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;@OverrIDepublic 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);    }}@OverrIDeprotected voID onPause() {    mVIDeoVIEw.pause();    super.onPause();}@OverrIDeprotected 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@OverrIDepublic 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.
