Spark StreamingSpark streaming uses the spark API for streaming calculations, which means that streaming and batching are done on spark. So you can reuse batch code, build powerful interactive applications using Spark streaming, and not just analyze data. Spark Streaming Ex

Three kinds of frameworks for streaming big data processing: Storm,spark and SamzaMany distributed computing systems can handle big data streams in real-time or near real-time. This article provides a brief introduction to the three Apache frameworks, such as Storm, Spark, and Samza, and then tries to quickly and highly outline their similarities and differences.Many distributed computing systems can handle big data streams in real-time or near real-t

The current mainstream streaming servers are Microsoft's Windows Media Server, RealNetworks Helixserver and Apple's Darwin streaming server. Microsoft Windows Media Server can only be used under Windows2000 Server and Windows 2003 server, not in the list of considerations. RealNetworks's Helixserver is a cross-platform software that is also powerful, but not freeware.Darwin

Preface:　　　　Recently in the research Spark also has Kafka, wants to pass the data which the Kafka end obtains, uses the spark streaming to carry on some computation, but constructs the entire environment is really not easy, therefore hereby writes down this process, shares to everybody, hoped that everybody may take a little detour, can help everybody!Environment Preparation:operating system: ubuntu14.04 LTSHadoop 2.7.1 Pseudo-distributed construction

MPMoviePlayerController Brief introductionMPMoviePlayerController both support local audio and video playback also support network streaming media playback, the function has been very perfect, streaming media projects commonly used requirements can be met, such as play, pause, fast forward, back, listen to the playback status of the player, and other functions, At the same time MPMoviePlayerController p

Overview Flume: A distributed, reliable, and usable service for efficiently collecting, aggregating, and moving large-scale log data We build a flume + Spark streaming platform to get data from flume and process it. There are two ways to do this: Use the push-based method of Flume-style, or use a custom sink to implement the Pull-based method. Approach 1:flume-style push-based Approach Flume is designed to push informati

This article continues the previous article, documenting some examples of flash-based streaming media processing. This article records some of the web player based on flash technology. The biggest advantage of Flash-based web player compared to other Web players is "plug-in Installation", which can greatly improve the quality of user experience. Earlier online video (especially live streaming) used ActiveX

Introduction to the open source project for streaming media1. PeercastEstablished in 2002, the earliest open source peer streaming project. Peercast the nodes by tree structure, each channel is a tree, the live source is the root node, the parent node only provides data to the child nodes. The farther away the node is from the root node, the greater the transmission delay, so the depth of the tree should be

2008.7.17 The program cannot connect to the server through cmnet on the mobile phone, but the mobile phone can connect to the server (such as HTTP and RealPlayer ). You can also connect to the Internet IP address of the server in the simulator. You have to study rtspclient and socket in the morning. 2008.7.18 Test with rsocket example. If the problem is the same, the connection cmnet prompts "conn. Failed-46". The permission is insufficient. Originally, the socket required the networkservices ca

After installing Darwin streaming Server, you can use VLC to play streaming media files through the RTSP protocol. But now I have a need to send a DSS (assumed to be a machine) on the media file to another DSS (assuming B machine) on the client VLC by accessing the B machine to play the media files of a machine, that is, using B machine as a forwarding server. I found a lot of articles on the internet about
