How uniapp implements live broadcast
Uniapp’s method of implementing live broadcast: first push the stream, the code is [ ]; Then use the video tag to pull the stream.
The operating environment of this tutorial: windows7 system, uni-app2.5.1 version, Dell G3 computer.
uniapp's method of implementing live broadcast:
1. Push streaming
<template> <view class="content"> <template> <view> <live-pusher id="livePusher" ref="livePusher" class="livePusher" url="" **这里需要请求后端接口,拿到推流地址** mode="SD" :muted="true" :enable-camera="true" :auto-focus="true" :beauty="1" whiteness="2" aspect="9:16" @statechange="statechange" @netstatus="netstatus" @error="error" ></live-pusher> <button class="btn" @click="start">开始推流</button> <button class="btn" @click="pause">暂停推流</button> <button class="btn" @click="resume">resume</button> <button class="btn" @click="stop">停止推流</button> <button class="btn" @click="snapshot">快照</button> <button class="btn" @click="startPreview">开启摄像头预览</button> <button class="btn" @click="stopPreview">关闭摄像头预览</button> <button class="btn" @click="switchCamera">切换摄像头</button> <button class="btn" @click="bofang">去播放</button> </view> </template> </view> </template> <script> export default { data() { return { context:[] }; }, onReady() { // 注意:需要在onReady中 或 onLoad 延时 this.context = uni.createLivePusherContext('livePusher', this); }, methods: { statechange(e) { console.log('statechange:' + JSON.stringify(e)); }, netstatus(e) { console.log('netstatus:' + JSON.stringify(e)); }, error(e) { console.log('error:' + JSON.stringify(e)); }, start(){ this.context.start({ success: a => { console.log('livePusher.start:' + JSON.stringify(a)); }, error:err=>{ console.log(err) } }); }, close() { this.context.close({ success: a => { console.log('livePusher.close:' + JSON.stringify(a)); } }); }, snapshot() { this.context.snapshot({ success: e => { console.log(JSON.stringify(e)); } }); }, resume() { this.context.resume({ success: a => { console.log('livePusher.resume:' + JSON.stringify(a)); } }); }, pause() { this.context.pause({ success: a => { console.log('livePusher.pause:' + JSON.stringify(a)); } }); }, stop() { this.context.stop({ success: a => { console.log(JSON.stringify(a)); } }); }, switchCamera() { this.context.switchCamera({ success: a => { console.log('livePusher.switchCamera:' + JSON.stringify(a)); } }); }, startPreview() { this.context.startPreview({ success: a => { console.log('livePusher.startPreview:' + JSON.stringify(a)); } }); }, stopPreview() { this.context.stopPreview({ success: a => { console.log('livePusher.stopPreview:' + JSON.stringify(a)); } }); }, bofang(){ this.$u.route({ url: 'pages/index/index' }) } } }; </script> <style> .content { display: flex; flex-direction: column; align-items: center; justify-content: center; } .logo { height: 200rpx; width: 200rpx; margin-top: 200rpx; margin-left: auto; margin-right: auto; margin-bottom: 50rpx; } .text-area { display: flex; justify-content: center; } .title { font-size: 36rpx; color: #8f8f94; } </style> **
2. Pull streaming
Here is the app streaming, using the video tag, the code is as follows
<template> <view> <video src="" style="width: 100vw;height: 400rpx;" :autoplay="true" controls></video> </view> </template> <script> export default {} </script>
src
is the streaming address obtained from the request interface

Steps to launch UniApp project preview in WebStorm: Install UniApp Development Tools plugin Connect to device settings WebSocket launch preview

Generally speaking, uni-app is better when complex native functions are needed; MUI is better when simple or highly customized interfaces are needed. In addition, uni-app has: 1. Vue.js/JavaScript support; 2. Rich native components/API; 3. Good ecosystem. The disadvantages are: 1. Performance issues; 2. Difficulty in customizing the interface. MUI has: 1. Material Design support; 2. High flexibility; 3. Extensive component/theme library. The disadvantages are: 1. CSS dependency; 2. Does not provide native components; 3. Small ecosystem.

uniapp development requires the following foundations: front-end technology (HTML, CSS, JavaScript) mobile development knowledge (iOS and Android platforms) Node.js other foundations (version control tools, IDE, mobile development simulator or real machine debugging experience)

UniApp has many conveniences as a cross-platform development framework, but its shortcomings are also obvious: performance is limited by the hybrid development mode, resulting in poor opening speed, page rendering, and interactive response. The ecosystem is imperfect and there are few components and libraries in specific fields, which limits creativity and the realization of complex functions. Compatibility issues on different platforms are prone to style differences and inconsistent API support. The security mechanism of WebView is different from native applications, which may reduce application security. Application releases and updates that support multiple platforms at the same time require multiple compilations and packages, increasing development and maintenance costs.

When choosing between UniApp and native development, you should consider development cost, performance, user experience, and flexibility. The advantages of UniApp are cross-platform development, rapid iteration, easy learning and built-in plug-ins, while native development is superior in performance, stability, native experience and scalability. Weigh the pros and cons based on specific project needs. UniApp is suitable for beginners, and native development is suitable for complex applications that pursue high performance and seamless experience.

UniApp is based on Vue.js, and Flutter is based on Dart. Both support cross-platform development. UniApp provides rich components and easy development, but its performance is limited by WebView; Flutter uses a native rendering engine, which has excellent performance but is more difficult to develop. UniApp has an active Chinese community, and Flutter has a large and global community. UniApp is suitable for scenarios with rapid development and low performance requirements; Flutter is suitable for complex applications with high customization and high performance.

Recommended component library for uniapp to develop small programs: uni-ui: Officially produced by uni, it provides basic and business components. vant-weapp: Produced by Bytedance, with a simple and beautiful UI design. taro-ui: produced by JD.com and developed based on the Taro framework. fish-design: Produced by Baidu, using Material Design design style. naive-ui: Produced by Youzan, modern UI design, lightweight and easy to customize.
