编译FFMpeg-白红宇

以下为所讲解的编译ffmpeg过程，有评论说

please we need to know how to create file. i tried this and spend 8 hours downloading installing ubuntu,installing updating sudo git, installing python,making toolchains, and at last making a ffmpeg build for all arms ffmpeg 4.0, but now it is useless without . your tutorial is the best bytheway.

环境

python版本 -2.7android ndk 下载最新稳定ffmpeg 下载最新稳定编写build files ，使用独立编译工具链复制代码

ndk自带的编译链工具

android ndk download 【google搜索】

生成不同架构的编译链

关于工具链的理解可以查看

开始编译

最后粘贴一下本人使用的编译工具链

拓展

根据可以下载“Termux” 【一个命令行工具】来使用ffmpeg命令行。

一共执行了三个步骤

apt updateapt upgradeapt install ffmpeg# 之后就可以使用ffmpeg的命令了，egffmpeg -versionffmpeg -help# 当然你可以使用这个工具不止干这些事情#下载其他工具复制代码

也有人写了开源的工程，可以直接用androidapk来执行ffmpeg的命令，只是不知道怎么替换ffmpeg的so，这个作为了解
