android how to resize video width and height in surface view for media player

Question

Want to resize the video in surface view

I am Playing a video in Media Player with using a Surface view and holder for video...

// but on implementing MediaPlayerControl on some devices say Micromax, iball, Akash tablet it gives error of abstract method not available as tracked by ACRA bug tracking.

Now I want to have solution of mentioned problems:

• How to get media player controls active in all devices wihtout crashing due to abstract method as for media controller in some devices.

• How can I resize the surface view of video.

The code is working f9 on samsung galaxy gt p1000 OS 2.2 and some cheaper device WorldTeck etc.

But on Creative ziio 7 OS version is 2.2.1 (480*800) resolution density is 160 dpi video seems to be zoomed and gets cutt off from the edges.

The code is shown below:

/* Media Player Control is commented due to force close in some devices say *micromax,Creative ziio, akash etc */

    public class VideoViewerActivity extends Activity implements
            OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener,

            Log.v(TAG, "startVideoPlayback");
//also tried and used the below line but nothing good 


// holder.setFixedSize(480, 800);

holder.setFixedSize(mVideoWidth, mVideoHeight);

mMediaPlayer.start();

        }


    }

Answer 1

I used TextureView instead of surface view (it allows to rotate video) and set its setScale{X|Y}() appropriately in:

@Override
public void onVideoSizeChanged(MediaPlayer mp, int w, int h) {
    if (w > 0 && h > 0) {
        RelativeLayout.LayoutParams l;
        DisplayMetrics metrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metrics);
        l = new RelativeLayout.LayoutParams(metrics.heightPixels, metrics.widthPixels);
        l.addRule(RelativeLayout.CENTER_IN_PARENT, -1);
        float scale = (metrics.heightPixels * 1.0f) / (metrics.widthPixels * 1.0f);
        videoView.setScaleX(scale);
        videoView.setLayoutParams(l);
        Log.d(YourApp.TAG, "video size: " + mp.getVideoWidth() + "x" + mp.getVideoHeight() + " vertical scale: " + scale);
    }
}

Note that I have rotated my video, this is why I set scale for X.
