Javascript 使用MediaElement.js从任意位置播放HTML5视频

我需要能够从任意位置播放HTML5视频mp4格式

<script src="{{ STATIC_URL }}mediaelementjs/jquery.js"></script>
<script src="{{ STATIC_URL }}mediaelementjs/mediaelement-and-player.min.js"></script>
<link rel="stylesheet" href="{{ STATIC_URL }}mediaelementjs/mediaelementplayer.min.css" />

<script>
    $(document).ready(function(){$('video, audio').mediaelementplayer({
        // if the <video width> is not specified, this is the default
        defaultVideoWidth: 480,
        // if the <video height> is not specified, this is the default
        defaultVideoHeight: 270,
        // if set, overrides <video width>
        videoWidth: -1,
        // if set, overrides <video height>
        videoHeight: -1,
        // width of audio player
        audioWidth: 400,
        // height of audio player
        audioHeight: 30,
        // initial volume when the player starts
        startVolume: 0.8,
        // useful for <audio> player loops
        loop: false,
        // enables Flash and Silverlight to resize to content size
        enableAutosize: true,
        // the order of controls you want on the control bar (and other plugins below)
        features: ['playpause','progress','current','duration','tracks','volume','fullscreen'],
        // Hide controls when playing and mouse is not over the video
        alwaysShowControls: false,
        // force iPad's native controls
        iPadUseNativeControls: false,
        // force iPhone's native controls
        iPhoneUseNativeControls: false,
        // force Android's native controls
        AndroidUseNativeControls: false,
        // forces the hour marker (##:00:00)
        alwaysShowHours: false,
        // show framecount in timecode (##:00:00:00)
        showTimecodeFrameCount: false,
        // used when showTimecodeFrameCount is set to true
        framesPerSecond: 25,
        // turns keyboard support on and off for this instance
        enableKeyboard: true,
        // when this player starts, it will pause other players
        pauseOtherPlayers: true,
        // array of keyboard commands
        keyActions: [],
        // start with English automatically turned on
        startLanguage: 'en'
        }
    );});

<video id="demo" width="720" height="600" controls="controls" preload="auto">
    <!-- MP4 for Safari, IE9, iPhone, iPad, Android, and Windows Phone 7 -->
    <source type="video/mp4" src="{{ STATIC_URL }}/video/sample.m4v" />
    <!-- Optional: Add subtitles for each language -->
    <track label="English" srclang="en" kind="subtitles" type="text/vtt" src="{{ STATIC_URL }}video/sample.vtt" />
</video>

假设我想添加一个包含时间信息的链接，例如，从开始的10秒开始，当我单击它时，视频应该不是从开始播放，而是从10秒开始播放。在下面的发言稿中。时间00:00:10是一个可以点击的链接。谁能给我指点怎么做

第158行：这是个好词。00:00:10

…使用html5播放器播放和当前时间：

HTML:

JS:

前面的答案建议使用currentTime，它在HTML5中是一个get/set方法，但在MEJS中只是一个get方法。您应该使用MEJS的setCurrentTime来设置开始时间，这样就有了

<button class="button" id="play">play : starts at 8 seconds</button>

。。。或者您可以使用更多具有不同ID的按钮来设置更多操作，如

$("#parentContainer").on("click", ".button", function (event) {
    if (event.target.id == "play") {
        media.setCurrentTime(8);
        media.play();
    }
    if (event.target.id == "pause") {
        media.pause();
    }
});

注意：应预加载视频，以便将属性设置为有效

谢谢利马·菲尔。我试过了，但当我点击按钮时，视频没有播放。我想知道我是否遗漏了什么。我测试了这个例子，一切正常。尝试从控制台运行代码，var video=document.getElementByIddemo；video.currentTime=15；视频播放；谢谢你，肯尼迪，我成功了！我想知道你是否能再帮我一件事。我试图在视频中显示字幕，但不知道在哪里以及如何设置合适的语言声明条款——惊人的语言：“恩”；你能给我一些指点吗？没关系。我想出来了。只需在success子句之前设置“en”。再次感谢！

<button class="button" id="play">play : starts at 8 seconds</button>

var media; // we need this global variable
jQuery(document).ready(function ($) {
    $("video").mediaelementplayer({
        success: function (mediaElement, domObject) {
            media = mediaElement; // make it available for other functions
        }
    });
    $(".button").on("click", function () {
        media.setCurrentTime(8); // set starting time
        media.play(); 
    });
}); // ready

$("#parentContainer").on("click", ".button", function (event) {
    if (event.target.id == "play") {
        media.setCurrentTime(8);
        media.play();
    }
    if (event.target.id == "pause") {
        media.pause();
    }
});
