Java实现视频加密及播放

使用ffmpeg视频切片并加密

mp4视频分片生成m3u8流文件并加密

Spring boot视频播放(解决MP4大文件无法播放),整合ffmpeg,用m3u8切片播放。

Java使用FFmpeg(自定义cmd)系列之MP4 转码 HLS m3u8 AES128 加密

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。在这里插入图片描述
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。

在这里插入图片描述

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
在这里插入图片描述

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

在这里插入图片描述

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
    

在这里插入图片描述

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

后台返回enc.key的接口

                .allowedHeaders("*")
                .exposedHeaders("token","Authorization")
        ;

dplayer切换播放视频(弹幕)

  1. 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)

  2. 必须引入DPlayer.min.css,否则弹幕无法正常显示

  3. 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)

  4. 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

  5. 弹幕返回的示例可以参考,https://s-sh-17-dplayercdn.oss.dogecdn.com/1678963.json
