Android平台RTSP|RTMP直播播放器技术接入说明

技术背景

大牛直播SDK自2015年发布RTSP、RTMP直播播放模块，迭代从未停止，SmartPlayer功能强大、性能强劲、高稳定、超低延迟、超低资源占用。无需赘述，全自研内核，行业内一致认可的跨平台RTSP、RTMP直播播放器。本文以Android平台为例，介绍下如何集成RTSP、RTMP播放模块。

技术对接

系统要求

SDK支持Android5.1及以上版本；
支持的CPU架构：armv7, arm64, x86, x86_64。

准备工作

确保SmartPlayerJniV2.java放到com.daniulive.smartplayer包名下(可在其他包名下调用)；
Smartavengine.jar加入到工程；
拷贝SmartPlayerV2\app\src\main\jniLibs\armeabi-v7a、 SmartPlayerV2\app\src\main\jniLibs\arm64-v8a、SmartPlayerV2\app\src\main\jniLibs\x86和SmartPlayerV2\app\src\main\jniLibs\x86_64 下 libSmartPlayer.so到工程；
AndroidManifast.xml添加相关权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >
</uses-permission>
<uses-permission android:name="android.permission.INTERNET" >
</uses-permission>
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

Load相关so：

static {  System.loadLibrary("SmartPlayer");
}

build.gradle配置32/64位库：

splits {abi {enable truereset()// Specifies a list of ABIs that Gradle should create APKs forinclude 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64' //select ABIs to build APKs for// Specify that we do not want to also generate a universal APK that includes all ABIsuniversalApk true}
}

如需集成到自己系统测试，请用大牛直播SDK的app name，授权版按照授权app name正常使用即可；
如何改app-name，strings.xml做以下修改：

