AviSynth 2.6.0 RC1 [Jan 14th, 2015]

Here is the 6th official release of Avisynth 2.6!!!

Get AviSynth_150114.exe (6.21MB) from SourceForge.

I hope you will all help in testing the new features. The documentation is updated, so please check out. For the plugin writers, the FilterSDK and the c-api got a big update. I'm sure you will enjoy it. If no bugs will be found we will make it final.

Perhaps you have noted, although Ian submits stuff now and then to sourceforge, I'm not sure he will return to this forum. I'm sure you will notice if he does I marked the differences with respect to alpha5 in bold.

========================
Changelist

Additions
========
* AviSource: added multiple video and audio track support.
* Add IScriptEnvironment::GetVarDef() nothrow version of GetVar().

The out of memory message looks like this now:



For better readability, I would suggest to format the values to MB.

Does this means AVI with 2 audio streams can be worked with without having to extract the second stream?

No, that's not possible. I have no idea how to make that possible, or if it is possible at all without breaking everything.
The functionallity is the same as ffmpegsource. So you can open them one by one (with two avisource calls) if you want to process them both and export them one by one.

Wait, you mean i can open 2 Avisource from one file.
And tell:

A = Stream 1
B = Stream 2

If so i don't need to export anything for what i am doing.

It will remain v2.5 folder till v2.6 full version released.

EDIT: Based on reply to similar question answered by IanB (IIRC).

I don't know if the name of the folder will be changed, since the current one seems more convenient to me. When installing a new 2.6 you don't need to look in two folders for deinstalling older versions. Will ask Ianb about it.

It may be a good time to change the folder name to "AviSynth" only. Logically change may involve some small complication but only would this time.

Can confirm the Audiotrack thing i asked about.

You can do stuff like:

A = Avisource("myvideo",atrack=0)
B = Avisource("myvideo",atrack=1)
A.Mixaudio(B)

(Hope i did that correct now).

Such a feature i have been waiting a long time for, and i thought it wasn't possible as i asked about it.
Very thankful for it to have been implemented

After months of AviSynth abstinence, I just started a V2.6 plugin to substitute AudioGraph. Now I'm struggling with the C++ API, especially the
Code:
PClip ok_clip = ConvertAudio::Create(_clip, SAMPLE_INT16|SAMPLE_FLOAT, SAMPLE_FLOAT);
part in the 'AviSynthTwoFiveAudio' doc, encountering a linkage error
Code:
Error	1	error LNK2001: Unresolved external symbol ""public: static class PClip __cdecl ConvertAudio::Create(class PClip,int,int)" (?Create@ConvertAudio@@SA?AVPClip@@V2@HH@Z)".
and wondering by what the shortly removed ConvertAudio reference in the AviSynth.h header might have been replaced, as I find no documentation in the AviSynth26RC1 package, and also forum search with keyword 'ConvertAudio' gives no clue.

EDIT: though I also wonder how this worked before, as the lines were inside a #if 0 ... clause. Did anyone write a plugin on this platform yet, or can give a really working examplee?
