如何在Android应用程序中播放实时流媒体？

Question

I want to make application for cricket live streaming. I want to know following things :

1. From where I can found the links to play cricket streaming ?
2. Which type of links are these ?
3. Is there any player to play this type of videos ?

Currently, I have implemented web page but I am looking for other alternative.

Below is my code :

    link1 = (RelativeLayout) findViewById(R.id.link1);
    link2 = (RelativeLayout) findViewById(R.id.link2);
    link3 = (RelativeLayout) findViewById(R.id.link3);
    link4 = (RelativeLayout) findViewById(R.id.link4);
    link5 = (RelativeLayout) findViewById(R.id.link5);
    link6 = (RelativeLayout) findViewById(R.id.link6);
    link7 = (RelativeLayout) findViewById(R.id.link7);
    link1.setOnClickListener(this);
    link2.setOnClickListener(this);
    link3.setOnClickListener(this);
    link4.setOnClickListener(this);
    link5.setOnClickListener(this);
    link6.setOnClickListener(this);
    link7.setOnClickListener(this);
}

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.link1:
         linkFunction("http://changevssame.blogspot.com/2014/03/willow-cricket-hd-live-streaming.html");

        break;
    case R.id.link2:
        linkFunction("http://changevssame.blogspot.com/2014/03/foxsports-live-streaming.html");
        break;
    case R.id.link3:
        linkFunction("http://changevssame.blogspot.com/2014/03/sky-sports-live-streaming.html");
        break;
    case R.id.link4:
        linkFunction("http://changevssame.blogspot.com/2014/03/ten-sports-live-streaming.html");
        break;
    case R.id.link5:
        linkFunction("http://changevssame.blogspot.com/2014/03/star-cricket.html");
        break;
    case R.id.link6:
        linkFunction("http://changevssame.blogspot.com/2014/03/icc-t20-world-cup-2014-live-streaming.html");
        break;
    case R.id.link7:
        linkFunction("http://changevssame.blogspot.com/2014/03/ptv-sports.html");
        break;

    default:
        break;
    }

Answer 1

I will try to answer your questions but there are many fundamentals you've got to learn in order to build up a successful Streaming Application.

 1. From where I can found the links to play cricket streaming ? 

No idea, but this is not a SO standard question anyway.

 2. Which type of links are these ? 

IF you mean live streaming links, there are many types but mostly they are either HLS or RTSP. HLS links are simple HTTP links that often end with a ".m3u8" postfix. (eg " http://somewebsite.com/streams/hls_stream_video.m3u8 ")

RTSP links on the other hand, have a format like this: "rtsp://somewebsite.com/streams/an_rtsp_stream.mp4"

 3. Is there any player to play this type of videos ? 

Absolutely. You can do so by any means. I'm not exactly sure by "a player" whether you mean Android API player or third-party player applications. So I'll cover both cases for you and future passengers.

I) Android API: You can do so with the help of a MediaController , a MediaPlayer and a SurafceView . The latter two are also available in a unit entity known as VideoView . There is a code in the answer below, you can use that. But Be aware of two key points:

Ia) Using MediaPlayer is harder to implement but gives you more detailed control compared to VideoView .

Ib) If you use some code similar to the below answer Never call prepare() for network streams. Always prepareAsync() . And Always call setAudioStreamType() before prepareAsync. Otherwise you will face transient sync issues between Audio and Video when seeking on the progressbar.

II) Player Application: I have done streaming with MXPlayer and it works great.

There are some considerations to take before starting:

What protocol to choose?

Assuming you are targeting Android, I can advice you to narrow your choices down to HLS and RTSP. You need to study them well before making a decision. But to give you a hint. HLS is preferred when functioning on lower Bandwidths.

There are many other topics like whether to choose UDP/TCP , IP-Multicast/Broadcast and so on...

Go and visit this tutorial . This is the most complete zero-to-hero guide in my opinion.

Since SO lacks a thorough post on Video Streaming , maybe I will extend my answer on demand.

Follow this link :

Android Video Streaming

Below code works for me :

public static void getVideoFromHttp(String urlPath) {

try {
// Start the MediaController
MediaController mediacontroller = new MediaController(mContext);
mediacontroller.setAnchorView(mVideoview);
// Get the URL from String VideoURL
Uri mVideo = Uri.parse(urlPath);
mVideoview.setMediaController(mediacontroller);
mVideoview.setVideoURI(mVideo);

} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();

}

mVideoview.requestFocus();
mVideoview.setOnPreparedListener(new OnPreparedListener() {
// Close the progress bar and play the video
public void onPrepared(MediaPlayer mp) {
mVideoview.start();

}
});

mVideoview.setOnCompletionListener(new OnCompletionListener() {

public void onCompletion(MediaPlayer mp) {

}
});

}

Try this:

private void playLive(String path){

   try {
        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);
      }
}
