v3.7.3 r4003 - TimeStretch does not have a named argument "rate"

[FlintEastwood]

The TimeStretch filter is broken. It doesnt recognize the arguments tempo, rate, pitch.
I always get the message:
TimeStretch does not have a named argument "rate"

The integer arguments like "rate_n", "rate_d" are still recognized.

Or are the arguments tempo, rate and pitch depreciated but the doku has not been changed?

TimeStretch still has two different versions. How to read: type characters 'i'=integer, 'f'-floating point, they follow [parameter_name].

c[tempo]f[rate]f[pitch]f[sequence]i[seekwindow]i[overlap]i[quickseek]b[aa]i
and
c[tempo_n]i[tempo_d]i[rate_n]i[rate_d]i[pitch_n]i[pitch_d]i[sequence]i[seekwindow]i[overlap]i[quickseek]b[aa]i

It seems to me if you'd provide floating point for rate and floating point for the preceding tempo (and not tempo_n), it would recognize?

Provide please your calling line.

I used this line:

TimeStretch(rate=100.2059891)

Is that wrong?

[pinterf]

Works fine on my system. r4003 was the 3.7.3 release, and I used the bundled TimeStretch.dll

TimeStretch(rate=100.2059891)

There must be another TimeStretch.dll on your system. Download AVSMeter64.exe (for 64 bit systems) and run it with the avsinfo option, it will list all your plugins and dates and versions.

My version:

Your version is older. It is not the version shipped with the 3.7.3 installer.

What application are you using to open the script when you see the parameter errors, and who built it?

[FlintEastwood]

I nailed down the problem a bit more.
It is NOT application dependent. It happens with VirtualDub, AVSPmod, MPC-HC, etc. .
It is a problem with the 3.7.3 TimeStretch.dll's.
I wrote a short test script, that didn't crash:

ColorBars(width=720, height=576,pixel_type="YV24")
TimeStretch(rate=100.209)

But that is not the usual way I'm writing avisynth scripts. My scripts look like this:

cv = ColorBars(width=720, height=576,pixel_type="YV24")
cv = TimeStretch(cv, rate=100.209)
return cv

And that script crashes. I tried this on a second PC with a fresh 3.7.3 install and it crashed there too.
That is the error with my video script:

But now the best:
If I'm using the TimeStretch.dll's from the 3.7.2 release (2022-03-18), then I don't get the error:
