I have been working on video playback of progressive videos from my android application. I am able to stream videos from internet.
But the video starts after buffering the whole data.
Here is the code I am using-
private static final String MOVIEURL = "movieUrl";
private static final String TAG = "VideoPlayerActivity";
private int mVideoWidth;
private int mVideoHeight;
private MediaPlayer mMediaPlayer;
private SurfaceView mPreview;
private SurfaceHolder holder;
private String path;
private Bundle extras;
private boolean mIsVideoSizeKnown = false;
private boolean mIsVideoReadyToBePlayed = false;
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.mediaplayer_2);
mPreview = (SurfaceView) findViewById(R.id.surface);
holder = mPreview.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
extras = getIntent().getExtras();
}
private void playVideo(String movieUrl) {
doCleanUp();
try {
path=movieUrl;
// Create a new media player and set the listeners
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(path);
mMediaPlayer.setDisplay(holder);
mMediaPlayer.prepare();
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setOnVideoSizeChangedListener(this);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (Exception e) {
Log.e(TAG, "error: " + e.getMessage(), e);
return false;
}
}
public void onBufferingUpdate(MediaPlayer arg0, int percent) {
Log.d(TAG, "onBufferingUpdate percent:" + percent);
}
public void onCompletion(MediaPlayer arg0) {
Log.d(TAG, "onCompletion called");
}
private void doCleanUp() {
mVideoWidth = 0;
mVideoHeight = 0;
mIsVideoReadyToBePlayed = false;
mIsVideoSizeKnown = false;
}
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
Log.v(TAG, "onVideoSizeChanged called");
if (width == 0 || height == 0) {
Log.e(TAG, "invalid video width(" + width + ") or height(" + height + ")");
return;
}
mIsVideoSizeKnown = true;
mVideoWidth = width;
mVideoHeight = height;
if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) {
startVideoPlayback();
}
}
public void onPrepared(MediaPlayer mediaplayer) {
Log.d(TAG, "onPrepared called");
mIsVideoReadyToBePlayed = true;
if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) {
startVideoPlayback();
}
}
public void surfaceChanged(SurfaceHolder surfaceholder, int i, int j, int k) {
Log.d(TAG, "surfaceChanged called");
}
public void surfaceDestroyed(SurfaceHolder surfaceholder) {
Log.d(TAG, "surfaceDestroyed called");
}
public void surfaceCreated(SurfaceHolder holder) {
Log.d(TAG, "surfaceCreated called");
playVideo(extras.getString(MOVIEURL));
}
#Override
protected void onPause() {
super.onPause();
releaseMediaPlayer();
doCleanUp();
}
#Override
protected void onDestroy() {
super.onDestroy();
releaseMediaPlayer();
doCleanUp();
}
private void releaseMediaPlayer() {
if (mMediaPlayer != null) {
mMediaPlayer.release();
mMediaPlayer = null;
}
}
private void startVideoPlayback() {
Log.v(TAG, "startVideoPlayback");
holder.setFixedSize(mVideoWidth, mVideoHeight);
mMediaPlayer.start();
}
This code is working fine, but not playing before the whole video gets buffered.
Is there anyway we can stream the video while buffering it in the background.
Thanks.
Instead of
mMediaPlayer.prepare();
Use :
mMediaPlayer.prepareAsync();

I want to play a live HTTP stream in my Android app, so I installed the Windows Media Encoder 9 on another PC on the same LAN, and used it to create a live HTTP audio stream.
The live HTTP stream is okay: I tested it, and it can be played by Windows Media Player or VLC on a PC, and can be played by VLC for Android on my mobile.
So, in my Android app, I wrote this code:
private MediaPlayer player = null;
#Override
public void onCreate(Bundle savedInstanceState) {
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork() // or .detectAll() for all detectable problems
.penaltyLog()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
//.detectLeakedClosableObjects()
.penaltyLog()
.penaltyDeath()
.build());
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnPlay = (Button)findViewById(R.id.play);
address = (TextView)findViewById(R.id.address);
btnPlay.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
play();
}
});
}
private void play()
{
String serverIp;
serverIp = address.getText().toString(); // get the uri address, for example http://xxx.xxx.xxx.xxx:2340
if (player == null)
{
player = new MediaPlayer();
}
else
{
player.stop();
player.reset();
}
try {
Log.v("", "Init a new MediaPlayer");
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
Log.v("", "Set the stream type to STREAM_MUSIC");
player.setDataSource(this, Uri.parse(serverIp));
Log.v("", "Set the source is " + serverIp);
player.setOnBufferingUpdateListener(this);
player.setOnPreparedListener(this);
player.setOnErrorListener(this);
player.prepareAsync();
Log.v("", "After prepareAsync");
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
Log.v("IllegalArgumentException", e.toString());
} catch (SecurityException e) {

Log.v("SecurityException", e.toString());

}

return true;
}

return true;
}
But it didn’t work. When I click the play button, nothing happens. But if I input some other URL I found on the internet (for example, http://www.example.com/song.mp3), it works.
So can anyone help me? The Log info is below. My mobile is HTC s710e, and my Android version is 4.0.4.

you can play HLS on android 3.0and 3.0 + version, older versions doesnt support HLS. This code below, can work on 3.0 + version. To play video all android version you have to use rtsp streaming or http prograssive download.

