Exactly! You want to measure the pipe speed before an actual encoding application . Because that is how it would be used in real usage scenario. IMO , that is more useful information

Code:
vspipe --y4m script.vpy - | ffmpeg -f yuv4mpegpipe -i - -an -f null NUL
Code:
ffmpeg -i script.avs -an -f null NUL

Thank you. nfMakeLinear is undefined. Do I need more recent headers?

Yes, I will export frame info.

Do I still need to do this:

muldivRational(&VI[0].fpsDen, &VI[0].fpsNum, 1, 1);

You need newer headers and you still need to do that

What is the Vapoursynth equivalent of:

env->SetVar(env->Sprintf("%s", "FFPICT_TYPE"), static_cast<int>(ctype));

If the picture type is a single char you'd do something like this:
Code:
VSMap *Props = vsapi->getFramePropsRW(Dst);
vsapi->propSetData(Props, "_PictType", &Frame->PictType, 1, paReplace);

Note that many properties have standard names and types. See this part of ffms2 for hints.

No properties are required but a list of what you should call some things if you do attach them is here. For example all the colorpsace stuff gets used by format conversions automatically then.

You're free to make up your own properties too as long as they don't start with _.

I don't know if pipe does cause that large overhead or it's the limitation of ffmpeg itself.

It is what we currently use. If there is overhead, than means if you use ffmpeg to encode, that overhead is currently incurred in real practice too - i.e it reflects reality. If you were to encode, say using libx264, it would be marginally slower because of that penalty

But I would like to compare "apples to apples" someday. It is a dream. Maybe with this

maybe quote it before it might disappear

Thanks for the testing!

It's just 1 test so far, but 4.5% faster is still significant. But when coupled with actual encoding (-c:v something), you'd expect that difference to drop more

Doesn't work for me. Constantly still says no such function z_ConvertFormat. I put it under plugins+ in AviSynth+ Prog Files x86 :/

Using FFMS2 for a 4K mkv...what am I doing wrong?

Run "AVSMeter avsinfo" (or "AVSMeter64 avsinfo") and let us know if that produces any errors.
It's quite possible that you don't have the required runtimes installed.

AVSMeter just crashes, assuming its flipping out because that function doesn't exist apparently.

AviSynth+ 0.1 (r1576, x86) (2.6.0.5)

Script error: There is no function named 'z_ConvertFormat'.
(C:\Users\Desktop\AVSMeter281\New File (1).avs, line 2)

1. Update AVS+ to the most recent version
2. Read my last post again - The command line should be "AVSMeter avsinfo"

Updating worked. Thank you kindly!

I love avsmeter. It's amazing for diagnosis. I'm surprised I'm JUST now finding out about your tool!
