How to play videos in android from assets folder or raw folder?

I am trying to play a video in android emulator I have the video in my assets folder as well as the raw folder But after doing some research still i cant play video in my emulator i am working on android 2.1 My video format is mp4 so i don't think that should be a problem Could anyone just give me an example code so that i can understand a bit more?

The problem is that the VideoView that I need to display the Video will take only a URI or a File path to point to the Video.

If I save the video in the raw or assets folder I can only get an input stream or a file descriptor and it seems nothing of that can be used to initialize the VideoView.

Update

I took a closer look at the MediaPlayer example and tried to start a MediaPlayer with a FileDescriptor to the assets files as in the code below:

SurfaceView videoView = (SurfaceView) findViewById(gettingStarted)
SurfaceHolder holder = videoView.getHolder();
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
final MediaPlayer player = new MediaPlayer();
player.setDisplay(holder);

player.setDataSource(getAssets().openFd(fileName).getFileDescriptor());
player.prepareAsync();
player.setOnPreparedListener(new OnPreparedListener() {

   @Override
   public void onPrepared(MediaPlayer mp) {
      mp.start();
   }
});

Now I get a the following exception:

java.io.FileNotFoundException: This file can not be opened as a file descriptor; it is probably compressed

It seems there is no other way then copying the file to the sdcard on startup and that seems like a waste of time and memory.

Solution 1:

## Perfectly Working since Android 1.6 ##

getWindow().setFormat(PixelFormat.TRANSLUCENT);
VideoView videoHolder = new VideoView(this);
//if you want the controls to appear
videoHolder.setMediaController(new MediaController(this));
Uri video = getUriFromRawFile(context, R.raw.your_raw_file);
//if your file is named sherif.mp4 and placed in /raw
//use R.raw.sherif
videoHolder.setVideoURI(video);
setContentView(videoHolder);
videoHolder.start();

And then

public static Uri getUriFromRawFile(Context context, @ResRaw int rawResourceId) {
    return Uri.Builder()
        .scheme(ContentResolver.SCHEME_ANDROID_RESOURCE)
        .authority(context.getPackageName())
        .path(String.valueOf(rawResourceId))
        .build();
}

Solution 2:

String UrlPath="android.resource://"+getPackageName()+"/"+R.raw.ur file name;
videocontainer.setVideoURI(Uri.parse(UrlPath));
videocontainer.start();

where videocontainer of type videoview.

Solution 3:

Try:

AssetFileDescriptor afd = getAssets().openFd(fileName);
player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(), afd.getLength());