<string name="app_name">SmartPlayerSDKDemo</string>

接口设计

Android RTSP\|RTMP播放端SDK接口详解
调用描述		接口	接口描述
最先调用，如成功返回播放实例		SmartPlayerOpen	player初始化，设置上下文信息，返回player句柄
Event回调		SetSmartPlayerEventCallbackV2	设置event callback
硬解码设置（H.264）		SetSmartPlayerVideoHWDecoder	设置是否用H.264硬解码播放，如硬解码不支持，自动适配到软解码
硬解码设置（H.265）		SetSmartPlayerVideoHevcHWDecoder	设置是否用H.265硬解码播放，如硬解码不支持，自动适配到软解码
视频画面填充模式		SmartPlayerSetRenderScaleMode	设置视频画面的填充模式，如填充整个view、等比例填充view，如不设置，默认填充整个view
设置SurfaceView模式下render类型		SmartPlayerSetSurfaceRenderFormat	设置SurfaceView模式下(NTRenderer.CreateRenderer第二个参数传false的情况)，render类型 0: RGB565格式，如不设置，默认此模式; 1: ARGB8888格式
设置SurfaceView模式下抗锯齿效果		SmartPlayerSetSurfaceAntiAlias	设置SurfaceView模式下(NTRenderer.CreateRenderer第二个参数传false的情况)，抗锯齿效果，注意：抗锯齿模式开启后，可能会影像性能，请慎用
设置播放的surface		SmartPlayerSetSurface	设置播放的surface，如果为null，则播放纯音频
设置视频硬解码下Mediacodec自行绘制模式		SmartPlayerSetHWRenderMode	此种模式下，硬解码兼容性和效率更好，回调YUV/RGB、快照和图像等比例缩放功能将不可用
更新硬解码surface		SmartPlayerUpdateHWRenderSurface	设置更新硬解码surface
音频回调	YUV/RGB	SmartPlayerSetExternalRender	提供解码后YUV/RGB数据接口，供用户自己render或进一步处理(如视频分析)
音频回调	Audio	SmartPlayerSetExternalAudioOutput	回调audio数据到上层（供二次处理之用）
audio输出类型		SmartPlayerSetAudioOutputType	如果use_audiotrack设置为0，将会自动选择输出设备，如果设置为1，使用audiotrack模式，一对一回音消除模式下，请选用audiotrack模式
Video输出类型		NTRenderer.CreateRenderer（上层demo内）	第二个参数，如果是true，用openGLES绘制，false则用默认surfaceView
播放模式	缓冲时间设置	SmartPlayerSetBuffer	设置播放端缓存数据buffer，单位：毫秒，如不需buffer，设置为0
	首屏秒开	SmartPlayerSetFastStartup	设置快速启动后，如果CDN缓存GOP，实现首屏秒开
	低延迟模式	SmartPlayerSetLowLatencyMode	针对类似于直播娃娃机等期待超低延迟的使用场景，超低延迟播放模式下，延迟可达到200~400ms
	快速切换URL	SmartPlayerSwitchPlaybackUrl	快速切换播放url，快速切换时，只换播放source部分，适用于不同数据流之间，快速切换（如娃娃机双摄像头切换或高低分辨率流切换）
RTSP TCP/UDP模式设置		SmartPlayerSetRTSPTcpMode	设置RTSP TCP/UDP模式，如不设置，默认UDP模式
RTSP超时时间设置		SmartPlayerSetRTSPTimeout	设置RTSP超时时间，timeout单位为秒，必须大于0
设置RTSP TCP/UDP自动切换		SmartPlayerSetRTSPAutoSwitchTcpUdp	对于RTSP来说，有些可能支持rtp over udp方式，有些可能支持使用rtp over tcp方式为了方便使用，有些场景下可以开启自动尝试切换开关, 打开后如果udp无法播放，sdk会自动尝试tcp, 如果tcp方式播放不了,sdk会自动尝试udp.
设置RTSP用户名和密码		SetRTSPAuthenticationInfo	如果RTSP URL已包含用户名和密码, 此接口设置的用户名和密码将无效. 就是说要用这个接口设置的用户名和密码去做认证, RTSP URL不能包含用户名和密码.
实时静音		SmartPlayerSetMute	实时静音
设置播放音量		SmartPlayerSetAudioVolume	播放端音量实时调节，范围[0,100]，0时为静音，100为原始流数据最大音量
设置是否禁用 Enhanced RTMP		DisableEnhancedRTMP	disable enhanced RTMP, SDK默认是开启enhanced RTMP的
实时截图		CaptureImage	支持JPEG和PNG两种格式
视频镜像旋转	旋转	SmartPlayerSetRotation	设置顺时针旋转, 注意除了0度之外，其他角度都会额外消耗性能，当前支持 0度，90度, 180度, 270度旋转
	水平反转	SmartPlayerSetFlipHorizontal	设置视频水平反转
	垂直反转	SmartPlayerSetFlipVertical	设置视频垂直反转
设置URL		SmartPlayerSetUrl	设置需要播放或录像的RTMP/RTSP url

接口调用详解

本文以大牛直播SDK Android平台SmartPlayerV2为例，播放之前，设置初始化参数配置（软解还是硬解、buffer time等）和需要播放的RTSP或RTMP URL，点开始播放即可。

onCreate()时，先new SmartPlayerJniV2()：

/** SmartPlayer.java* Author: daniusdk.com*/
@Override
protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_smart_player);...libPlayer = new SmartPlayerJniV2();myContext = this.getApplicationContext();
}

