One, Vue
We still use the Vue.js file from the previous article
Here Vue implements the camera function
2. Create a directory
3. Realization
1. index.html
Code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="vue.js"></script>
</head>
<body>
<div id="vueapp">
<div>
<button @click="btnRecordClicked" :disabled="recording">录制</button>
<button @click="btnPauseClicked" :disabled="paused||!recording">暂停</button>
<button @click="btnResumeClicked" :disabled="!paused||!recording">继续</button>
<button @click="btnStopClicked" :disabled="!recording">停止</button>
<button :disabled="!currentWebmData" @click="btnPlayClicked">播放</button>
</div>
<video controls ref="player"></video>
</div>
<script src="app.js"></script>
</body>
</html>
2. app.js
code
new Vue({ el:"#vueapp", data:{ currentWebmData:0, recording:false, paused:false }, mounted() { this._initApp(); }, methods:{ async _initApp(){ // this._stream=await navigator.mediaDevices.getUserMedia({audio:true,video:false}); this._stream=await navigator.mediaDevices.getDisplayMedia(); this._recorder=new MediaRecorder(this._stream,{mimeType:"video/webm;codecs=h264"}); this._recorder.ondataavailable=this.recorder_dataAvailableHandler.bind(this); },
recorder_dataAvailableHandler(e){ console.log(e); this.currentWebmData=e.data; }, btnRecordClicked(){ this.recording=true; this.paused=false; this._recorder.start(); }, btnPauseClicked(){ this.paused=true; this._recorder.pause(); }, btnResumeClicked(){ this.paused=false; this._recorder.resume(); }, btnStopClicked(){ this.recording=false; this._recorder.stop();
},
btnPlayClicked(){ this.$refs.player.src=URL.createObjectURL(this.currentWebmData);} } });
Fourth, the effect
1. Select the range to record
2. You can click to start recording
