Hi, thanks for the issue report!

Can you confirm for us whether this is reproducible using mainline SVT-AV1? Thanks so much.

@gianni-rosato

Right now, I am unable to check with standalone mainline SVT-AV1. But I can encode with ffmpeg that enable SVT-AV1 (not sure it because ffmpeg handle the pipe from vapoursynth to avoid this issue).

I use the release bin in your release repo and the issue still exists.

Also I try to use the community build from here and it works.

[gianni-rosato]

So you're saying the community build works but the official build doesn't?

@gianni-rosato

Yes, I can confirm the community build works but the official build doesn't

[gianni-rosato]

Gotcha, thanks for the additional information. We're going to be taking the official build down shortly, and in the future, official Windows builds will not be provided.

@gianni-rosato

Sad, I hope you guys still support official build for windows.
