使用 Ruby 处理导出 QuickTime 影片

Question

我正在使用 Ruby-Processing 来制作一个处理应用程序。如何导出应用程序的 QuickTime 影片？

我已尝试以下操作：

load_library 'video'
import 'processing.video.MovieMaker'

def setup
  # stuff...
  @mm = MovieMaker.new(WIDTH, HEIGHT, "drawing.mov", 30, MovieMaker.H263, MovieMaker.HIGH)
end

def draw
  # stuff...
  @mm.add_frame
end

def mouse_pressed
  @mm.finish_movie
end

但这似乎不起作用，并且出现此错误：

知道出了什么问题吗？

Answer 1

我猜您正在运行 Mac OS。
在这种情况下，您必须强制 JVM 处于 32 位模式。 2 种可能性：

• 进入 Utilities > Java Preferences 并将 32 位线拖到列表顶部。这应该可以解决问题。
• 或者获取最新的 ruby-processing (gem install ruby​​-processing)，并将以下行放入 YAML 配置文件 $HOME/.rp5rc

java_args：-d32

这将强制 JVM 处于 32 位模式。

希望这有帮助。
