I'm using streamlink to watch streams and lives with VLC. Recently I had my new computer and I decided to install VLC via scoop, finding that streamlink cannot work with VLC installed by scoop but work fine with manually installed VLC.
After debugging I found it might be the shim.exe issue. From what streamlink says it will pass stdin to VLC to play stream, and streamlink work fine directly with C:\Users\MyUsers\scoop\apps\vlc\current\vlc.exe, but not with C:\Users\MyUsers\scoop\shims\vlc.exe, and I didn't find any code to handle external stdin in shim.cs.
Here is how streamlink call the player:

def _open_subprocess(self, args: list[str]):
    log.debug(f"Opening subprocess: {args!r}{f', env: {self.env!r}' if self.env else ''}")

    environ = dict(os.environ)
    environ.update(self.env)

    # Force bufsize=0 on all Python versions to avoid writing the
    # unflushed buffer when closing a broken input pipe
    self.player = subprocess.Popen(
        args,
        bufsize=0,
        env=environ,
        stdin=self.stdin,
        stdout=self.stdout,
        stderr=self.stderr,
    )
    # Wait 0.5 seconds to see if program exited prematurely
    if not self.running:
        raise OSError("Process exited prematurely")

Args that should be passed to CreateProcess in shim.cs:

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
struct STARTUPINFO {
    // ...
    public IntPtr hStdInput;
    public IntPtr hStdOutput;
    public IntPtr hStdError;
}
