我希望直播视频,并采用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中显示onBufferingUpdate percent:100
但我看不到视频。
音频正在运转,但突然间它被击中了。
我试过这个视频链接http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8它正在运行。但是我的视频链接无效,我更改了httplive://... instead of http://
但没有用。
我也看到了这个答案Android video stream mms and m3u8。
在上面的链接中显示视频无法播放的消息。

该视频已存在于http://www.livestream.com中。在这里有Mobile Api用于直播。
Api是:
在上面的链接中,有完整的移动兼容信息。要从频道获取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网址,如iPhone,Android,Blackberry等,
使用该网址,您可以使用视频观看或媒体播放器在Android中流式传输视频。
有关详细信息,请阅读Mobile Api链接。
如果有人遇到同样的问题,我希望这个答案能帮到你。
祝你好运。
答案 1 :(得分:6)
播放视频流没问题:
videoView1.setVideoPath("http://***.net/livedemo/_definst_/stream3.stream/playlist.m3u8?wowzasessionid=773395207");
videoView1.start();
关于消息:
无法播放视频
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"/>
答案 2 :(得分:1)
我认为你应该这样做:
mMediaPlayer.setOnPreparedListener(this);
在致电prepare()
答案 3 :(得分:1)
您是否尝试通过网络浏览器直接播放与原生播放器的链接? 如果您无法使用本机播放器播放,则表示您当前的Android版本不支持您的文件。 HTTP Live Streaming格式可能具有一些Android不能很好支持的特性,而它可以在IOS上播放。
答案 4 :(得分:0)
我尝试了超过6个月的m3u8视频格式并没有成功。它正在我的iPhone应用程序和本机应用程序中播放。我的流媒体服务器是Red5,它没有RTSP插件。它提供了RTMP流媒体,无法在Android中进行流式传输。我等了一年才获得支持RTSP流媒体的操作系统,但谷歌没有。我仍然使用带有Flash播放器的网络视图来传输实时视频(它没有太多清晰度)。我很遗憾地向我的客户说这个并继续搜索在Android默认播放器中播放实时流。
我认为您的视频网址可能不是RTSP。

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_vv);//***************
myVideoView = (VideoView)this.findViewById(R.id.myVideoView);
MediaController mc = new MediaController(this);
myVideoView.setMediaController(mc);
urlStream = "http://jorgesys.net/i/irina_delivery@117489/master.m3u8";
runOnUiThread(new Runnable() {
@Override
public void run() {
myVideoView.setVideoURI(Uri.parse(urlStream));
}
});
}
}
我见过很多人在玩.M3U8时遇到问题,这取决于用于流媒体的编解码器以及与设备的兼容性,例如我的.m3u8文件只支持屏幕为1200 x800的设备。更高。
