在android中播放m3u8视频

Question

我想直播视频,它是m3u8格式.所以我尝试了下面的代码

public class StreamingPlayer extends Activity implements
OnBufferingUpdateListener, OnCompletionListener,
OnPreparedListener, OnVideoSizeChangedListener, SurfaceHolder.Callback{

    private static final String TAG = StreamingPlayer.class.getSimpleName();
    private int mVideoWidth;
    private int mVideoHeight;
    private MediaPlayer mMediaPlayer;
    private SurfaceView mPreview;
    private SurfaceHolder holder;
    private String path;

    private boolean mIsVideoSizeKnown = false;
    private boolean mIsVideoReadyToBePlayed = false;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mediaplayer_2);
        mPreview = (SurfaceView) findViewById(R.id.surface);
        holder = mPreview.getHolder();
        holder.addCallback(this);
        holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
    }

    private void playVideo() {
        doCleanUp();
        try {

            /*
             * 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 = "httplive://xboodangx.api.channel.livestream.com/3.0/playlist.m3u8";

            if (path == "") {
                // Tell the user to provide a media file URL.
                Toast
                .makeText(
                        this,
                        "Please edit MediaPlayerDemo_Video Activity,"
                        + " and set the path variable to your media file URL.",
                        Toast.LENGTH_LONG).show();
            } 

            Log.e("PATH", "Path = " + path);
            // Create a new media player and set the listeners
            mMediaPlayer = new MediaPlayer();
            mMediaPlayer.setDataSource(path);
            mMediaPlayer.setDisplay(holder);
                    mMediaPlayer.setOnBufferingUpdateListener(this);
                    mMediaPlayer.setOnPreparedListener(this);
            mMediaPlayer.prepare();
            mMediaPlayer.setOnCompletionListener(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();

    }

    @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();
    }


}

在logcat它显示onBufferingUpdate percent:100但我看不到视频.

音频正在工作,但突然间它被击中了.

我尝试了这个视频链接http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8它正在工作.但我的视频链接不起作用,我改变httplive://... instead of http://但没有用.

我看到这个答案也是Android视频流mms和m3u8.

在上面的链接中显示视频无法播放的消息.

Answer 1

该视频存在于http://www.livestream.com.在这里有Mobile Api用于直播.

Api是:

http://www.livestream.com/userguide/index.php?title=Mobile_API#How_to_get_mobile_compatible_clips_from_a_channel.27s_library

在上面的链接中,有完整的移动兼容信息.从通道获取rtsp链接以使用此链接

http://xproshowcasex.channel-api.livestream-api.com/2.0/getstream

替换您的频道名称而不是proshowcase.然后获得所有移动兼容的网址,如iPhone,Android,黑莓等,

使用该网址,您可以使用视频视频或媒体播放器在Android中流式传输视频.

有关更多信息,请阅读Mobile Api链接.

如果有人遇到同样的问题,我希望这个答案对你有帮助.

祝你好运.

Answer 2

播放流没问题:

videoView1.setVideoPath("http://***.net/livedemo/_definst_/stream3.stream/playlist.m3u8?wowzasessionid=773395207");
videoView1.start();

关于消息:

视频无法播放

也许您需要为Manifest文件添加权限:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
