FFmpeg下载及安装

2022年7月11日

https://ffmpeg.zeranoe.com/builds/ 网站挂了

一、 FFmpeg下载 1.1 windows方法一

https://ffmpeg.org/download.html#build-windows

ffmpeg-4.4.1-full_build.7z 、ffmpeg-4.4.1-full_build-shared.7z 区别：

1. ffmpeg-4.4.1-full_build.7z:版本只包含了ffmpeg.exe、ffplay.exe、ffprobe.exe三个可执行程序，没有头文件和库文件。
2. ffmpeg-4.4.1-full_build-shared.7z exe:版本包含了ffmpeg.exe、ffplay.exe、ffprobe.exe三个可执行程序和相关动态库文件,包含了头文件和库文件。

1.2 windows方法二

zeranoe编译FFmpeg挂了 ，可以访问 FFmpeg-Builds。

ffmpeg-n4.4-latest-win64-gpl-shared-4.4.zip
目标平台：win64

• 参数说明

  Available targets:

  • win64 (x86_64 Windows)
  • win32 (x86 Windows)
  • linux64 (x86_64 Linux, glibc>=2.23, linux>=4.4)
  • linuxarm64 (arm64 (aarch64) Linux, glibc>=2.27, linux>=4.15)

  The linuxarm64 target will not build some dependencies due to lack of arm64 (aarch64) architecture support or cross-compiling restrictions.

  • davs2 and xavs2: aarch64 support is broken.
  • libmfx and libva: Library for Intel QSV, so there is no aarch64 support.

  Available:

  • gpl Includes all dependencies, even those that require full GPL instead of just LGPL.
  • lgpl Lacking libraries that are GPL-only. Most prominently libx264 and libx265.
  • nonfree Includes fdk-aac in addition to all the dependencies of the gpl variant.
  • gpl-shared Same as gpl, but comes with the libav* family of shared libs instead of pure static executables.
  • lgpl-shared Same again, but with the lgpl set of dependencies.
  • nonfree-shared Same again, but with the nonfree set of dependencies.

  All of those can be optionally combined with any combination of addins.

  • 4.4 to build from the 4.4 release branch instead of master.
  • 5.0 to build from the 5.0 release branch instead of master.
  • debug to not strip debug symbols from the binaries. This increases the output size by about 250MB.

1.3 Linux下载安装 二、 FFmpeg安装 2.1 windows下安装

# 解压后将/bin 文件夹添加系统环境变量
ffmpeg -version

2.2 Linux下安装 三、测试 3.1 FFmpeg安装目录

FFmpeg安装目录如下，将include和lib文件夹copy 项目文件中；

# FFmpeg 安装目录文件结构
├─bin
├─doc
├─include
│  ├─libavcodec
│  ├─libavdevice
│  ├─libavfilter
│  ├─libavformat
│  ├─libavutil
│  ├─libpostproc
│  ├─libswresample
│  └─libswscale
├─lib
└─presets

3.2 新建项目测试

1. QT --> Projects-->New--> 选择Plain C++ Application

2. 从FFmpeg安装目录如下，将include和lib文件夹copy 项目文件中，.pro添加ffmpeg的include和lib文件夹

INCLUDEPATH += $$PWD/include
LIBS += $$PWD/lib/avformat.lib   
        $$PWD/lib/avcodec.lib    
        $$PWD/lib/avdevice.lib   
        $$PWD/lib/avfilter.lib   
        $$PWD/lib/avutil.lib     
        $$PWD/lib/postproc.lib   
        $$PWD/lib/swresample.lib 
        $$PWD/lib/swscale.lib

3. FFmpeg测试输出版本信息

#include 

// 包含ffmpeg头文件
#include "libavutil/avutil.h"

int main()
{
    printf("Hello FFMPEG, av_version_info is %sn",
           av_version_info());

    printf("avutil_configuration is n%sn",
           avutil_configuration());

    return 0;
}

4. FFmpeg测试结果输出