So I have been interested in programming for the Google TV for a while now, and have just started to get into it.
My first personal project is to create a simple media player and file browser, since the default media player is so awful. It works perfectly on the Android emulator (version 12), but when I install it into my Google Revue I find myself facing two major problems.
1) The player will always play the first movie alphabetically, no matter which movie file is chosen (all of the formats and paths are correct. URI loaded into setDataSource/setVideoPath)
2) Whenever I try to fast forward through a movie, it skips to the next movie alphabetically instead
I have used the mediaplayer and videoview examples from the android development website here: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/media/index.html
as well as the default action_view intent, but have the exact same problem with every single one. The movie will play 100% fine on the emulator, but have completely different defaults on the Google Revue.
Has anybody encountered this problem before or have any idea what I can do/where I can go to fix it?
EDIT
Here is my code to call the activity:
Intent intent = new Intent(getBaseContext(), myMediaPlayer.class);
intent.putExtra("PATH_ID", path);
startActivity(intent);
Here is my code to run the mediaPlayer. (pretty much an exact copy of the website's code)
public class myMediaPlayer extends Activity implements
OnBufferingUpdateListener, OnCompletionListener,
OnPreparedListener, OnVideoSizeChangedListener, SurfaceHolder.Callback {
private static final String TAG = "MediaPlayerDemo";
private int mVideoWidth;
private int mVideoHeight;
private MediaPlayer mMediaPlayer;
private SurfaceView mPreview;
private SurfaceHolder holder;
private String path;
private String extras;
private boolean mIsVideoSizeKnown = false;
private boolean mIsVideoReadyToBePlayed = false;
/**
*
* Called when the activity is first created.
*/
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.mediaplayer);
mPreview = (SurfaceView) findViewById(R.id.surface);
holder = mPreview.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
extras = getIntent().getExtras().getString("PATH_ID");;
}
private void playVideo(String filePath) {
doCleanUp();
try {
path = filePath;
// Create a new media player and set the listeners
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(path);
mMediaPlayer.setDisplay(holder);
mMediaPlayer.prepare();
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setOnVideoSizeChangedListener(this);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (Exception e) {
Log.e(TAG, "error: " + e.getMessage(), e);
}
}
public void onBufferingUpdate(MediaPlayer arg0, int percent) {
Log.d(TAG, "onBufferingUpdate percent:" + percent);
}
public void onCompletion(MediaPlayer arg0) {
Log.d(TAG, "onCompletion called");
}
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
Log.v(TAG, "onVideoSizeChanged called");
if (width == 0 || height == 0) {
Log.e(TAG, "invalid video width(" + width + ") or height(" + height + ")");
return;
}
mIsVideoSizeKnown = true;
mVideoWidth = width;
mVideoHeight = height;
if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) {
startVideoPlayback();
}
}
public void onPrepared(MediaPlayer mediaplayer) {
Log.d(TAG, "onPrepared called");
mIsVideoReadyToBePlayed = true;
if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) {
startVideoPlayback();
}
}
public void surfaceChanged(SurfaceHolder surfaceholder, int i, int j, int k) {
Log.d(TAG, "surfaceChanged called");
}
public void surfaceDestroyed(SurfaceHolder surfaceholder) {
Log.d(TAG, "surfaceDestroyed called");
}
public void surfaceCreated(SurfaceHolder holder) {
Log.d(TAG, "surfaceCreated called");
playVideo(extras);
}
#Override
protected void onPause() {
super.onPause();
releaseMediaPlayer();
doCleanUp();
}
#Override
protected void onDestroy() {
super.onDestroy();
releaseMediaPlayer();
doCleanUp();
}
private void releaseMediaPlayer() {
if (mMediaPlayer != null) {
mMediaPlayer.release();
mMediaPlayer = null;
}
}
private void doCleanUp() {
mVideoWidth = 0;
mVideoHeight = 0;
mIsVideoReadyToBePlayed = false;
mIsVideoSizeKnown = false;
}
private void startVideoPlayback() {
Log.v(TAG, "startVideoPlayback");
holder.setFixedSize(mVideoWidth, mVideoHeight);
mMediaPlayer.start();
}
}
As an alternative, I tried just using the default player like this:
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(aDirectory.getAbsolutePath())), "video/*");
startActivity(intent);
But it always plays the first video alphabetically in the folder instead of the one selected