开始播放、停止播放实现，开始播放的时候，调用InitAndSetConfig()，完成常规参数初始化，然后调用仅播放相关的其他接口。

btnStartStopPlayback.setOnClickListener(new Button.OnClickListener() {// @Overridepublic void onClick(View v) {if (isPlaying) {Log.i(TAG, "Stop playback stream++");int iRet = libPlayer.SmartPlayerStopPlay(playerHandle);if (iRet != 0) {Log.e(TAG, "Call SmartPlayerStopPlay failed..");return;}btnHardwareDecoder.setEnabled(true);btnLowLatency.setEnabled(true);if (!isRecording) {btnPopInputUrl.setEnabled(true);btnSetPlayBuffer.setEnabled(true);btnFastStartup.setEnabled(true);btnRecoderMgr.setEnabled(true);libPlayer.SmartPlayerClose(playerHandle);playerHandle = 0;}isPlaying = false;btnStartStopPlayback.setText("开始播放 ");if (is_enable_hardware_render_mode && sSurfaceView != null) {sSurfaceView.setVisibility(View.GONE);sSurfaceView.setVisibility(View.VISIBLE);}Log.i(TAG, "Stop playback stream--");} else {Log.i(TAG, "Start playback stream++");if (!isRecording) {InitAndSetConfig();}// 如果第二个参数设置为null，则播放纯音频libPlayer.SmartPlayerSetSurface(playerHandle, sSurfaceView);libPlayer.SmartPlayerSetRenderScaleMode(playerHandle, 1);//int render_format = 1;//libPlayer.SmartPlayerSetSurfaceRenderFormat(playerHandle, render_format);//int is_enable_anti_alias = 1;//libPlayer.SmartPlayerSetSurfaceAntiAlias(playerHandle, is_enable_anti_alias);if (isHardwareDecoder && is_enable_hardware_render_mode) {libPlayer.SmartPlayerSetHWRenderMode(playerHandle, 1);}// External Render test//libPlayer.SmartPlayerSetExternalRender(playerHandle, new RGBAExternalRender(imageSavePath));//libPlayer.SmartPlayerSetExternalRender(playerHandle, new I420ExternalRender(imageSavePath));libPlayer.SmartPlayerSetUserDataCallback(playerHandle, new UserDataCallback());//libPlayer.SmartPlayerSetSEIDataCallback(playerHandle, new SEIDataCallback());libPlayer.SmartPlayerSetAudioOutputType(playerHandle, 1);if (isMute) {libPlayer.SmartPlayerSetMute(playerHandle, isMute ? 1: 0);}if (isHardwareDecoder) {int isSupportHevcHwDecoder = libPlayer.SetSmartPlayerVideoHevcHWDecoder(playerHandle, 1);int isSupportH264HwDecoder = libPlayer.SetSmartPlayerVideoHWDecoder(playerHandle, 1);Log.i(TAG, "isSupportH264HwDecoder: " + isSupportH264HwDecoder + ", isSupportHevcHwDecoder: " + isSupportHevcHwDecoder);}libPlayer.SmartPlayerSetLowLatencyMode(playerHandle, isLowLatency ? 1: 0);libPlayer.SmartPlayerSetFlipVertical(playerHandle, is_flip_vertical ? 1 : 0);libPlayer.SmartPlayerSetFlipHorizontal(playerHandle, is_flip_horizontal ? 1 : 0);libPlayer.SmartPlayerSetRotation(playerHandle, rotate_degrees);libPlayer.SmartPlayerSetAudioVolume(playerHandle, curAudioVolume);int iPlaybackRet = libPlayer.SmartPlayerStartPlay(playerHandle);if (iPlaybackRet != 0) {Log.e(TAG, "Call SmartPlayerStartPlay failed..");return;}btnStartStopPlayback.setText("停止播放 ");btnPopInputUrl.setEnabled(false);btnPopInputKey.setEnabled(false);btnSetPlayBuffer.setEnabled(false);btnLowLatency.setEnabled(false);btnFastStartup.setEnabled(false);btnRecoderMgr.setEnabled(false);isPlaying = true;Log.i(TAG, "Start playback stream--");}}
});

由于RTSP、RTMP播放模块，除了常规的直播播放外，也可能录像、或者实时拉流转发到RTMP服务器或轻量级RTSP服务，所以，和录像、转发相关的播放端基础参数配置，放到InitAndSetConfig()实现：

private void InitAndSetConfig() {playerHandle = libPlayer.SmartPlayerOpen(myContext);if (playerHandle == 0) {Log.e(TAG, "surfaceHandle with nil..");return;}libPlayer.SetSmartPlayerEventCallbackV2(playerHandle,new EventHandeV2());libPlayer.SmartPlayerSetBuffer(playerHandle, playBuffer);// set report download speed(默认2秒一次回调 用户可自行调整report间隔)libPlayer.SmartPlayerSetReportDownloadSpeed(playerHandle, 1, 2);libPlayer.SmartPlayerSetFastStartup(playerHandle, isFastStartup ? 1 : 0);//设置RTSP超时时间int rtsp_timeout = 10;libPlayer.SmartPlayerSetRTSPTimeout(playerHandle, rtsp_timeout);//设置RTSP TCP/UDP模式自动切换int is_auto_switch_tcp_udp = 1;libPlayer.SmartPlayerSetRTSPAutoSwitchTcpUdp(playerHandle, is_auto_switch_tcp_udp);libPlayer.SmartPlayerSaveImageFlag(playerHandle, 1);// It only used when playback RTSP stream..// libPlayer.SmartPlayerSetRTSPTcpMode(playerHandle, 1);// playbackUrl = "rtmp://localhost:1935/live/stream1";if (playbackUrl == null) {Log.e(TAG, "playback URL with NULL...");return;}libPlayer.SmartPlayerSetUrl(playerHandle, playbackUrl);// try_set_rtsp_url(playbackUrl);
}

