Question

我已将Red5-Screenshare应用程序（在下面的链接中找到）转换为JApplet;

https://code.google.com/p/red5-screenshare/

我刚刚从JApplet扩展了ScreenShare.java类。然后我删除了main（）方法并在ScreenShare.java类中放置了以下applet init（）方法。

public  void init()
{
    instance = new ScreenShare();


    instance.host = getParameter("host");
    instance.app = getParameter("app");
    instance.port =  Integer.parseInt(getParameter("port"));
    instance.publishName = getParameter("stream");
    instance.codec = getParameter("codec");

    try {
        instance.frameRate = Integer.parseInt(getParameter("framerate"));
        instance.maxWidth = Integer.parseInt(getParameter("width"));
        instance.maxHeight = Integer.parseInt(getParameter("height"));
        logger.debug(instance.maxWidth +","+instance.maxHeight);

    } catch (Exception e) {logger.debug(e.getMessage());}

    System.out.println("User home " + System.getProperty("user.home"));
    System.out.println("User Dir " + System.getProperty("user.dir"));


    logger.debug("host: " + instance.host + ", app: " + instance.app + ", port: " + instance.port + ", publish: " + instance.publishName);

    instance.createWindow();
}

这就是这个applet的JNLP文件的样子

注意：我正在按照此链接上的建议在页面上嵌入JNLP https://docs.oracle.com/javase/tutorial/deployment/deploymentInDepth/embeddingJNLPFileInWebPage.html

当我在浏览器中运行JApplet时，屏幕共享流看起来很模糊，如下图所示。但是，当我从eclipse运行相同的JApplet时，流根本不会模糊！

blurred screenstream

知道我做错了吗？

Answer 1

现在在scala中提供了BBB中的SessionManager，因此您可以看到方法here的签名并创建一个实现它们的java类。然后将导入更改为您的类，它将构建。

Answer 2

在将屏幕宽度和高度参数更改为sWidth和sHeight后，我修复了red5-screenhare applet。因为applet将其画布宽度和高度视为屏幕尺寸，导致屏幕捕获模糊。
