  • 根据查资料所知,设置GCC的安全的CFLAGS指令选项是-O2 -pipe -march=armv6 -mfpu=vfp -mfloat-abi=hard,还可以试一下这个-march=armv6zk -mtune=arm1176jzf-s -mfloat-abi=soft

0x2 编译ffmpeg依赖软件包

  • 下面先要编译安装一些依赖的库,这里用到的x264,libmp3lame,编译的过程出现任何问题,要查看config.log分析处理解决.假设编译安装的目是/home/user 具体可以自己更改.如果编译的东西非常多,会需一个个按依赖顺序逐个编译,如果动态库还要考虑与原系统里的库是ABI兼容的,GCC的版本也是要统一的,如果编译成静态库可以考虑使用该方法.
  • 也可以用另一个方法,在RPi安装好相关的一些库如:sudo apt-get install libssl1.0-dev libbz2-1.0 libmbedcrypto3 libmbedtls-dev nettle-dev libbz2-dev,安装完成之后,把RPi里的系统卡挂载到编译机上面去,指定--sysroot为这个RPi的根系统顶层目录,本文的RPi使用的系统是Raspbian 10,挂载的位置是/media/michael/rootfs,所以要指定--sysroot=/media/michael/rootfs,编译完成后安装路径可以指定为--prefix=/media/michael/root/usr/local.
  • 如果直接使用一张安装了RPi的SD卡挂载做交叉编译的sysroot,需要处理卡里文件系统的一些绝对引用链接文件,它在RPi系统理正常,具体可以参考这里,ffmpeg编译配置前检测到一些系统库的链接是broken,就会认为是没有这个库,在实际会出现ffmpeg无法开启pthread的特性支持.下面是处理它的脚本.

RTMP支持

  • rtmpdump这个库有很久没有更新了,如果要使用加密功能,需一些加密库来支持,且它的编译不像是上面的x264,zlib那样,它需要指定--sysroot才能正确的编译与链接原系统的库.

0x3 下载并编译FFMPEG

硬件加速相关

  • 如--enable-decoder=h264_mmal --enable-mmal是需要mmal.h头文件的,--enable-encoder=h264_omx --enable-omx --enable-omx-rpi
    这些是要Openmax的头文件的.原本以为要下载OpenMAX IL头文件,后来发现这一步是不需要的,所有硬件开发的支持文件在RPi里的/opt/vc下面.

  • 如需开启--enable-opengl,需要在RPi安装gl库,如:libopengl-dev libgles-dev libgl-dev libegl-dev libopengl0 libgles2 libgles1.

  • 如果开启drawtext过滤器,也就是往视频上写字,需要加上--enable-libfreetype --enable-libfontconf --enable-libfribidi选项,要先行安装
    libfribidi-dev libfontconfig1-dev libfontconfig1的运行库与头文件.

  • 这里最好新建一个目录用来编译,防止在当前目录下编译污染了当前目录.

  • 从ffmpeg仓库发现,release/3.4之后无法支持omx硬件加速功能,4.2之后会报WARNING: Disabled h264_omx_encoder because not all dependencies are satisfied: omx的提示警告.

编译Libwebsockets,mosquitto支持IPv6

  • 在RPI里可以直接安装发行版的mosquitto,libwebsockets库与服务,但是发现在发行版里的libwebsockets没有开启IPv6支持,导致mosquitto里的websockets协议服务,只有IPv4的服务,编译安装仅仅只为了让它支持IPv6.

  • 如下面错误所示,就是有一个变量没有初始化,可能是这个GCC版本也没有相应处理机制,所以报错了,打开源码找到出错位置,给变量设置一个初值.

0x5 内网转发

SSH转发

  • 如果自己有公网的IP或者VPS,可以通SSH远程转发的方式,把本地HLS流服务暴露出去.这里要确保VPS里的sshd_config有GatewayPorts=yes这一行,不然SSH服务器只能绑定localhost:8080.下面命令成功后,可以通过http://<vps-domain>:8080访问里内网里的HLS服务了.
1
~$ sudo ssh -NfC -R 8080:localhost:80 user@<vps-domain>

ngrok转发

  • ngrok是一个内网穿透服务,需要注册才能使用,免费版帐号只能运行一个且有功能限制的实例.它在github的源码已经不更新,不过自己可以使用该源码搭建自己的私服.

  • 它的使用也相当的容易,无须配置.先注册子一个帐号,再下载一个对应平台的ngrok客户端程序.在须要转发的内网机内,添加帐号里的Authtoken.

IPv6-PD(Prefix Delegation)模式,动态域名直连

  • 这里就使用dynv6.com的免费域名.注册帐号->激活帐号->创建域名.会创建一个WAN_6的接口,同时会从ISP获得一个IPv6公网地址与IPv6-PD的前缀.

  • 如果是用NAT6的模式,需要在OpenWRT编译源码时,需选择上iptables-nat6,转发DNAT与IPv4下的NAT是一样的原理.确保安装了dhcpcd5 - DHCPv4, IPv6RA and DHCPv6 client with IPv4LL support,安装完成dhcpcd5后启动systemctl start dhcpcd5.

  • 或者使用下面脚本,如:请求wlan0的IPv6地址.

	dhcpcd wlan0
fi
EOF
~# chmod +x /etc/network/if-up.d/dhcpcd
  • 或者在/etc/network/interfaces里加入post-up.

	IPV6=$(ip -6 addr list scope global eth0 | grep -v " fd" | sed -n 's/.*inet6 \([0-9a-f:]\+\).*/\1/p' | head -n 1)/128
else
	IPV6=$(ip -6 addr list scope global wlan0 | grep -v " fd" | sed -n 's/.*inet6 \([0-9a-f:]\+\).*/\1/p' | head -n 1)/128

  • Luci--> Network--> Firewall--> Traffic Rules里添加一条规则,通过IPv6地址访问它的80端口,在配置文件里显示如下:

root@OpenWrt:~# cat /etc/config/firewall

config rule

	option name 'camera'
	option target 'ACCEPT'
	option family 'ipv6'
	option dest 'lan'
	list proto 'tcp'
	option dest_port '80'

  • 如果使用NAT6,且ip6tables -P INPUT ACCEPT话,默认公网就可以通过路由器的IPv6地址,直接访问到路由的80端口,所以这里把nginx服务改成listen [::]:8888 default_server;.

  • 因为是公网可以了访问,可以在系统里安装防火墙脚本apt-get install ufw.

  • 定时刷新DDNS的地址,并且定时刷新OpenWrt里的防火墙规则,否则无法转发端口到内网访问。
