First step: first introduce the relevant technology usedNote: The Jwplayer plug-in used in the project does not support the RTSP protocol, so use the following techniques to turn the art FFmpeg is an open-source computer program that can be used to record, convert digital audio, video, and turn it into a stream. Here I only use its video format conversion function, the RTSP protocol to the stream into rtmp RTSP protocol ( live stream Transfer Protocol ): The company uses Hoi Ho

V4L (Video4linux is the basis of some video systems, video software, audio software, often in the need to capture images of the occasion, such as video surveillance, webcam, videophone, oftenUsing the system interface that is often used in Linux embedded development in embedded Linux. It is the programming interface that the Linux kernel provides to the user space, all kinds of video and audio equipment openAfter the corresponding driver, you can cont

The number of surveillance cameras that need to be recorded, such as 6 cameras needed to save video, is 6. Calculation method: Single-day Video size = main stream (M) ÷8x3600 (sec) x24 (hour) x channel number ÷1024 Video days = hard disk Capacity (G) x1024x coefficient x8÷3600 (seconds) ÷24 (time) main stream (M) Number of channels such as: 1 1080P camera, 4M main stream of the day video size: 4÷8X3600X24X1=43200M≈42GB Note: The following provi

, popularity has surpassed the business Reds Li Ka-shing thousands of points, the top Shi Jing. The chart below is the top ten figures for 31st: A big reason to pay attention to Jin is that he is the finance minister, just like all the people concerned about the drug chief Zheng. These high-level people are far away from the people, the people are naturally curious about them, their movements can arouse people's attention, coupled with a number of Hong Kong media reported that Jin was in the

photographer's color game more vivid and intuitive. Software skin: In the Software graphics interface design application HSL color, and set a simple transformation rules, you can achieve friendly and easy to use the skin function. Video surveillance/motion capture: HSL the brightness l component of color model is independent of color information, easy to identify and analyze, H and S component is similar to human visual perception, so it is very su

This article mainly gives you a summary of 2 ways to implement the iOS touch-screen event, simple and practical, the need for small partners can refer to. The code is as follows: Inside a function (initialization, etc.), add the scope to identify the touch event Infoview=[[uiview Alloc] Initwithframe:cgrectmake (20, 100,220, 280)];//range, out of this range will not detect the touch of Infoview.backgroundcolor=[uicolor Bluecolor]; infoview.alpha=0.6; [Self.view Addsubview:infoview]; /****

wait until the user tells you that the site can't be opened. For the sake of convenience we use the surveillance treasure and Aliyun monitoring (main Aliyun monitor has free SMS). You should locate the cause of this problem every time you appear to be unable to open the site. If the frequency increases, you should consider coping strategies. Loadavg a good response to the system load, you can determine whether the hardware bottlenecks. In the event

This article describes the use of Node-exporter, Prometheus, Grafana to monitor the cluster in a k8s cluster.Its implementation principle is somewhat similar to elk, EFK combination. The Node-exporter component collects the metrics monitoring data on the node and pushes the data to Prometheus, Prometheus is responsible for storing the data, and grafana the data to the user in a graphical form on the Web page. Before you begin, it is necessary to understand what the next Prometheus is. Prometheu

%, and CPU consumption should be up and down, the server with this problem, the CPU will suddenly be at 100% level, and will not drop. Viewing Task Manager, you can find that DLLHOST.EXE consumes all of the CPU idle time, in which case the administrator has to restart the IIS service, and strangely, after restarting the IIS service, everything is fine, but it may be a while before the problem comes back. Direct reason: One or more Access databases are corrupted during multiple reads and writes

modifications, you can still access the discuz! on a machine with Norton Internet security installed and other websites. ************************************************************ Q: Someone in the unit is using BT to download a lot of things. I used to seal off the outer 6969 ports on the firewall as if it worked, but lately it doesn't seem to have any effect. Do you have any good suggestions? A: Then use a firewall to seal 6999-9999 ports, but they will also open other, with

install the drive. Take a few days to see if this problem does not occur, and then install other software, but it is best to install a software, first in a few days. There are problems and then install! Features: Server normal CPU consumption should be below 75%, and CPU consumption should be up and down, the server with this problem, the CPU will suddenly be at 100% level, and will not drop. Looking at task Manager, you can see that DLLHOST.EXE consumes all of the CPU idle time, In this cas

under actual load.Opentracing and Zipkin are sufficient to handle this task in most modern programming languages and do not add additional burdens after encapsulating the code. Of course, all the data collected should be stored in the appropriate place and used as a component.The development standards and service templates described above can address the complexities of encapsulating code and forwarding "Trace IDs" through services, message queues, databases, and so on. The latter also takes in
