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,
file1.ts
#EXTINF:14.600000,
file2.ts
#EXT-X-ENDLIST
web前端查看m3u8视频

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,
