Author: kgezhi Wang 2009-12-16 reprinted please indicate the source, thank you. This article describes how to quickly build a media stream server that complies with the 3GPP standard and use a built-in player (such as RealPlayer) on your mobile phone for Vod. This article introduces mainstream Real Helix and Apple Darwin respectively. 1. Helix Streaming Server First, we will introduce the helix streaming

1 basic information editing Vitamio is an all-in-one multimedia development framework on Android and IOS platforms that supports both hardware decoding and GPU rendering.

Streaming media is a technology that plays multimedia online on the network. Because of its downloading and playing features, it shortens the user's initial waiting delay, but its data also needs to be streamed, with high real-time requirements, therefore, it is more complicated than local playback. The client is a basic component of the streaming media system. It is generally a player with network communic

color of paint, The RGB mode is often used on the monitor, which is different from the pal or NTSC video standard. Conversion between YUV and yiq The conversion formula between YUV, yiq, and RGB is as follows: Y = 0.299r + 0.587G + 0.114b U = B ━ y V = r y I = 0.877 (R-Y) cos33 platinum 0.492 (B-Y) sin33 Q = 0.877 (R-Y) sin33 + 0.492 (B-Y) cos33 RGB is composed of three primary colors: R, G, and B. Similarly, YUV is composed of three elements: Y, U, and V. In pal The conversion formula used for

FFMPEG and ffserver can be used together to implement real-time Streaming Media Services. I. Understanding There are four main things in it, and the relationship between them is almost clear. 1. FFMPEG 2. ffserver 3. ffserver. conf 4. feed1.ffm 1. FFmpeg is responsible for the transcode of media files. It converts the source media files on your server into the streaming media files to be sent. 2. ffs

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

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
