_OK instead of NULL.
• Bracketless call of argless function now get a cache. (Tritical)
• Over-range numbers now raise a compile time exception.
• xxxFPS(float) now uses continued fraction to generate a minimal rational pair. (Raymod2)
• ChangeFPS(linear=true) now raises a compile time exception if the speed change ratio is > 10.
• ConvertFPS() blend mode works for all pixel formats. (Tritical)
• Info() retrofit or 2.60 updates.
• TCPDeliver.dll upx’ed.
• RGB ColorBars +Q and -I bars, Hue is now correct, Luma is NOT zero to achieve this.
• AVISource Audio no longer limited to 2 channels.
• SaveString memory blocks are now 32 bit aligned.
• Default planar chroma planes mod 16 aligned. See SetPlanarLegacyAlignment().
