I wrote a media player for playing video, but it encounter an error of
PV SW DECODER IS USED FOR MPEG4 when I try to play back a 3gp format
video, anyone knows what is it? How to solve this problem? I paste my
code below:
package com.test;
import android.app.Activity;
import android.content.Intent;
import android.content.res.AssetFileDescriptor;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.util.Log;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
public class MediaVideoTest extends Activity implements
MediaPlayer.OnPreparedListener,MediaPlayer.OnCompletionListener,SurfaceHolder.Callback
{
private static final String TAG = "MediaVideoTest";
private MediaPlayer player;
private SurfaceHolder holder;
private SurfaceView surfaceView;
private int mWidth,mHeight;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.video_view);
surfaceView = (SurfaceView) findViewById(R.id.surfaceView);
holder = surfaceView.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
private void playVideo() {
try {
AssetFileDescriptor asd =
getResources().openRawResourceFd
(R.raw.chainsaw);
//create media player
player = new MediaPlayer();
player.setDataSource(asd.getFileDescriptor(),asd.getStartOffset
(),asd.getLength());
player.setDisplay(holder);
player.prepare();
player.setOnPreparedListener(this);
player.setOnCompletionListener(this);
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (Exception e) {
Log.e(TAG, "error: " + e.getMessage(), e);
}
}
@Override
public void onPrepared(MediaPlayer mp) {
Log.d(TAG, "onPrepared called");
mWidth = player.getVideoWidth();
mHeight = player.getVideoHeight();
Log.d(TAG, "width : " + mWidth + " height : " + mHeight);
if(mWidth != 0 && mHeight != 0){
holder.setFixedSize(mWidth, mHeight);
player.start();
}
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int
width,int height) {
Log.d(TAG, "surfaceChanged width : " + width + " height : " +
height);
}
@Override
public void surfaceCreated(SurfaceHolder holder) {
Log.d(TAG, "surfaceCreated() is called");
playVideo();
}
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
Log.d(TAG, "surfaceDestroy() is called");
}
@Override
protected void onDestroy() {
super.onDestroy();
if(player != null){
player.release();
player = null;
}
}
@Override
public void onCompletion(MediaPlayer mp) {
if(player != null){
player.release();
player = null;
}
//close this activity;
finish();
//go back to the main menu
Intent intent = new Intent(this,MediaTest.class);
startActivity(intent);
}
}
