Android：如何播放资产中的视频？

Question

I am making an application in which I have to show video from assets folder in a Fragment . Can anyone help me do this? Do I need to use VideoView in XML?

Answer 1

Instead of accessing from assests,You must copy the video into your project's res/raw folder. Create raw folder under res folder. It must be in a supported format (3gp, wmv, mp4 ) and named with lower case, numerics, underscores and dots in its filename likewise:video_file.mp4.

VideoView view = (VideoView)findViewById(R.id.videoView);
String path = "android.resource://" + getPackageName() + "/" + R.raw.video_file;
view.setVideoURI(Uri.parse(path));
view.start();

Answer 2

VideoView view = (VideoView)findViewById(R.id.videoView);
String path = "android.resource://" + getPackageName() + "/" + R.raw.video_file;
view.setVideoURI(Uri.parse(path));
view.start();

It's AkashG's code, but I remember that R here is not from the Android class. It's from your own project.

You first need to convert your video into the InputStream and then save it to the user's internal storage, then display it and delete that file when the video is finished.

try{
     String path = Environment.getExternalStorageDirectory()+"/"+APP_NAME()+"/videos/"+ls+"/" ;
     InputStream input = getAssets().open("vid/dal.mp4");
     String name = System.currentTimeMillis() +".mp4";
     File f = new File(path);
     f.mkdirs();
     int size = input.available();

     FileOutputStream output = new FileOutputStream(new File(path+name));
     byte data[] = new byte[4096];
     long total = 0;
     int count;
     while ((count = input.read(data)) != -1) {
          output.write(data, 0, count);
          total += count;
          if (size <= total) {
              break;
          }
     }
     output.flush();
     output.close();
     input.close();

     //Toast.makeText(VideoPlayer.this , "file created !" , Toast.LENGTH_LONG).show();

     Uri uri = Uri.parse(path+name) ;

     videoView.setVideoURI(uri);

     videoview.start();

}cath(Exception e){
}

I have already suffered from same problem, u should prefer project's res/raw folder instead of assets. Create raw folder under res folder. Save video file in a supported format (3gp, wmv, mp4 ) and named with lowercase, numerics, underscores and dots in its filename likewise:filename.3gp into the raw folder.

VideoView videoview = (VideoView) findViewById(R.id.VideoView);

String uriPath = "android.resource://your application package name/raw/your 
wmv/mp4/3gp file in res/raw path without extension";

videoview.setVideoURI(Uri.parse(uriPath));

videoview.start();

Answer 5

you can use the MediaItem to play a video from assets

    val playerView = view.findViewById<StyledPlayerView>(R.id.player)

    val player = ExoPlayer.Builder(context!!).build()
    
    val videoUri = Uri.parse("asset:///test.mp4")
    val item = MediaItem.fromUri(videoUri)

    player.addMediaItem(item)
    playerView.player = player

    player.prepare()

Answer 6

Playing Video(sample.mp4) present in res/ raw folder, along with the Media Controller

// Import Statements

import android.widget.VideoView;
import android.widget.MediaController;

public class youractiviy extends Activity {

private VideoView videoView;
private MediaController mediaController;

protected void onCreate(Bundle savedInstanceState) {
 // Your Startup code
 videoView = (VideoView) findViewById(R.id.video_view);
 videoView.setVideoPath("android.resource://" + getPackageName() + "/" + R.raw.sample); 
 mediaController = new MediaController(TestActivity.this);
 mediaController.setAnchorView(videoView);
 videoView.setMediaController(mediaController);
 videoView.start();

}
}

// XML Code

<VideoView
        android:id="@+id/video_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
