Question

所以我想自动播放YouTube视频。所以可用的API列表以及selenium都支持flash对象。我担心的是，如何检查视频是否正在播放？就像我可以在视频上执行运动检测一样，我可以相应地传递或失败脚本。那么我们可以用硒来实现类似吗？或硒有不同的方法来做到这一点。非常感谢

我会检查当他们点击“播放”按钮时，它会变为“暂停”图标;像这样的东西：

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Set;

import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.Select;



public class Youtube {
public WebDriver driver;
private String url = "https://www.youtube.com/watch?v=MfhjkfocRR0";

    public Youtube() {
    System.setProperty("webdriver.chrome.driver",     "C:\\SeleniumServer\\chromedriver.exe");
driver = new ChromeDriver();
//driver=new FirefoxDriver();
driver.manage().window().maximize();
driver.get(url);
}

public void waitFor(int wait){
     try {
    Thread.sleep(wait);
    } catch (InterruptedException e) {
    e.printStackTrace();
    }
}

public boolean isYoutubePlaying(){
try {
    //wait 4 secs for Youtube video to load
    waitFor(6000);
    WebElement     playPauseButton=driver.findElements(By.cssSelector("div.ytp-button")).get(0);
    //video is not playing here.
    if(playPauseButton.getAttribute("aria-label").equals("Play")){
        System.out.println("This Youtube video wasn't playing but we clicked on it to play the video.");
        //so we click on the play button to play the video then we return true;
        playPauseButton.click(); 
        return true;
    }else{
        //video should be playing but let's double-check
        if(playPauseButton.getAttribute("aria-label").equals("Pause")){
            System.out.println("Youtube video is already playing.");
            return true;
        }
    }
} catch (Exception e) {
    e.printStackTrace();
}
//only return false if either of the 2 cases above fail.
return false;
 }


}//end class

要运行此代码，只需将其实例化为：

    Youtube yt=new Youtube();
    yt.isYoutubePlaying();

如何使用selenium webdriver进行运动检测？
