如何加载正确的libavcodec.so共享库版本？ （53） [英] How to load correct libavcodec.so shared library version? (53)

问题描述

我在我的项目中使用libavcodec和libavformat，但是当我执行一个在另一台机器上构建的二进制文件时，我收到以下错误：

 加载共享库时出错：libavcodec.so.53：无法打开共享对象文件：没有这样的文件或目录
  

我使用libav安装ffmpeg并尝试以下命令：

  sudo apt-get install ffmpeg libavcodec- dev libavformat-dev 
 sudo apt-get install ffmpeg libavcodec-extra-53 
 sudo apt-get install libav-tools 
  

当我在同一台机器上构建二进制文件时，不会显示该错误，但是在第二台机器上编译会更快。

UDPATE：我也运行 sudo apt-get install update 和 sudo apt-get安装pkg-config 而不会改变输出。 （OS = 12.04）

尝试从ffmpeg安装linux二进制文件

只是为了让每个用户受益于这个答案，我添加了可用于不同平台的ffmpeg二进制文件的链接

for centOS http://pkgs.repoforge.org/ffmpeg/

安装教程：

http://ffmpegmac.net/

for Windows < a href =http://ffmpeg.zeranoe.com/builds/ =nofollow> http：//ffmpeg.zeranoe.c om / builds /

我还制作了一个视频教程来安装二进制文件。但这是在mac。但是我假设它对于linux是一样的。

希望这有助于

I am using libavcodec and libavformat in my project but when I execute a binary which was built on another machine, I get the following error:

error while loading shared libraries: libavcodec.so.53: cannot open shared object file: No such file or directory

I installed ffmpeg with libav and trying the following commands:

sudo apt-get install ffmpeg libavcodec-dev libavformat-dev
sudo apt-get install ffmpeg libavcodec-extra-53
sudo apt-get install libav-tools

The error doesnt show up when I build the binary on the same machine, but it would be much faster to compile on a second machine.

UDPATE: I also ran sudo apt-get install update and sudo apt-get install pkg-config without any change in the output. (OS = 12.04)

try installing the linux binary for ffmpeg from the above website.

just so that every user benefits from this answer i am adding links to ffmpeg binaries available for different platforms

for centOS http://pkgs.repoforge.org/ffmpeg/

Tutorial for installation :

for mac http://ffmpegmac.net/

for windows http://ffmpeg.zeranoe.com/builds/

also i have made a video tutorial to install a binary. but this is on mac. but i assume its the same for linux to.
