介绍

DPlayer是一个视频播放器,封装很多实用的api

安装

使用 npm:

npm install dplayer --save

使用 Yarn:

yarn add dplayer

快速开始

我们先尝试初始化一个最简单的 DPlayer

加载播放器文件:

<div id="dplayer"></div>
<script src="DPlayer.min.js"></script>

或者使用模块管理器:

import DPlayer from 'dplayer';

const dp = new DPlayer(options);

在 js 里初始化:

const dp = new DPlayer({
    container: document.getElementById('dplayer'),
    video: {
        url: 'demo.mp4',
    },
});

一个最简单的 DPlayer 就初始化好了,它只有最基本的视频播放功能

                client.add(torrentId, (torrent) => {
                    const file = torrent.files.find((file) => file.name.endsWith('.mp4'));
                    file.renderTo(

                });
            },
        },
    },
});

配合其他 MSE 库使用

DPlayer 可以通过 customType 参数与任何 MSE 库一起使用,例如支持P2P插件:

<div id="dplayer"></div>
<script src="https://cdn.jsdelivr.net/npm/cdnbye@latest"></script>
<script src="DPlayer.min.js"></script>
var type = 'normal';
if(Hls.isSupported() && Hls.WEBRTC_SUPPORT) {
    type = 'customHls';
}
const dp = new DPlayer({
    container: document.getElementById('dplayer'),
    video: {
        url: 'demo.m3u8',
        type: type,
        customType: {
            'customHls': function (video, player) {
                const hls = new Hls({
                    debug: false,
                    // Other hlsjsConfig options provided by hls.js 
                    p2pConfig: {
                        live: false,        // 如果是直播设为true// Other p2pConfig options provided by CDNBye http://www.cdnbye.com/cn/
                    }
                });
                hls.loadSource(video.src);
                hls.attachMedia(video);
            }
        }
    },
});

直播

你可以把 DPlayer 用在直播当中,但如果你想要直播弹幕,你需要自己准备一个 WebSocket 后端。

Load demo

初始化播放器:

const dp = new DPlayer({
    container: document.getElementById('dplayer'),
    live: true,
    danmaku: true,
    apiBackend: {
        read: function (endpoint, callback) {
            console.log('Pretend to connect WebSocket');
            callback();
        },
        send: function (endpoint, danmakuData, callback) {
            console.log('Pretend to send danmaku via WebSocket', danmakuData);
            callback();
        },
    },
    video: {
        url: 'demo.m3u8',
        type: 'hls',
    },
});

通过 WebSocket 获取到弹幕之后,通过 dp.danmaku.draw 绘制弹幕:

const danmaku = {
    text: 'Get a danmaku via WebSocket',
    color: '#fff',
    type: 'right',
};
dp.danmaku.draw(danmaku);
