How to implement video recording and editing functions in uniapp
Uniapp (Universal App) is a development framework based on Vue.js, which can use Vue syntax and cross-platform development capabilities at the same time. The framework can compile code into different pages on multiple platforms. This article will introduce how to implement video recording and editing functions in Uniapp and provide specific code examples.
1. Implementation of video recording function
To realize the video recording function, we must first introduce the uni-mp-video plug-in. This plug-in is a video playback and recording component on the Uniapp development platform, providing rich functions.
- Find the package.json file in the root directory of the project and add the following code in the dependencies section:
"dependencies": {
... "uni-mp-video": "^1.0.0"
}
- Run the npm install command to install the plugin.
- Use this plug-in in the vue file of the page that needs to use the video recording function:
<mp-video :src="videoSrc" :autoplay="true" controls></mp-video> <button @tap="startRecord">开始录制</button> <button @tap="endRecord">结束录制</button>
< ;/view>
<script><br> import mpVideo from 'uni-mp-video'<br> export default {</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>data() { return { videoSrc: '' } }, components: { mpVideo }, methods: { async startRecord() { try { const { tempVideoPath } = await uni.getRecorderManager().start({ duration: 60, // 录制时长，单位为秒 format: 'mp4' // 录制格式 }) this.videoSrc = tempVideoPath } catch (err) { console.log(err) } }, endRecord() { uni.getRecorderManager().stop() } }</pre><div class="contentsignin">Copy after login</div></div><p>}<br></script>
In the above code snippet, we introduced the plug-in and referenced the component on the page. In methods, we define the startRecord() method to start the recording function, and obtain the recorded video path after the recording is completed, and bind it to the videoSrc attribute so that it can be displayed on the page. The endRecord() method is used to end the recording function.
2. Implementation of video editing function
To realize the video editing function, you can use the uni-image-editor plug-in. This plug-in provides a rich set of image and video editing functions based on uniapp, including cropping, zooming, rotating, filters and other functions.
- Find the package.json file in the root directory of the project and add the following code in the dependencies section:
"dependencies": {
... "uni-image-editor": "^1.0.0"
}
- Run the npm install command to install the plugin.
- Use this plug-in in the vue file of the page that needs to use the video editing function:
<mp-video :src="videoSrc" :autoplay="true" controls></mp-video> <button @tap="editVideo">剪辑视频</button>
< ;/view>

Which one is better, uniapp or mui?
Apr 06, 2024 am 05:18 AM
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.
What are the disadvantages of uniapp
Apr 06, 2024 am 04:06 AM
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.
What is the difference between uniapp and flutter
Apr 06, 2024 am 04:30 AM
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.
What basics are needed to learn uniapp?
Apr 06, 2024 am 04:45 AM
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)
Which is better, uniapp or native development?
Apr 06, 2024 am 05:06 AM
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.
