Ucloud直播云SDK的简单集成

来源：互联网发布：手机选购知乎编辑：程序博客网时间：2024/05/18 02:26

近段时间在做有关直播的项目，对ucloud的云直播sdk也有所了解，下面就来说说集成。

推流：

1.首先去ucloud官网下载最新的sdk,注意还有lib下面.so文件也要放到自己的项目中去。（目前只有armeabi-v7a的包，官方说很快会有其他包。注意：若项目中还用到其他.so，使用时lib下面的文件夹都要有相应的.so文件，否则会出现崩溃）。

2.布局文件:

<com.ucloud.live.widget.UAspectFrameLayout    android:id="@+id/container"    android:layout_gravity="center"    android:background="@color/color_progress"    android:layout_width="match_parent"    android:layout_height="match_parent"></com.ucloud.live.widget.UAspectFrameLayout>

3.java代码：

官方Demo中有不少类，这里我只讲重点部分

①初始化

protected EasyStreaming mEasyStreaming;protected UStreamingProfile mStreamingProfile;

//设置推流地址

第一个参数为推流地址的host,如publish3.cdn.ucloud.com.cn，第二个参数为id，整个推流即:rtmp://publish3.cdn.ucloud.com.cn/id

UStreamingProfile.Stream stream = new UStreamingProfile.Stream(rtmpPushStreamDomain, "ucloud/" + mSettings.getPusblishStreamId());mPreviewContainer.setShowMode(UAspectFrameLayout.Mode.FULL);//设置 上下文对象、显示的控件Id、视频编码类型、摄像头（前）、视频编码比特率，帧率等等mStreamingProfile = new UStreamingProfile.Builder()        .setContext(this)        .setPreviewContainerLayout(mPreviewContainer)        .setEncodeType(mSettings.getEncoderType())        .setCameraId(whichCamera)        .setResolution(UStreamingProfile.Resolution.RATIO_AUTO)        .setVideoBitrate(mSettings.getVideoBitRate())        .setVideoFrameRate(mSettings.getVideoFrameRate())        .setAudioBitrate(UStreamingProfile.AUDIO_BITRATE_NORMAL)        .setVideoCaptureOrientation(mSettings.getVideoCaptureOrientation())//UStreamingProfile.ORIENTATION_LANDSCAPE or UStreamingProfile.ORIENTATION_PORTRAIT        .setStream(stream).build();handleShowStreamingInfo(mStreamingProfile.getEncodeType());mEasyStreaming = UEasyStreaming.Factory.newInstance(mStreamingProfile);mEasyStreaming.addListener(this);②开始推流if (mEasyStreaming != null) {    mEasyStreaming.startRecording();}

注意：OnPause(),OnResum(),OnDestory()中要重写：
@Overrideprotected void onPause() {    super.onPause();    Log.e(TAG, "lifecycle->demo->activity->onPause");    //if UEasyStermaing no inited in activity onCreate method , you need call this method after inited -> function as camera stopPreivew()    mEasyStreaming.onPause();}@Overrideprotected void onResume() {    super.onResume();    Log.e(TAG, "lifecycle->demo->activity->onResume");    //if UEasyStermaing no inited in activity onCreate method, you need call this method after inited -> function as camera startPreivew()    mEasyStreaming.onResume();}@Overrideprotected void onDestroy() {    super.onDestroy();    if(mSettings.isOpenLogRecoder()) {        Log2FileUtil.getInstance().stopLog();    }    Log.e(TAG, "lifecycle->demo->activity->onDestroy");    mEasyStreaming.onDestroy();}

③停止推流
if (mEasyStreaming != null) {    mEasyStreaming.stopRecording();}

④其他设置
切换摄像头：
if (mEasyStreaming != null) {    mEasyStreaming.switchCamera();}

打开、关闭闪光灯
 if (mEasyStreaming != null) {    mEasyStreaming.toggleFlashMode();}

注意：本文从官方Demo中抽出重点，集成时请结合官方Demo和文档。