EventHandle播放端事件回调处理，是底层状态反馈非常重要的媒介，除了网络状态、buffering状态回调外、还有录像状态、快照状态等回调：

class EventHandeV2 implements NTSmartEventCallbackV2 {@Overridepublic void onNTSmartEventCallbackV2(long handle, int id, long param1,long param2, String param3, String param4, Object param5) {String player_event = "";switch (id) {case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_STARTED:player_event = "开始..";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_CONNECTING:player_event = "连接中..";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_CONNECTION_FAILED:player_event = "连接失败..";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_CONNECTED:player_event = "连接成功..";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_DISCONNECTED:player_event = "连接断开..";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_STOP:player_event = "停止播放..";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_RESOLUTION_INFO:player_event = "分辨率信息: width: " + param1 + ", height: " + param2;break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_NO_MEDIADATA_RECEIVED:player_event = "收不到媒体数据，可能是url错误..";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_SWITCH_URL:player_event = "切换播放URL..";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_CAPTURE_IMAGE:player_event = "快照: " + param1 + " 路径：" + param3;if (param1 == 0)player_event = player_event + ", 截取快照成功";elseplayer_event = player_event + ", 截取快照失败";if (param4 != null && !param4.isEmpty())player_event += (", user data:" + param4);break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_RECORDER_START_NEW_FILE:player_event = "[record]开始一个新的录像文件 : " + param3;break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_ONE_RECORDER_FILE_FINISHED:player_event = "[record]已生成一个录像文件 : " + param3;break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_START_BUFFERING:Log.i(TAG, "Start Buffering");break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_BUFFERING:Log.i(TAG, "Buffering:" + param1 + "%");break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_STOP_BUFFERING:Log.i(TAG, "Stop Buffering");break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_DOWNLOAD_SPEED:player_event = "download_speed:" + param1 + "Byte/s" + ", "+ (param1 * 8 / 1000) + "kbps" + ", " + (param1 / 1024)+ "KB/s";break;case NTSmartEventID.EVENT_DANIULIVE_ERC_PLAYER_RTSP_STATUS_CODE:Log.e(TAG, "RTSP error code received, please make sure username/password is correct, error code:" + param1);player_event = "RTSP error code:" + param1;break;}if (player_event.length() > 0) {Log.i(TAG, player_event);Message message = new Message();message.what = PLAYER_EVENT_MSG;message.obj = player_event;handler.sendMessage(message);}}
}

如果RTSP、RTMP流需要录像：

btnStartStopRecorder.setOnClickListener(new Button.OnClickListener() {// @Overridepublic void onClick(View v) {if (isRecording) {int iRet = libPlayer.SmartPlayerStopRecorder(playerHandle);if (iRet != 0) {Log.e(TAG, "Call SmartPlayerStopRecorder failed..");return;}if (!isPlaying) {btnPopInputUrl.setEnabled(true);btnSetPlayBuffer.setEnabled(true);btnFastStartup.setEnabled(true);btnRecoderMgr.setEnabled(true);libPlayer.SmartPlayerClose(playerHandle);playerHandle = 0;}btnStartStopRecorder.setText(" 开始录像");isRecording = false;} else {Log.i(TAG, "onClick start recorder..");if (!isPlaying) {InitAndSetConfig();}ConfigRecorderFunction();int startRet = libPlayer.SmartPlayerStartRecorder(playerHandle);if (startRet != 0) {Log.e(TAG, "Failed to start recorder.");return;}btnPopInputUrl.setEnabled(false);btnSetPlayBuffer.setEnabled(false);btnFastStartup.setEnabled(false);btnRecoderMgr.setEnabled(false);isRecording = true;btnStartStopRecorder.setText("停止录像");}}
});

