七牛云直播SDK之推流端快速开发

前言

   七牛云直播SDK迭代快，但是官方文档跟不上迭代速度，导致快速开始这部分文档的还没更新，很多被废弃的类、方法还在文档中，本文是基于2.3.0版本进行的快速开发，由于是第一次接触直播，存在着许多不足欢迎批评指正。

1. 官方文档地址：https://developer.qiniu.com/pili/sdk/3718/PLDroidMediaStreaming-quick-start
2. 官方Demo地址：https://github.com/pili-engineering/PLDroidMediaStreaming
3. SDK地址：https://github.com/pili-engineering/PLDroidMediaStreaming/tree/master/releases
4. 本文代码地址：https://github.com/infoSafe/LiveBroadcastDemo

快速开始

•  创建项目（软编要求 MinimumSDK API 15 ； 硬编要求 MinimumSDK API 18）本文使用的是18
• 导入SDK，在 app/src/main 目录下创建 jniLibs 目录。将文件导入对应的目录（如下图）。

     

• 添加相关权限并注册 Activity

•  

• 添加 happy-dns 依赖（

  compile 'com.qiniu:happy-dns:0.2.8'

  ）

• 实现自己的 Application

  import android.app.Application;
  
  import com.qiniu.pili.droid.streaming.StreamingEnv;
  
  public class StreamingApplication extends Application {
      @Override
      public void onCreate() {
          super.onCreate();
          /**
           * init must be called before any other func
           */
          StreamingEnv.init(getApplicationContext());
      }
  }

   

• 创建主界面

  package com.live.demo.Activity;
  
  import android.app.Activity;
  import android.content.Intent;
  import android.os.Bundle;
  import android.view.View;
  import android.widget.TextView;
  
  import com.live.demo.R;
  import com.live.demo.Util.Util;
  
  import java.util.UUID;
  
  public class MainActivity extends Activity  implements View.OnClickListener{
  
      private static final String TAG = "MainActivity";
  
      private static final String GENERATE_STREAM_TEXT = "http://api-demo.qnsdk.com/v1/live/stream/";
  
      private TextView tv_start;
  
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          initView();
      }
  
  
      public void initView(){
          tv_start = findViewById(R.id.tv_start);
          tv_start.setOnClickListener(this);
      }
  
  
      @Override
      public void onClick(View v) {
          new Thread(new Runnable() {
              @Override
              public void run() {
                final String tlpath =   genPublishURL();
  //                video_Audio
                  Intent intent = new Intent(MainActivity.this, SWCameraStreamingActivity.class);
  //                传推流地址
                  intent.putExtra("stream_publish_url", tlpath);
                  startActivity(intent);
  
              }
          }).start();
      }
  
  
      /**
       * @author: 
       * @create at: 2018/11/13  13:01
       * @Description: 获取推流地址
       */
      private String genPublishURL() {
          String publishUrl = Util.syncRequest(GENERATE_STREAM_TEXT + UUID.randomUUID());
          return publishUrl;
      }
  }

推流界面布局

启动 APP 之后，当点击 开始推流，就可以开始推流了。

测试直播效果

1.下载播放端的Demo运行输入推流地址 ：https://github.com/pili-engineering/PLDroidPlayer

2.或者扫码下载播放app输入推流地址

推流地址获取方法

  手机运行app，as打印推流地址
