2.步骤
1.搭建rtmp+flv服务器
2.java预览demo
3.实时预览
1.配置海康sdk库文件
2.修改FPREVIEW_NEWLINK_CB代码,推流
3.修改FPREVIEW_DATA_CB代码,取流
4.javacv的推流
3.部分代码
1.启动项目初始化cms,stream的代码
2.cms代码
3.stream代码
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。

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);

audioFrameNum,

// 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。文章来源:https://www.toymoban.com/news/detail-573232.html
