Does anyone know avss.dll (ala DSS) from Haali?

[Wilbert]

According to http://forums.animesuki.com/showthread.php?t=48608, there is an AviSynth plugin called avss.dll created by Haali (which can be obtained from the Haali Media Splitter).

DSS2 is Haali's implementation of Directshowsource. It has the advantage of being frame-accurate, but only supports VFR by converting it to CFR; at least that was the case when I tried it last time, it might have changed.

The point being is whether it is based on DSS, since DSS2 is closed source. I will ask him about it.

[Myrsloik]

As someone who happens to be in possession of the full source for dss2 I can tell you that it uses directshow and that's where the similarities end. There are no violations and in my opinion the only thing you'll develop with this line of questioning is a bad reputation...

[TheFluff]

You didn't notice this plugin until now? It's been around for years.

Also I wonder how your logic behind posting this thread went, was it something like "hey it has 'directshow' in the name so it must be a derivative, I better post a thread on doom9 about it to stir up some drama while I wait for Haali to answer" or what?

[Wilbert]

Oh c'mon, that was never my intension. I was just curious about the plugin since i hadn't seen it before. My apologies if anyone is offended and sorry that i took your words too literally.

[TheFluff]

Well if this is going to be turned into a general DSS2 thread... the syntax is:
dss2(string infile, float fps)
i.e.
loadplugin("avss.dll")
dss2("X:/test.mkv",fps=23.976)

Unlike the original DSS, it does not support loading audio. It also always converts VFR to CFR; i.e. it acts like the original DSS with convertfps=true does.

[cooolway]

how do I load audio from my video as it doesn't with DSS2?

[Myrsloik]

You don't, it's not supported in DSS2. Use another method and audiodub.

For posterity and completeness of this thread, there were some reported "challenges" with it. See near the end of this post http://forum.doom9.org/showthread.php?p=1285639#post1285639

Do I need to have Haali installed/registered in order to use dss2? because I just took avss.dll and uninstalled haali and now it doesn't work. I'd like to use it while keeping the system as clean of Haali as possible.

Well, DSS2 uses DirectShow, obviously. So you will need the suitable DirectShow filters (splitters and decoders) installed/registered on your system. Consequently for MKV or MP4 or TS files you'll need the Haali Media Splitter or something that can do the same job.

[IanB]

Dss2 uses the frame grab feature of Haali's directshow renderer.

So you need that as a minimum.

It is does not normally include itself in default graphs.

[Dogway]

It's for a wmv source.
I use lavfilters+ffdshow(wmv9)+madvr.

Can I then take the Haali's renderer files and copy them somewhere where it is requested?

You will have to register the COM interface, I think.

C:\Program Files (x86)\Haali\MatroskaSplitter>regsvr32 splitter.ax

Looks like it turns practically into a manual install, I will check. Is ffms2 a worse option than dss2 for VC-1 sources?

What container? TS will probably work very badly, other containers I don't know since I haven't tried it.

[Dogway]

wmv, I get eventual artifacts when frameskipping with ffms2. Not sure if its so at encoding...

Does anyone know how to contact the author of this plugin? Of course, assuming that he willing to fix (or at least take a look at) some bugs..

Report your bug, others may know the answer ....

[forclip]

Thanks.

The bugs:
1. This plugin can't handle a files that contains a symbols from my local CodePage. So it can't be used with (for example) C:\файл.mkv.

2. It may hangs when processing the last frames. Sure, this behavior may be related to splitters\decoders that's being used, but the same files works fine with DirectShowSource.

P.S. I don't looking for a workarounds, no need to point me to FFMS2, DGDecNV and so on.

[IanB]

1. Avss.cppHRESULT hr = dss2->OpenFile(CA2WEX<128>(filename, CP_OEMCP), avgframe);
DirectShowSource.cppMultiByteToWideChar(CP_ACP, 0, filename, -1, filenameW, MAX_PATH);
There is a whole thread dedicated to non-ascii characters in scripts.

2. The avss code seems predictable, I suspect the frame grab code in the renderer is getting caught. (I don't have the renderer code :( ) Sorry I can't help.

[forclip]

1. Avss.cpp
So you have the sources for this plugin? :)

Sorry for being paranoid, but I have to ask, since Haali's renderer only supports yuy2 and rgb32 input.

Does dss2 keep the decoded video data in yv12 colorspace, or does it in fact force a colorspace conversion? I don't think the latter is likely to be the case, but I'd like to get a confirmation, if someone can give one!

[IanB]

So you have the sources for this plugin? :)No, I only have some of the source.

[TheRyuu]

It seems the avss source package that I have contains the fix mentioned by IanB so perhaps it was updated at somepoint.

Thanks! Unfortunately, I still can`t open my "C:\файл.mkv", so I think that avss.dll that I had before was already "fixed". May be this issue is similar to this one (http://doom10.org/index.php?topic=25.msg4659#msg4659):

DirectShow probably expects Unicode strings only and FFMS2 isn't converting them before passing them to the splitter or something.

Huh! :confused: This source still uses CP_OEMCP (Dosbox code page) instead of CP_ACP (Windows code page).

To test this theory, create the .AVS in something using the OEM code page like Edit under Cmd.exe.



Also thanks TheRyuu for the full source code :D

Replaced, and it did the trick! :)

For some reason I thought you hilighted it because it was what changed in your original post. I didn't see the correlation between 1 and 2, brainfart.
