使用Ruby-Processing导出QuickTime影片

我正在使用Ruby-Processing制作处理应用。如何导出我的应用程序的QuickTime影片？

我尝试了以下内容：

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，我得到了这个错误：

知道什么是错的吗？

1 个答案:

答案 0 :(得分：1)

我猜你正在运行Mac OS。
在这种情况下，您必须以32位模式强制JVM。 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。
  • 或者抓取最新的ruby-processing (gem install ruby-processing)，并将以下行放在YAML配置文件中$HOME/.rp5rc
  

java_args：-d32

这会强制JVM采用32位模式。

希望这有帮助。
