#将x86_64/transfer.tar.gz解压至根目录
$sudo tar xzvf x86_64/transfer.tar.gz -C /
etc/config/transfer
etc/init.d/transfer
usr/sbin/transfer
#将transfer服务更新至系统

#卸载
$sudo /usr/sbin/update-rc.d -f collector remove 
#运行
$sudo service collector start|stop|restart|status

install keepalive

测试

如果没有特殊说明，请使用工具包中的ffmpeg

  • 直接用ffmpeg中转
    • ffmpeg -re -i /opt/public/1.ts -vcodec h264 -acodec mp3 -f mpegts udp://127.0.0.1:12344
    • ffmpeg -re -i udp://127.0.0.1:12344 -vcodec copy -acodec copy -f mpegts udp://127.0.0.1:12345
  • 模拟输入/转码
    • while true ; do ffmpeg -re -i /opt/public/1.ts -vcodec h264 -acodec mp3 -f mpegts udp://127.0.0.1:12345 ; done
  • transfer
    • transfer
    • sudo service transfer start|stop|restart
  • collector
    • collector
    • sudo service collector start|stop|restart
  • 模拟接收
    • ffplay -af 'volume=0.0' udp://127.0.0.1:12347
  • 生成带标记帧的ts文件
    • ffmpeg -re -i /tmp/in.mp4 -vcodec h264 -acodec mp3 -strict experimental -f mpegts -vf scale=-1:540 /tmp/out.ts
  • 多网卡情况下的多播路由设置
    • sudo route add -net 224.0.0.0/8 vmnet1

高可用 keepalived

配置文件是/etc/keepalived/keepalived.conf,修改配置后，需要重启服务sudo service keepalived restart

! Configuration File for keepalived

vrrp_script chk_echo_port {
    script "echo '</dev/tcp/127.0.0.1/12346' | /bin/bash" #检测本地的tcp 12346端口
    interval 1
	weight -2             #如果失败，权重-2
}

vrrp_instance VI_1 {      #广播域内的名称VI_1
    state BACKUP
    interface eth0        #这里填写内网（ha）广播接口设备名
	track_interface {
		eth0              #同上，如果eth0异常，会触发notify_fault
	}
    virtual_router_id 51
    priority 100          #权重，backup的权重高于master时，会与master交换角色身份
    advert_int 1
    authentication {
        auth_type PASS    #认证类型及口令，同一广播域内的相同id，口令须一致
        auth_pass 1111
    }
    track_script {
       chk_echo_port      #脚本检查，会影响权重
    }
    notify_backup "/etc/keepalived/backup.sh"  #切换至backup时触发
    notify_master "/etc/keepalived/master.sh"  #切换至master时触发
    notify_fault  "/etc/keepalived/fault.sh"   #网卡检查失败时触发
    notify_stop   "/etc/keepalived/stop.sh"    #服务关闭时触发

}

转码常用参数

ffmpeg -re -i /opt/public/1.ts -vcodec h264 -acodec mp3 -f mpegts -preset veryfast -vf scale=640*360  -crf 28  udp://172.16.0.115:12348
  • preset Current presets in descending order of speed are:
    • ultrafast
    • superfast
    • veryfast
    • faster
    • fast
    • medium
    • slow
    • slower
    • veryslow
    • placebo
  • vf scale=640*360
  • crf The range of the quantizer scale is 0-51: where 0 is lossless, 23 is default, and 51 is worst possible.

其他

  • 测试版本在运行一个小时后会进入一个小时的睡眠状态,可以手动重启解决
  • 工具包中的ffmpeg版本和public目录下的ts文件,是修改过,带有标记帧信息的
  • 开发进度sender
  • 部署拓扑transfer
