-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 (
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 n

When I used nginx and nginx-rtmp-module to build a Streaming Media Server, I encountered an embarrassing problem: when I added the nginx-rtmp-module to nginx, I first uninstalled the original nginx, and then downloaded the source code of nginx and nginx-rtmp-module to re-compile and install
Streaming Media Server. Streaming Media Servers are used in large-scale video conferences, audio and video training for enterprises; network-based on-demand video, broadcast, live broadcast, and other enterprise-level network-based media communication applications have a great future and wide application value.

1. Overview
Hadoop streaming is a programming tool provided by Hadoop that allows users to use any executable file or script file as mapper and reducer, for example:
$HADOOP _home/bin/hadoop jar $HADOOP _home/hadoop-streaming.jar \
-input/user/test/input \
-output/user/test/output \
-mapper "mymapper.sh" \
-reducer "Myreducer.sh"
-input and so on are the parameters for this command.
Hadoop Streaming is a tool for Hadoop that allows users to write MapReduce programs in other languages, and users can perform map/reduce jobs simply by providing mapper and reducer
For information, see the official Hadoop streaming document.

The purpose of using Nginx to build streaming media platform is to support the RTMP protocol, which enables users to use RTMP (RTMP://192.168.201.128/MYAPP) protocol to push streaming to the server. The other user then requests the video stream information that the user pushes. Since it is the RTMP protocol, so you can use Adobe's Flashmedialiveencoder program, but also can be more profe

Ksql is a streaming SQL engine built based on the Kafka streams API , Ksql lowers the threshold for Ingress stream processing and provides a simple, fully interactive SQL interface for processing Kafka data. Ksql is an open source, distributed, extensible, reliable , and real-time component based on the Apache 2.0 license. supports a variety of streaming operations, including aggregation (aggregate), connec
Spark streaming can receive streaming data from any arbitrary data source beyond the one's for which it has in-built support (that is, beyond flume, Kafka, files, sockets, etc .). this requires the developer to implementCyclerThat is customized for processing data from the concerned data source.

Hadoop provides mapreduce with an API that allows you to write map and reduce functions in languages other than Java: hadoop streaming uses standard streamams) as an interface for data transmission between hadoop and applications. Therefore, you can write the map and reduce functions in any language, as long as it can read data from the standard input stream (stdin) and write the output data to the standard output stream (stdout.
Apache Kafka is a distributed message publishing-subscription system. It can be said that any real-time big data processing tools lack of integration with Kafka is incomplete. This article will show you how to use Spark streaming to receive data from Kafka, here are two approaches: (1), using receivers and Kafka high-level APIs, (2), using the direct API, This is used in low-level KAFKAAPI and is not used to receivers, which is introduced in Spark 1.3
