本篇文章分享web实时预览功能开发 java 海康sdk nvr，对你有帮助的话记得收藏一下，看Java资料网收获更多编程知识
1.实时视频流解决方案
目录
1.前端调用后台接口，
2.后台接口调用海康sdk开启具体的摄像头监听，获取摄像头实时流数据
3.建立管道，海康sdk监听线程和javacv推流线程共享管道
4.sdk线程向管道输出流写数据，javacv推流线程向rtmp发送管道数据。即sdk生产者，javacv是消费者
5.nginx+rtmp+flv模块接收到视频流，可以通过http的路径在浏览器访问
前端->后台->海康sdk—>管道->javacv->nginx+rtmp+flv->http路径
2.步骤
1.搭建rtmp+flv服务器
windows系统下，自己编译比较麻烦，这边有大佬编译好的windows中obs+nginx-http-flv-module的流媒体服务搭建_windows nginx集成http-flv_OneCodeSolvesAll的博客-CSDN博客个人编译好的：链接：https://pan.baidu.com/s/1XKkyYvK5W6yZA1w2mPaAfg
提取码：3ug6
linux环境下，下载nginx-http-flv-module（包含nginx-rtmp-module），添加到nginx重载配置就行，网上有很多教程。
如果不需要flv，也可以单独下载nginx-rtmp-module，添加到nginx重载配置。
2.java预览demo
1.登录海康平台海康开放平台
选择硬件产品的isup sdk下载
2.解压之后
java的这个demo直接打开，修改一下nvr信息，包括ip端口就可以直接预览。
3.实时预览
1.配置海康sdk库文件
海康文档lib文件夹下的文件就是库文件，JavaISUPDemo\lib下也有，需要注意文档是win还是linux版本的。
2.修改FPREVIEW_NEWLINK_CB代码，推流
每当NET_ECMS_StartGetRealStreamV11，开启预览时，FPREVIEW_NEWLINK_CB便会监听到预览请求。
创建管道，分别用于取流推流。异步开始调用javacv的推流方法。
PipedInputStream pis = new PipedInputStream();
PipedOutputStream pos = new PipedOutputStream();
Stream.streamMap.put("stream:"+lLinkHandle,pos);
pos.connect(pis);
CompletableFuture.runAsync(()-> {
try {
PushUtil.grabAndPushRtmp(pis,"rtmp://"+rtmphost+"/live/"+userId+"_"+ dwChannelNo);
} catch (Exception e) {
e.printStackTrace();
}
}, Executors.newFixedThreadPool(1));3.修改FPREVIEW_DATA_CB代码，取流
每当监听到视频流时，将视频流写入pos管道。注意此处不能使用redis，redis会严重影响此处代码性能，导致取流失败。每监听一次，是一个新的线程。第一块注释的代码是调试时使用，调试完之后要删掉。第二块注释代码pos也可以存到map中，使用时从map取，此处直接构造方法传进来也可以。
public class FPREVIEW_DATA_CB implements HCISUPStream.PREVIEW_DATA_CB {
private PipedOutputStream pos;
public FPREVIEW_DATA_CB(PipedOutputStream pos) {
this.pos = pos;
}
//实时流回调函数/
@Override
public void invoke(int iPreviewHandle, HCISUPStream.NET_EHOME_PREVIEW_CB_MSG pPreviewCBMsg, Pointer pUserData) throws Exception {
// if (Count == 500) {//降低打印频率
// log.info("FPREVIEW_DATA_CB callback, iPreviewHandle:{}", iPreviewHandle);
// log.info("FPREVIEW_DATA_CB callback, data length:" + pPreviewCBMsg.dwDataLen);
// Count = 0;
// }
// Count++;
long offset = 0;
ByteBuffer buffers = pPreviewCBMsg.pRecvdata.getByteBuffer(offset, pPreviewCBMsg.dwDataLen);
byte[] bytes = new byte[pPreviewCBMsg.dwDataLen];
buffers.rewind();
buffers.get(bytes);
try{
//2.将数据读入到内存空间,此处不可用redis，否则执行时间是当前10倍
// PipedOutputStream pos = Stream.streamMap.get("stream:"+iPreviewHandle);
pos.write(bytes);
} catch (Exception e) {
e.printStackTrace();
}
}
}4.javacv的推流
关于2.提到的javacv推流，linux和windows环境所需要的依赖包不同。
以下，test的是本地windows环境使用的，runtime是线上使用的，可不写，因为默认就是runtime。

