Design BackgroundSpark Thriftserver currently has 10 instances on the line, the past through the monitoring port survival is not accurate, when the failure process does not quit a lot of situations, and manually to view the log and restart processing services This process is very inefficient, so design and use spark Streaming to the real-time acquisition of the spark Thriftserver log, through the log to determine whether the service stopped service, s

-write log before the database is actually changed. This guarantees that the timestamp of the pre-write log will never lag behind the database, even if the server is suddenly crashing at the time of the write, and the data can be recovered from the pre-write log after the restart because the pre-write log retains the newer version than the database record. The asynchronous replication solution for PostgreSQL is the use of a pre-written log to transfer the pre-written log from the primary server

Use free UMS to set up flash streaming servicesWith the popularity of the Adobe Flash Player (according to Adobe's official data, Flash Player installed up to 99%), more and more network video began to use Flash Player as the playback front end, so More and more businesses are starting to retire from other types of streaming media servers using a streaming media

There are two basic requirements for achieving a stable viewing experience in web-based high-definition digital video transmission. First, the video provider needs to support a higher video transmission bit rate on the network. Second, the client computer needs to support continuous processing capabilities to decode the video at full resolution. The reality is that over time, the network bandwidth of home networking computers fluctuates significantly, and in some parts of the world, high bandwi

In general, a streaming media system consists of several components: a transfer/transcoding tool (Encoders) for compressing a shift, a server (servers), managing and delivering a large number of multimedia content, encoders (scripters), integrating multimedia, and presenting in an interactive manner The player (players), which presents streaming content on the client's PC, and a number of different multimed

The promotion of multimedia applications in Linux is not measurable.RTSP/RTP streaming support for mplayerThe Open Source "mplayer" Media Player can now receive and play standards-compLiant RTP audio/video streams, using the "live555 Streaming Media" source codeLi

Recently, due to a company's Android project, we need to upload a video to the server to enable upload, download, and play. This involves playing streaming media videos on the mobile terminal of the video. Therefore, I am working with a Darwin Streaming Media Server, this article also references: Baidu Library: Baidu?

By default, when performing calculations, he had to complete the fault tolerance of two machines before he began to actually perform calculations. Receiver receives data if it crashes, this time there will be no data loss, when the def

The live555 streaming media server is one of the related projects that I've done before in retrospect, so let's take a look at the live555 Open source framework's compilation method under Windows today.LIVE555 is a set of open-source C + + libraries that use open standard protocols (RTP/RTCP, RTSP, SIP) to process multimedia streaming data using the LGPL protocol. These libraries can be compiled into UNIX (

Many distributed computing systems can handle big data streams in real-time or near real-time. This article will briefly introduce the three Apache frameworks, and then try to quickly and highly outline their similarities and differences.Apache StormIn storm, we first design a graph structure for real-time computing, which we call topology (topology). This topology will be presented to the cluster, which distributes the code by the master node in the cluster and assigns the task to the worker no

In the following example, I will use red5 as the Streaming Media Server and use the xml configuration file reading technology, mongodobject parameter passing and event passing mechanisms (note: the event itself can store and PASS Parameters ). Read the configuration file, including the streaming media service connection address and the name of the initialized video. Code highlighting produced by Actipro

There have also been recent studies using spark streaming for streaming. This article is a simple example of how to do spark streaming programming with the flow-based count of word counts.1. Dependent jar PackagesRefer to the article "Using Eclipse and idea to build the Scala+spark development environment," which specifies a dependency library Spark-streaming_2.1

-lapse interactive voice-on-demand on the internet is a commonplace thing, but it is working on the Internet, in the more ocean over the sea of the congested links on the road, the sound of delay and loss is often difficult to accept. Even in the Continental region, the quality of the sound is greatly reduced due to the congestion at the peak.　　Summed up, the current multimedia network application to focus on the problem is: ① increase network bandwidth, ② reduce delay (delay), ③ reduce jitter (
