[树莓派]aarch64编译静态的ffmpeg 可硬解h264/hevc

Posted 2021-09-10 member

• 系统 openfans aarch64
• 树莓派4B
• docker

此方法特点

• 不污染现有的系统(编译在docker中), 因为各种依赖库会占用掉2G左右空间。

  没有洁癖的可以参考作者上一篇文章: aarch64 系统 编译最新的ffmpeg 并支持硬解h264

• 编译出来的文件是静态的, 也就是无需安装任何依赖就可以运行在aarch64系统上
• 支持h264_v4l2m2m的GPU硬解输出, CPU占用极低, 解码速度也很快.
• 如果使用同样的参数用CPU解码, 4核CPU均在40%~60%左右, 而v4l2m2m只需要1核的20% 省下很大的CPU用量
• 在640x480的分辨率下, 上传至rtsp直播服务器端, 使用potplayer播放, 延时在200ms左右, 基本上叫同步
• 解决了v4l2m2m2黑屏的BUG, 原git里面直接编译就有这个问题, https://johnvansickle.com/ffmpeg/下载的静态文件也有此BUG

编译

启动ubuntu干净的容器

docker run -u root -it --privileged -v /dev/:/dev/ ubuntu bash

脚本

为了保险起见, 需要一个块一个块的贴到控制台去执行

主要问题是部分文件网络无法访问, 需要自行设置代理export https_proxy=http://your.proxy. ip:port

apt update
apt install -y ca-certificates

export DEBIAN_FRONTEND=noninteractive
cp /etc/apt/sources.list /etc/apt/sources.list.bak
echo -e \'deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal main restricted universe multiverse\\ndeb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-updates main restricted universe multiverse\\ndeb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-backports main restricted universe multiverse\\ndeb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-security main restricted universe multiverse\' > /etc/apt/sources.list

apt update
apt install -y build-essential cmake meson sudo pkg-config autopoint automake libtool
apt install -y libxvidcore-dev git wget

关键参数
没有这2个参数是无法编译出静态执行文件的

作者也是尝试了试验了各种方法, 编译不下10次才制作出静态文件(编译一次20~30余分钟)

--pkg-config-flags="--static" \\
--extra-ldexeflags="-static" \\

生成的文件

~/FFmpeg下的ffmpeg就是静态的可执行文件, 复制到aarch64系统上就可以直接运行
