<span id="Label3"></p>Live stream Source development tells you what you need to know about developing live apps<br>2018 is where video Live is a big fire to unpredictable future market Value. Now there are different businesses in the field of video broadcasting that offer a variety of business solutions, including soft hardware, cameras, encoders, streaming media servers, and More. So today I would like to give you the analysis in this article is how to develop live streaming app to understand the principles of what is, how to choose software development vendors, including after-sales service, to create a set of video broadcast Program. Live industry because of strong technical support, go more and more stable, to introduce some of the video broadcast system development needs to pay attention to the key issues! For the development of video broadcasting system, the first is the system development language, we look at the common development language! Video live system is usually composed of WEB system, REDIS service, MYSQL service, video service, Chat Service Node. js, background Management system and timing monitoring, mobile phone end Android language adoption: java, IOS Apple adoption: objective-c? native development, Background management with PHP language development, all services provide Scale-out.<br>The 1th is: to stay in the live source development of video, Audio capture video, Audio Coding framework?<br>Avfoundation:avfoundation is a framework for playing and creating real-time audio-visual media data, while providing an Objective-c interface to manipulate these audiovisual data, such as editing, rotating, recoding<br>2nd: video, Audio hardware equipment? live streaming source development<br>CCD image sensor: used in the process of image acquisition and processing, the image is converted into electrical signals.<br>Pickup: sound sensor: used in the process of sound acquisition and processing, the sound is converted into electrical signals.<br>Audio sampling data: typically PCM format<br>Video sampling data:: generally is yuv, or RGB format, the acquisition of the original audio and video volume is very large, the development of live direct source code should be compressed technology to improve transmission efficiency<br>3rd: Video Processing (beauty, watermark) The development of live source<br>Video processing principle: Because the video is finally through the gpu, one frame to render to the screen, so we can use OpenGL ES, video frames for various processing, so that the video a variety of different effects, like a faucet out of the water, after several sections of the pipeline, and then flow to different targets<br>Now all kinds of beauty and video add effects app are using Gpuimage<br>This framework is implemented by The.<br>4th: the video encoding and decoding video coding framework<br>These are the steps of the framework on how to implement<p><p></p></p> <ol> <ol> <li>Long live source development web system provides page, interface Logic.</li> <li>Long live source Development Redis service provides data caching and dynamic Data Storage.<br>3.