推流代码原理就是，javacv抓取帧，根据帧率算出间隔时间推送到rtmp服务器。

public static void grabAndPushRtmp(PipedInputStream pis, String pushAddress) throws Exception {
Thread.sleep(500);

FFmpegLogCallback.set();
// 实例化帧抓取器对象，将文件路径传入

// FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(MP4_FILE_PATH);
// 2.从文件中取流实例化帧抓取器,此方式只能推送ps码流的MP4

long startTime = System.currentTimeMillis();
log.info("开始初始化帧抓取器");
// 下面两行设置可加可不加

// grabber.setFormat("h264");
// 初始化帧抓取器，例如数据结构（时间戳、编码器上下文、帧对象等），

// 遍历每一个流，检查其类型
for (int i=0; i< streamNum; i++) {

int audioChannels = grabber.getAudioChannels();
log.info("视频宽度[{}]，视频高度[{}]，音频通道数[{}]",
frameWidth,

// 实例化FFmpegFrameRecorder，将SRS的推送地址传入
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(pushAddress,
frameWidth,
frameHeight,
audioChannels);
// 设置编码格式
recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
// 设置封装格式
recorder.setFormat("flv");
// 一秒内的帧数
recorder.setFrameRate(frameRate);
// 两个关键帧之间的帧数
recorder.setGopSize(frameRate);
// 设置音频通道数，与视频源的通道数相等
recorder.setAudioChannels(grabber.getAudioChannels());
startTime = System.currentTimeMillis();
log.info("开始初始化帧抓取器");
// 初始化帧录制器，例如数据结构（音频流、视频流指针，编码器），
// 调用av_guess_format方法，确定视频输出时的封装方式，
// 媒体上下文对象的内存分配，
// 编码器的各项参数设置
recorder.start();
log.info("帧录制初始化完成，耗时[{}]毫秒", System.currentTimeMillis()-startTime);
Frame frame;
startTime = System.currentTimeMillis();
log.info("开始推流");
long videoTS = 0;
int videoFrameNum = 0;
int audioFrameNum = 0;
int dataFrameNum = 0;
// 假设一秒钟15帧，那么两帧间隔就是(1000/15)毫秒
int interVal = 1000/frameRate;
// 发送完一帧后sleep的时间，不能完全等于(1000/frameRate)，不然会卡顿，
// 要更小一些，这里取八分之一
interVal/=8;
// 持续从视频源取帧
while (null!=(frame=grabber.grab())) {
videoTS = 1000 * (System.currentTimeMillis() - startTime);
// 时间戳
recorder.setTimestamp(videoTS);
// 有图像，就把视频帧加一
if (null!=frame.image) {
videoFrameNum++;
}
// 有声音，就把音频帧加一
if (null!=frame.samples) {
audioFrameNum++;
}
// 有数据，就把数据帧加一
if (null!=frame.data) {
dataFrameNum++;
}
// 取出的每一帧，都推送到SRS
recorder.record(frame);
// 停顿一下再推送
Thread.sleep(interVal);
}
log.info("推送完成，视频帧[{}]，音频帧[{}]，数据帧[{}]，耗时[{}]秒",
videoFrameNum,
audioFrameNum,
dataFrameNum,
(System.currentTimeMillis()-startTime)/1000);
// 关闭帧录制器
recorder.close();
// 关闭帧抓取器
grabber.stop();
grabber.close();
pis.close();
}
}
其中，Thread.sleep(500);是必要的。要保证此线程执行到后面代码时，管道中必须存在流，这样开始初始化帧抓取器才能成功。即取流线程必须先于推流线程执行。否则会报错。
