使用Vitamio Library的电视盒上的Android VideoView质量太差了
作者:互联网
通过实施Vitamio库进行实时流式传输,努力为G-Box提供更好的质量.
在代码中使用了具有.mp4视频的示例在线视频URL.但是当我们在下载后在Media Player中播放它时,效果很好,而当我通过在线流进行尝试时,质量会很差.
以下是在视频视图上播放视频的代码.
public class VideoViewDemo extends Activity {
/**
* TODO: Set the path variable to a streaming video URL or a local media file
* path.
*/
private String path = "";
private VideoView mVideoView;
private ProgressDialog progDailog;
ProgressDialog progressDialog=null;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
if (!LibsChecker.checkVitamioLibs(this))
return;
setContentView(R.layout.videoview);
mVideoView = (VideoView) findViewById(R.id.surface_view);
path = "http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4";
if (path == "") {
// Tell the user to provide a media file URL/path.
Toast.makeText(VideoViewDemo.this, "Please edit
VideoViewDemo Activity, and set path" +
" variable to your media file URL/path", Toast.LENGTH_LONG).show();
return;
} else {
/*
* Alternatively,for streaming media you can use
* mVideoView.setVideoURI(Uri.parse(URLstring));
*/
mVideoView.setVideoPath(path);
mVideoView.setVideoQuality(MediaPlayer.VIDEOQUALITY_HIGH);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
progDailog = ProgressDialog.show(this, "Please wait ...",
"Retrieving data ...", true);
progDailog.setCancelable(true);
mVideoView.setOnPreparedListener(
new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
// optional need Vitamio 4.0
//mediaPlayer.setPlaybackSpeed(1.0f);
progDailog.dismiss();
}
});
mVideoView.setOnBufferingUpdateListener(
new OnBufferingUpdateListener() {
@Override
public void onBufferingUpdate(MediaPlayer arg0, int arg1) {
}
});
//mediaPlayer.setPlaybackSpeed(1.0f);
}
}
@Override
protected void onPause() {
mVideoView.pause();
super.onPause();
}
@Override
protected void onResume() {
mVideoView.resume();
progDailog.show();
super.onResume();
}
}
您的即时回应将对我有很大帮助
解决方法:
毫无疑问,Vitamio是一个非常好的图书馆,涵盖了与视频流有关的所有错误.
抱歉地说,但是Vitamio支持团队对我非常失望.我在论坛上发布了问题,但没有收到并反馈.
最后,我只是通过对提供的来源进行矿工更改来找到解决问题的方法.
enter code here@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
if (!LibsChecker.checkVitamioLibs(this))
return;
setContentView(R.layout.mediaplayer_2);
mPreview = (SurfaceView) findViewById(R.id.surface);
holder = mPreview.getHolder();
holder.addCallback(this);
//holder.setFormat(PixelFormat.RGBA_8888);
holder.setFormat(PixelFormat.RGBX_8888);
extras = getIntent().getExtras();
}
private void playVideo(Integer Media) {
doCleanUp();
Log.e(TAG, "Value Received: " + Media);
try {
switch (Media) {
case LOCAL_VIDEO:
/*
* TODO: Set the path variable to a local media file path.
*/
path = "";
path = Environment.getExternalStorageDirectory() + "/big_buck_bunny.mp4";
Log.e(TAG, "PATH = : " + path);
if (path == "") {
// Tell the user to provide a media file URL.
Toast.makeText(MediaPlayerDemo_Video.this, "Please edit MediaPlayerDemo_Video
Activity, " + "and set the path variable to your media file path."
+ " Your media file must be stored on sdcard.", Toast.LENGTH_LONG).show();
return;
}
break;
case STREAM_VIDEO:
/*
* TODO: Set path variable to progressive streamable mp4 or
* 3gpp format URL. Http protocol should be used.
* Mediaplayer can only play "progressive streamable
* contents" which basically means: 1. the movie atom has to
* precede all the media data atoms. 2. The clip has to be
* reasonably interleaved.
*
*/
path = "http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4";
if (path == "") {
// Tell the user to provide a media file URL.
Toast.makeText(MediaPlayerDemo_Video.this, "Please edit MediaPlayerDemo_Video
Activity," + " and set the path variable to your media file URL.",
Toast.LENGTH_LONG).show();
return;
}
break;
}
// Create a new media player and set the listeners
mMediaPlayer = new MediaPlayer(this);
mMediaPlayer.setVideoQuality(MediaPlayer.VIDEOQUALITY_HIGH);
mMediaPlayer.setDataSource(path);
mMediaPlayer.setDisplay(holder);
mMediaPlayer.prepare();
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setOnVideoSizeChangedListener(this);
mMediaPlayer.getMetadata();
setVolumeControlStream
(AudioManager.STREAM_MUSIC);
//mMediaPlayer.setVideoQuality
(io.vov.vitamio.MediaPlayer.VIDEOQUALITY_HIGH);
} catch (Exception e) {
Log.e(TAG, "error: " + e.getMessage(), e);
}
}
示例源中有一个文件名为“ MediaPlayerDemo_Video.java”
替换以下行
holder.setFormat(PixelFormat.RGBA_8888);
随着以下
holder.setFormat(PixelFormat.RGBX_8888);
这将解决整个问题.
