How to play video in VideoView?

问题:

I want to play video in VideoView. When I try to do that I got the following error:

Here is my source code:

package com.video.listitem;

import android.app.Activity;
import android.content.pm.ActivityInfo;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.widget.MediaController;
import android.widget.VideoView;

public class PlayVideo extends Activity {

     VideoView mVideoView;
     MediaController mc;
     String videourl;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.videoplay);

        try {
             mVideoView = (VideoView) findViewById(R.id.videoview);
             String videourl = "rtsp://v7.cache4.c.youtube.com/CiILENy73wIaGQl25yDUbxNXTRMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp";
             mc = new MediaController(this);
             mVideoView.setMediaController(mc);
             mVideoView.requestFocus();
             mVideoView.setVideoURI(Uri.parse(videourl));
             mc.show();
             mVideoView.start();
         } catch (Exception e) {
         //TODO: handle exception
         }  
    }
}

Here is my XML File:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scrollbars="none"
    android:gravity="center">

    <VideoView
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:id="@+id/videoview" />

</LinearLayout>

Try to run app in Device , Video may not run in Emulator...

回答2:

see my answere here in the example code provided. If video is not playing try to re-encode it with a program like Handbrake and try again. Info on supported video formats: Android Supported Media Formats

回答3:

Try to add permission to connect to internet !

uses-permission android:name="android.permission.INTERNET"

回答4:

    public void playVideo() {
            videoView = findViewById(R.id.vid);
 videoView.setVideoPath("rtsp://v7.cache4.c.youtube.com/CiILENy73wIaGQl25yDUbxNXTRMYDSANFEgGUgZ2aWRlb3MM/0/0/0/video.3gp")
            videoView.start();
        }

Just call this function in your onCreate() method

回答5:

The answer to this problem may be in this post:

Returning false or not having an OnErrorListener at all will cause the OnCompletionListener to be called.

So return true instead of false from the function and no error will be shown, i.e.

video.setOnErrorListener(new OnErrorListener() {

    @Override
    public boolean onError(MediaPlayer mp, int what, int extra) {
        Log.d("video", "setOnErrorListener ");
        return true;
    }
});

May be the url is not correct. Try to play that stream using vlc player. If it is played then we can look into other possible reason

回答7:

Ok first thing you wanna do is clean up your layout, this is your first problem:

unmesh it first and make the problem viewable:

You should have caught the error which is missing your closing cap after center", just add a ">" ... and that's it. Clean the project and you should see rtsp video. And your Internet Permission as previously stated.
