How to play Youtube videos in Android Video View?

问题:

I am developing an android application which requires a youtube video player embedded within it. I successfully got the RTSP video URL from the API, but while trying to load this rtsp url in my android video view, it says "Can't play this video.". Previously I developed a similar application in this method, and it worked fine at that time, but it also failing to load now.

I'm sure about that, I'm getting the correct RTSP url from the API. rtsp://v6.cache6.c.youtube.com/CiULENy73wIaHAlV9VII3c64lRMYESARFEgGUglwbGF5bGlzdHMM/0/0/0/video.3gp

Here is my activity code:

    mVideoURL = getIntent().getStringExtra("EXT_URL");
    Log.i("VIDEO URL", " " + mVideoURL);

    MediaController mc = new MediaController(this);
    mVideoStreamView = (VideoView) findViewById(R.id.vidPlayer);

    mVideoStreamView.setVideoURI(Uri.parse(mVideoURL));
    mVideoStreamView.setMediaController(mc);
    mVideoStreamView.requestFocus();
    mVideoStreamView.start();

EDIT Found some additional information from the logcat:

Please suggest me a way to load youtube videos in android video view.

Thanks in Advance...

EDIT Just checked in another device, HTC Desire (2.2). The code worked fine. I'm wondering about thinking, What will be the problem with Nexus (4.1)??

回答1:

As I can't find any way to load the rtsp URL in video view (for all devices & android versions), I solved my problem with another work around. I used a webview to embed the youtube player within it, and this method working nicely in all tested devices.

Here is my code:

mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginState(PluginState.ON);
mWebView.loadUrl("http://www.youtube.com/embed/" + videoID + "?autoplay=1&vq=small");
mWebView.setWebChromeClient(new WebChromeClient());

Thank you very much for all your help guys.

Due to current version of YouTube you are likely to get a “Can’t play this video” error if you will use VideoView to show your video.

Take a look at this approcach with YouTubePlayerView: http://xinyustudio.wordpress.com/2014/03/17/android-development-play-youtube-video-in-your-app-cant-play-this-video-and-troubleshooting/

回答4:

Use YouTube Android Player API. It works perfectly. Check my example from here:

activity_main.xml:

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"

tools:context="com.example.andreaskonstantakos.vfy.MainActivity">

<com.google.android.youtube.player.YouTubePlayerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="visible"
android:layout_centerHorizontal="true"
android:id="@+id/youtube_player"
android:layout_alignParentTop="true" />

<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="195dp"
android:visibility="visible"
android:id="@+id/button" />


</RelativeLayout>

MainActivity.java:

package com.example.andreaskonstantakos.vfy;


import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayerView;



public class MainActivity extends YouTubeBaseActivity {

YouTubePlayerView youTubePlayerView;
Button button;
YouTubePlayer.OnInitializedListener onInitializedListener;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

     youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player);
     button = (Button) findViewById(R.id.button);


     onInitializedListener = new YouTubePlayer.OnInitializedListener(){

         @Override
         public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {

            youTubePlayer.loadVideo("Hce74cEAAaE");

             youTubePlayer.play();
     }

         @Override
         public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

         }
     };

    button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

youTubePlayerView.initialize(PlayerConfig.API_KEY,onInitializedListener);
        }
    });
}
}

and the PlayerConfig.java class:

  package com.example.andreaskonstantakos.vfy;

/**
 * Created by Andreas Konstantakos on 13/4/2017.
 */

public class PlayerConfig {

PlayerConfig(){}

public static final String API_KEY = 
"xxxxx";
}

Replace the "Hce74cEAAaE" with your video ID from https://www.youtube.com/watch?v=Hce74cEAAaE. Get your API_KEY from Console.developers.google.com and also replace it on the PlayerConfig.API_KEY. For any further information you can follow the following tutorial step by step: https://www.youtube.com/watch?v=3LiubyYpEUk

Checkout this link . It explains how to implement youtube video in VideoView.

回答6:

Using Video View:

1.Code in the layout xml:

<VideoView

       android:layout_width=”wrap_content”

       android:layout_height=”wrap_content”

       android:id=”@+id/YoutubeVideoView” />

2.Code in java class:

VideoView v = (VideoView) findViewById(R.id.YoutubeVideoView);

v.setVideoURI(Uri.parse(“rtsp://v4.cache3.c.youtube.com/CjYLENy73wIaLQlW_ji2apr6AxMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoYOr_86Xm06e5UAw=/0/0/0/video.3gp”));

v.setMediaController(new MediaController(this)); //sets MediaController in the video view

// MediaController containing controls for a MediaPlayer                            

v.requestFocus();//give focus to a specific view

v.start();//starts the video

We set the VideoUri by specifying the 3gp link of Youtube video for mobile platforms. To add media controls such as Play, Pause, Rewind, Fast Forward and a progress slider ,we add MediaController to the VideoView.

uri.parse( 3gp link of the video )...you can get this from youtube

回答7:

It depends on which Video codec format you are recieving your rtsp. There are certain devices which do not support running .mp4 file. Go through Android Media support for more information. Check if you can play any other .3gp files or not.

回答8:

After a long search, I found this way of implementation.

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.about_fragment, container, false);

    String frameVideo = "<html><body><br><iframe width=\"320\" height=\"200\" src=\"https://www.youtube.com/embed/XDYbEuY8nIc\" frameborder=\"0\" allowfullscreen></iframe></body></html>";

    WebView displayYoutubeVideo = (WebView) rootView.findViewById(R.id.videoView);
    displayYoutubeVideo.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return false;
        }
    });
    WebSettings webSettings = displayYoutubeVideo.getSettings();
    webSettings.setJavaScriptEnabled(true);
    displayYoutubeVideo.loadData(frameVideo, "text/html", "utf-8");
  return rootView;
    }

inside the layout.xml:

 <WebView android:id="@+id/videoView"
            android:layout_height="wrap_content"
            android:layout_width="match_parent"
            android:layout_marginTop="-45dp"
            android:layout_marginLeft="-5dp"/>

This will work well.
