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。

官方文档地址：https://developer.qiniu.com/pili/sdk/3718/PLDroidMediaStreaming-quick-start
官方Demo地址：https://github.com/pili-engineering/PLDroidMediaStreaming
SDK地址：https://github.com/pili-engineering/PLDroidMediaStreaming/tree/master/releases
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

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.live.demo"><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.CAMERA" /><uses-permission android:name="android.permission.WAKE_LOCK" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-feature android:glEsVersion="0x00020000" android:required="true" /><applicationandroid:name=".StreamingApplication"android:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:roundIcon="@mipmap/ic_launcher_round"android:supportsRtl="true"android:theme="@style/AppTheme"><activity android:name=".Activity.MainActivity"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity><activityandroid:name="com.qiniu.pili.droid.streaming.screen.ScreenCaptureRequestActivity"android:theme="@android:style/Theme.Translucent.NoTitleBar"></activity><activity android:name=".Activity.AVStreamingActivity" /><activity android:name=".Activity.SWCameraStreamingActivity" /></application></manifest>

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 {@Overridepublic 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;@Overrideprotected 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);}@Overridepublic void onClick(View v) {new Thread(new Runnable() {@Overridepublic void run() {final String tlpath =   genPublishURL();
//                video_AudioIntent 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;}
}

主界面布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:gravity="center_horizontal"tools:context=".demo.Activity.MainActivity"><TextViewandroid:id="@+id/tv_start"android:text="开始推流"android:gravity="center"android:textSize="18sp"android:layout_marginTop="40dp"android:textColor="@color/textColorPrimary"android:background="@color/colorHeader"android:layout_width="160dp"android:layout_height="50dp" /></LinearLayout>

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
