[Bug] Error saving in webp format

[Ehdil]

Hello, I'm using the program, I'm enjoying it, very good, but I have a problem that I can't save the projects in animated webp format. Whenever I try, it gives an error. What can it be?

This happens when I make a project with images and then try to record in animated webp. Thank you.

Hello, what does the error details say?

[Ehdil]

It only gives an error message. error. Here's what appears in notepad:

The last line explains the issue that you have:

Expected number for vsync but found: auto

So, for that specific selection, it's expecting a number.

Olá! :D

[Ehdil]

I'm only able to save in webp when I check the box: X Gif with repetitions. I don't know why, if it's my mistake here in the handling or if it's a bug.

If the box is checked X, even putting 1 repeat works. If I uncheck the box it gives an error message. I made a project with PNG images, with 91 frames, and saved the project, and saved from the project.

What can it be?

But the program is very good, excellent, I would like to congratulate you! And I intend to collaborate with the project in the next few days.

NickeManarin Eu gosto de informática como um todo, mas me interesso mais agora com Codecs de vídeo, codecs de áudio. Gosto do assunto. E me interessou os codecs de imagens porque estou trabalhando em um projeto e precisaria criar GIFs.

E vi esse formato Webp bem promissor, ele proporciona arquivos de tamanhos menores, que podem para algumas aplicações serem muito úteis.

Getting same problem with ScreenToGif v2.39 and the latest ffmpeg build v6.0 by gyan.
The stack trace is a bit different though.

[NickeManarin]

Which value are you using in the Loop field?

It's "-loop -1" for some reason.

[riskeez]

Which value are you using in the Loop field?

It's "-loop -1" for some reason.

When I just do File -> Save as I don't have Looped gif. flag set. And that is when it doesn't work

But if I set the flag, it works!
