EasyMedia

介绍

Springboot、netty实现的http-flv、websocket-flv流媒体服务(可用于直播点播),支持rtsp、h264、h265等、rtmp等多种源,h5纯js播放(不依赖flash),不需要依赖nginx等第三方,由于全部经过转码,延迟大部分在3-5秒左右(如果转封装可以在2-3秒左右,需自行修改)。

前端源码传送门

软件架构

  • netty负责播放地址解析及视频传输,通过javacv推拉流存到内存里,直接通过输出到前端播放
  • 后端:springboot、netty,集成websocket
  • 前端:vue、html5(简单的管理页面)
  • 播放器:西瓜播放器 http://h5player.bytedance.com/ (字节跳动家的,不介绍了,抖音视频、西瓜视频都杠杠的,当然只要支持flv的播放器都可以)
  • 媒体框架:javacv、ffmpeg

使用教程

流媒体服务会绑定两个端口,分别为 8866(媒体端口)、8888(web端口,后续会做简单的管理页面) 您只需要将 {您的源地址} 替换成您的,然后放播放器里就能看了

  • 播放地址(播放器里直接用这个地址播放)
http://localhost:8866/live?url={您的源地址}
ws://localhost:8866/live?url={您的源地址}
例如rtsp:
http://localhost:8866/live?url=rtsp://admin:VZCDOY@192.168.2.84:554/Streaming/Channels/102
ws://localhost:8866/live?url=rtsp://admin:VZCDOY@192.168.2.84:554/Streaming/Channels/102
文件(支持格式参照ffmpeg支持的格式):
http://localhost:8866/live?url=d:/flv/testVideo.mp4
ws://localhost:8866/live?url=d:/flv/testVideo.mp4
  • 推拉流(有两种方式)
  1. 按需播放(默认)直接使用上面播放地址就可以播放,每次第一个用户打开会创建推流,没人看时十几秒后会自动断开流。
  2. 永久播放,通过restfu api或者页面先新增流,再开启推流,在服务同级目录会生成一个camera.json,重启服务发现camera.json也会自动推流,用json文件是方便手动维护源地址,之后通过播放地址可以在浏览器直接秒开。
永久播放还有一种捷径,就是在播放地址后面加上autoClose=false参数,也会加入到json中。
例如:
http://localhost:8866/live?url=rtsp://admin:VZCDOY@192.168.2.84:554/Streaming/Channels/102&autoClose=false
ws://localhost:8866/live?url=rtsp://admin:VZCDOY@192.168.2.84:554/Streaming/Channels/102&autoClose=false
  • 页面功能
可以访问 http://localhost:8888
具体功能参照截图
  • restful api
新增流 http://localhost:8888/add?url={您的源地址}&remark={备注}
停止并删除 http://localhost:8888/del?url={您的源地址}
停止推流 http://localhost:8888/stop?url={您的源地址}
开始推流 http://localhost:8888/start?url={您的源地址}
查看保存的流 http://localhost:8888/list
  • 成品运行方式(由于是跨平台的,未做ffmpeg精简,所以包会比较大)
java -jar EasyMedia-0.0.1-SNAPSHOT.jar
还可以这样改端口
java -jar -Dserver.port=页面端口 -Dmediaserver.port=媒体端口 EasyMedia-0.0.1-SNAPSHOT.jar

疑问解答

  • 在vlc、ffplay等播放器测试存在延迟较高是正常的,是因为他们默认的嗅探关键帧的时间比较长,测延迟建议还是用flv.js播放器测试。
  • 是否需要ffmpeg推流,不需要,就是为了简化使用,只需运行一个服务即可。
  • 很多人想用文件点播,可以参考截图。

源码教程

  1. 环境:java8+
  2. 标准的maven项目,sts、eclipse或者idea导入,直接运行main方法

更新说明 2021-03-14

  • 新增简单的web页面管理
  • 优化自动断开
  • 新增服务端自动重连
  • 支持本地文件点播
  • 支持启动服务自动推流
  • 支持音频转码
  • 启动服务前初始化资源(防止第一次启动慢)
  • 新增保存数据到同级目录的camera.json

更新说明 2021-02-20

  • 移除原有spring websocket,采用高性能的netty作为http、ws服务。
  • 完善关闭流逻辑,没人看时会自动断开。
  • 由于替换netty,考虑到视频文件需要上传到服务器,所以暂时移除本地文件支持。

网上找的测试地址 安徽卫视,建议用自己内网的,公开的可能速度就比较慢

为什么要写个这个

现在flash已经被抛弃,h5播放的时代,网上实现大多不是特别完整的(比如拿到一个rtsp或者rtmp,也不知道怎么在h5页面直接播放),当然现在直播点播有很多方式,可以通过nginx带flv模块的当rtmp服务、还有srs等流媒体服务,而这里我们通过javacv来处理,事实上javacv性能足够,底层ffmpeg也是通过c实现,使用java调用c跟使用c++去调用c差不了多少毫秒延迟。java流媒体资料比较少,但从应用层来说,java有着庞大的生态优势,配合netty写出的流媒体性能可想而知,而此源码目前也比较简单,可读性比较强,有能力者完全能自主改成java分布式流媒体。随着人工智能图像识别的发展,从流媒体获取图像数据是必要条件,有bug希望你们也能及时提出。

最后感谢eguid的javacv文档,https://eguid.blog.csdn.net/

后续计划

  • 完善web管理页面,方便管理点播文件和播放列表等
  • 增加录制功能
  • 由于hls(m3u8)兼容性最好,水果、安卓和PC通吃,所以后续会加入m3u8切片方式
  • 原本还写了个通过ffmpeg子进程推流,然后用socket服务接收的方案,等javacv版搞完善了再弄。
  • 没想到这项目会有这么多人用,我会抽空慢慢维护。
