video.js

  • 直接使用
  • 自定義控制條和樣式
  • 彈幕相關
  • plugin寫法

video.js 是開源外掛，據說甚至可以集合到gitbook上

note:
一個需要注意的點是下載下來的demo.html直接右鍵瀏覽器是打不開的，需要用iis或者nginx 或者beego這些服務端的玩意載入後，在前端瀏覽器才能看到視訊頁面。

參考文章:

直接使用

注意點：載入flash動畫後，chrome ie firefox播放介面才能統一，否則各有各的介面

自定義控制條

元件結構

Player
PosterImage
TextTrackDisplay
LoadingSpinner
BigPlayButton
ControlBar
PlayToggle
FullscreenToggle
CurrentTimeDisplay
TimeDivider
DurationDisplay
RemainingTimeDisplay
ProgressControl
SeekBar
LoadProgressBar
PlayProgressBar
SeekHandle
VolumeControl
VolumeBar
VolumeLevel
VolumeHandle
MuteToggle

使用：以新增按鈕為例子

var player = videojs("example_video", {
"controls": true,
"autoplay": false,
"preload": "auto",
"loop": false,
controlBar: {
captionsButton: false,
chaptersButton: false,
playbackRateMenuButton: true,
LiveDisplay: true,
subtitlesButton: false,
remainingTimeDisplay: true,

progressControl: true,

volumeMenuButton: {
inline: false,
vertical: true
},//豎著的音量條
fullscreenToggle: true
}

}, function () {
/*次處用於自定義控制條等*/
/*
做法1：直接append新增
*/
$(".vjs-control-bar").append('<button class="vjs-control " id="danmu_send_opt"><u>按鈕1</u></button>');
/*
做法2：dom新增
*/
var controlBar,
newElement = document.createElement('div'),
newLink = document.createElement('a'),
newImage = document.createElement('img');
// Assign id and classes to div for icon
newElement.id = 'downloadButton';
newElement.className = 'downloadStyle vjs-control';
// Assign properties to elements and assign to parents
newImage.setAttribute('src','http://solutions.brightcove.com/bcls/brightcove-player/download-video/file-download.png');
newLink.setAttribute('href','http://www.baidu.com');
newLink.appendChild(newImage);
newElement.appendChild(newLink);
// Get control bar and insert before elements
// Remember that getElementsByClassName() returns an array
controlBar = document.getElementsByClassName('vjs-control-bar')[0];
// Change the class name here to move the icon in the controlBar
insertBeforeNode = document.getElementsByClassName('vjs-fullscreen-control')[0];
// Insert the icon div in proper location
controlBar.insertBefore(newElement,insertBeforeNode);
//controlBar.appendChild(newElement);

/*
做法3：簡化2的寫法
*/
var newbtn = document.createElement('btn');
newbtn.innerHTML = '<button class="vjs-control" id="downloadButton"></button>';
var controlBar = document.getElementsByClassName('vjs-control-bar')[0];
insertBeforeNode = document.getElementsByClassName('vjs-fullscreen-control')[0];
controlBar.insertBefore(newbtn,insertBeforeNode);
});

自定義控制條完整例子：
新增滑條音訊控制和彈幕樣式開關

自定義樣式：

video.js 採用flex佈局，所以float這種不起作用

如果想要使用float,需要修改預設的video.js.css

並且後面的按鈕都要進行樣式調整

.vjs-has-started .vjs-control-bar {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
/*原為flex*/
display: block;
visibility: visible;
opacity: 1;
-webkit-transition: visibility 0.1s, opacity 0.1s;
-moz-transition: visibility 0.1s, opacity 0.1s;
-o-transition: visibility 0.1s, opacity 0.1s;
transition: visibility 0.1s, opacity 0.1s;
}

……省略無關部分
.video-js .vjs-play-control {
/*增加float*/
float:left;
cursor: pointer;
-webkit-box-flex: none;
-moz-box-flex: none;
-webkit-flex: none;
-ms-flex: none;
flex: none;
}

.video-js .vjs-fullscreen-control {
cursor: pointer;
-webkit-box-flex: none;
-moz-box-flex: none;
-webkit-flex: none;
-ms-flex: none;
flex: none;
/*增加float*/
float: right;
}

彈幕

使用開源jquery.danmu.js

jquery彈幕外掛使用
