如何在录制时监听timeupdate事件？

Question

是否可以在录制时监听timeupdate事件并获取当前时间？我使用videojs和videojs-record插件来录制视频和音频。我尝试在videojs的播放器对象上监听时间更新，但没有结果-它没有被触发

看一看https://collab-project.github.io/videojs-record/#/recorded-data?id=timestamps

基本上使用timeSlice选项启用事件：

record: {
    audio: false,
    video: true,
    maxLength: 5,
    debug: true,
    // fire the timestamp event every 2 seconds
    timeSlice: 2000
}

并监听时间戳事件。例如：

// monitor stream data during recording
player.on('timestamp', function() {
    // timestamps
    console.log('current timestamp: ', player.currentTimestamp);
    console.log('all timestamps: ', player.allTimestamps);

    // stream data
    console.log('array of blobs: ', player.recordedData);
    // or construct a single blob:
    // var blob = new Blob(blobs, {
    //     type: 'video/webm'
    // });
});
