vue中使用video标签播放MP4，m3u8格式视频
步骤
安装openssl
参考：Security OAuth2 授权 & JWT 中安装openssl部分、安装OpenSSL
下载 openssl安装包，一般下载列表第1个EXE即可(不带light的是完整功能的安装包，我们用不到)，下载完成后双击安装一直点下一步就行了。
配置环境变量，老生常谈，openssl的默认安装路径为C:\Program Files\OpenSSL-Win64\bin，这里有windows配置环境变量的通用教程，最后我们验证下是否配置成功openssl -v 或者 openssl version。
centos7安装openssl：sudo yum install pcre-devel openssl openssl-devel -y
生成一个enc.key文件
生成一个enc.key文件，license与windows指令相同
生成加密串
生成加密串（b6dc7333568a0deef8e6b331b9725264），记下来
创建enc.keyinfo文件
新建一个文件 enc.keyinfo 内容格式如下：
Key URI # enc.key的路径，使用http形式
Path to key file # enc.key文件
IV # 上面生成的iv
示例
http://localhost/video/enc.key
enc.key
b6dc7333568a0deef8e6b331b9725264
视频切分
视频切分，传一个test.mp4到enc.key路径下，通过黑窗口执行下面的指令
ffmpeg -y -i test.mp4 -hls_time 12 -hls_key_info_file enc.keyinfo -hls_playlist_type vod -hls_segment_filename "file%d.ts" playlist.m3u8
- 解释
ffmpeg -y \ -i test.mp4 \ -hls_time 12 \ # 将test.mp4分割成每个小段多少秒 -hls_key_info_file enc.keyinfo \ -hls_playlist_type vod \ # vod 是点播，表示PlayList不会变 -hls_segment_filename "file%d.ts" \ # 每个小段的文件名 playlist.m3u8 # 生成的m3u8文件
m3u8文件
这个URI路径可以修改，只要能返回enc.key的数据就行了
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:50
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-KEY:METHOD=AES-128,URI="http://localhost/video/enc.key",IV=0xb6dc7333568a0deef8e6b331b9725264
#EXTINF:50.000000,
file0.ts
#EXTINF:50.000000,

#EXTINF:14.600000,

当未提供enc.key的文件时，报错
直接修改m3u8的URI也是没问题的，只要后台改了就行

dplayer切换播放视频(弹幕)
-
可以切换视频，可以发送弹幕（发送完弹幕后，可以在本地显示，可以调用dp.danmaku.send(danmaku, callback: function): 提交一个新弹幕，后面可以使用websoket将代码发到其它观看此视频的用户）
-
必须引入DPlayer.min.css，否则弹幕无法正常显示
-
有个问题：按照官网设置的danmaku的token，但是在请求弹幕接口的时候没有携带这个请求头，不知道该问题的原因（哦，原来是发送弹幕的时候，会携带这个danmaku.token参数到Request Payload中，我还以为请求弹幕的时候，也得带呢）
-
弹幕的格式：每条弹幕都是1个数组，数组中按顺序依次是：time-时间，type-类型，color-颜色，author-发送者，text-内容
-
弹幕返回的示例可以参考，
https://s-sh-17-dplayercdn.oss.dogecdn.com/1678963.json：{ "code": 0, "data": [ [ 230.523, 0, 16777215, "618c713c", "键盘妹子挺好看？" ], [ 25.837, 0, 16777215, "6b2884ac", "Goose house炒鸡棒！！！ 银之匙种草他们组合" ], [ 235.243, 1, 16707842, "929815d3", "刚才说比其他翻唱都好听的你是认真的么，这。就是原唱" ], [ 86.841, 0, 16777215, "6f30afd1", "喜欢短发的" ] ] }
