Trying to liveview on Linux an animation I made with Javis, I keep getting this error, which I couldn’t find a solution or reference to anywhere, how can I solve it?

Hey @radio :wave:

Javis developer here - could you do me a favor and answer the following:

What is your version of Julia?
What is your version of Javis?
What version of Linux are you using?
Could you please paste your code here as text?
Could you please share the full stack trace you are getting as text?

Thanks! Sorry you are running into issues with Javis. Hopefully we can get it all sorted out. :nerd_face:

Hello :), I am using Julia 1.8.1, how can I know my version of Javis?
I’m on Artix Linux with runit.
The code I’m running is:

## Background

   end
   return 1/acc
end
  
global λ  = 0.62 #gen_lambda(n)

# Display iteration points
global Q = [0,0]
global randInt = rand(1:n)
for frm in 1:totalFrames
    for _ in 1:iterPerFrame
        global randInt = sample(1:n, Weights(Ω[randInt,1:n]))
        P = [xs[randInt], ys[randInt]]
        global Q = λ * Q + (1 - λ) * P
        Object(frm:totalFrames,
               JCircle(O, pointSize, color = pointColor, action = :fill),
               Point(Q[1],Q[2]))
    end
end

render(vid; liveview=true, pathname = "Punk.gif")

And I’m not certain of what you mean by full stack trace…

I discovered my version of Javis, it’s v0.9.0

Hi,

I’m not very familiar with Javis myself. But the code you posted works if we remove the liveview = true argument to render. It successfully generates the gif too. So it seems to be a problem with just the live preview side of it.

Yes, I know. I thought I had written it somewhere, but seems I’ve forgot to mention this detail. The point is that I really want to liveview it