其中，录像参数配置选项设置如下，除了下面演示接口外，还可以设置仅录视频或音频：

void ConfigRecorderFunction() {if (libPlayer != null) {int is_rec_trans_code = 1;libPlayer.SmartPlayerSetRecorderAudioTranscodeAAC(playerHandle, is_rec_trans_code);if (recDir != null && !recDir.isEmpty()) {int ret = libPlayer.SmartPlayerCreateFileDirectory(recDir);if (0 == ret) {if (0 != libPlayer.SmartPlayerSetRecorderDirectory(playerHandle, recDir)) {Log.e(TAG, "Set recoder dir failed , path:" + recDir);return;}if (0 != libPlayer.SmartPlayerSetRecorderFileMaxSize(playerHandle, 200)) {Log.e(TAG,"SmartPublisherSetRecorderFileMaxSize failed.");return;}} else {Log.e(TAG, "Create recorder dir failed, path:" + recDir);}}}
}

如需播放过程中实时截图：

btnCaptureImage.setOnClickListener(new Button.OnClickListener() {@SuppressLint("SimpleDateFormat")public void onClick(View v) {if (0 == playerHandle)return;if (null == capture_image_date_format_)capture_image_date_format_ = new SimpleDateFormat("yyyyMMdd_HHmmss_SSS");String timestamp = capture_image_date_format_.format(new Date());String imageFileName = timestamp;String image_path = imageSavePath + "/" + imageFileName;int quality;boolean is_jpeg = true;if (is_jpeg) {image_path += ".jpeg";quality = 100;}else {image_path += ".png";quality = 100;}int capture_ret = libPlayer.CaptureImage(playerHandle,is_jpeg?0:1, quality, image_path, "test cix");Log.i(TAG, "capture image ret:" + capture_ret + ", file:" + image_path);}
});

如需对视频view做水平、垂直翻转或旋转：

btnFlipVertical.setOnClickListener(new Button.OnClickListener() {public void onClick(View v) {is_flip_vertical = !is_flip_vertical;if (is_flip_vertical) {btnFlipVertical.setText("取消反转");} else {btnFlipVertical.setText("垂直反转");}if (playerHandle != 0) {libPlayer.SmartPlayerSetFlipVertical(playerHandle,is_flip_vertical ? 1 : 0);}}
});btnFlipHorizontal.setOnClickListener(new Button.OnClickListener() {public void onClick(View v) {is_flip_horizontal = !is_flip_horizontal;if (is_flip_horizontal) {btnFlipHorizontal.setText("取消反转");} else {btnFlipHorizontal.setText("水平反转");}if (playerHandle != 0) {libPlayer.SmartPlayerSetFlipHorizontal(playerHandle,is_flip_horizontal ? 1 : 0);}}
});btnRotation.setOnClickListener(new Button.OnClickListener() {public void onClick(View v) {rotate_degrees += 90;rotate_degrees = rotate_degrees % 360;if (0 == rotate_degrees) {btnRotation.setText("旋转90度");} else if (90 == rotate_degrees) {btnRotation.setText("旋转180度");} else if (180 == rotate_degrees) {btnRotation.setText("旋转270度");} else if (270 == rotate_degrees) {btnRotation.setText("不旋转");}if (playerHandle != 0) {libPlayer.SmartPlayerSetRotation(playerHandle,rotate_degrees);}}
});

onDestroy() 的时候，停掉播放、录像、释放播放端实例句柄：

@Override
protected void onDestroy() {Log.i(TAG, "Run into activity destory++");if (playerHandle != 0) {if (isPlaying) {libPlayer.SmartPlayerStopPlay(playerHandle);}if (isRecording) {libPlayer.SmartPlayerStopRecorder(playerHandle);}libPlayer.SmartPlayerClose(playerHandle);playerHandle = 0;}super.onDestroy();finish();System.exit(0);
}

以上是大概的流程，如果需要播放多实例，可以做个简单的封装，多实例效果如下：

LibPlayerWrapper.java参考封装代码如下，如需额外功能，只要按照设计框架，添加进去即可：
