[ilasdavide2011]

for some reason when i try to load a file into vhs it freezes

i'm using the powershell on windows 11
(i installed vhs with scoop)

d.tape:

# Where should we write the GIF?
Output demo.gif

# Set up a 1200x600 terminal with 46px font.
Set FontSize 46
Set Width 1200
Set Height 600

# Type a command in the terminal.
Type "echo 'Welcome to VHS!'"

# Pause for dramatic effect...
Sleep 500ms

# Run the command by pressing enter.
Enter

# Admire the output for a bit.
Sleep 5s`

and when i run vhs d.tape
it freezes with this output

I get the same -- it happens as soon as you attempt to issue any keys. I've tried with various of Type | Enter | Up | Down , the only way out is to kill the process.

> vhs --version
vhs version v0.7.1 (537d03a)

> systeminfo | findstr /B /C:"OS Name" /B /C:"OS Version"
OS Name:                   Microsoft Windows 11 Home
OS Version:                10.0.22631 N/A Build 22631

Thank you so much for the bug reports! It seems there is an issue on Windows, I will try and debug.

I have the same problem on Windows 11 in cmd.

I have the same issue. I tried to remove all the lines in the .tape file one by one until something changes. Eventually all that left was a single Output aa.gif line and it still freezes.

Windows 11, PowerShell v7.4.1

The issue seems to be that ttyd fails to start properly (crashes) on Windows 11, which results in vhs freezing before anything can be recorded.

The fix for me was to downgrade ttyd from 1.7.4 to 1.7.3 per this issue.

Thanks so much @aarol, appreciate the information!
