如何运行 mkv、flv、avi 格式的视频文件？

Question

我正在制作一个项目，我可以使用这个使用 videoview 的简单代码播放 3gp amd mp4 格式的视频文件

vv = (VideoView) findViewById(R.id.videoView);
vv.setVideoPath(filename);
vv.setMediaController(new MediaController(this));
vv.requestFocus();
vv.start();

我希望它也能播放 mkv、flv、avi 格式的文件。我确实搜索过这个，我得到了一个关于 votamio 的选项。我也试过了。我下载了 vitamio 的演示项目并在这个演示项目中导入了它的库，即 InitActivity，我尝试在其中播放简单的 mp4 文件，但这也没有播放。 那么谁能建议我必须做什么才能播放所有视频格式？

使用 Vitamio 更新 1：

import io.vov.vitamio.LibsChecker;
import io.vov.vitamio.MediaPlayer;
import io.vov.vitamio.widget.MediaController;
import io.vov.vitamio.widget.VideoView;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;


public class ViewVideo extends Activity {
      private String filename;
      VideoView vv;
      @Override
      public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            System.gc();
            if (!LibsChecker.checkVitamioLibs(this))
                return;
            Intent i = getIntent();
            Bundle extras = i.getExtras();
            filename = extras.getString("videofilename");
            // vv = new VideoView(getApplicationContext());
            setContentView(R.layout.activity_view);
            vv = (VideoView) findViewById(R.id.videoView);
            vv.setVideoPath(filename);
            vv.setMediaController(new MediaController(this));
            vv.requestFocus();
            vv.start();
      }
}

我用的时候

if (!LibsChecker.checkVitamioLibs(this))
                    return;

我得到的 Logcat...

Answer 1

您可以使用Vitamio 库来播放这些格式。这里是。 https://github.com/yixia/VitamioBundle

视频播放代码相同。只需导入这些并使用 Vitamio VideoView。

import io.vov.vitamio.MediaPlayer;
import io.vov.vitamio.widget.MediaController;
import io.vov.vitamio.widget.VideoView;

在 onCreateView 中检查库，如下所示。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (!io.vov.vitamio.LibsChecker.checkVitamioLibs(this))
        return;
    setContentView(R.layout.layout);

播放视频点赞

mVideoView.setVideoPath(path);
mVideoView.setVideoQuality(MediaPlayer.VIDEOQUALITY_HIGH);
mController = new MediaController(this);
mVideoView.setMediaController(mController);

以下应该是您的视频视图。

<io.vov.vitamio.widget.VideoView
 android:id="@+id/surface_view"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:layout_centerHorizontal="true"
  android:layout_centerVertical="true" />

更新：审核后在您的项目中发现以下错误。

1) 使用io.vov.vitamio.widget.VideoView 而不是我上面提到的VideoView。

<io.vov.vitamio.widget.VideoView 
        android:id="@+id/videoView"
           android:layout_width="fill_parent"
             android:layout_alignParentLeft="true"
             android:layout_alignParentTop="true"
             android:layout_alignParentBottom="true"
             android:layout_height="fill_parent"/>

2) 在您的AndroidManifest.xml 中定义InitActivity 以下是代码。

<activity
 android:name="io.vov.vitamio.activity.InitActivity"
                android:configChanges="orientation|screenSize|smallestScreenSize|keyboard|keyboardHidden|navigation"
 android:launchMode="singleTop"
 android:theme="@android:style/Theme.NoTitleBar"
 android:windowSoftInputMode="stateAlwaysHidden"/>

3) 缺少Permissions 将它们添加到您的AndroidManifest.xml 例如读/写等
