Compile FFmpeg in Ubuntu10.10

Version Ubuntu10.10, refer to some compilation methods on the Internet. 1. Download git. According to the official documentation, download and compile ffmpeg requires git implementation. Therefore, download the git command: sudoapt-getinstallgitgit-core: Update git to the latest version. Run the following command: gitclonegit: // git.kernel.org/pub/scm/git/git.git?install git=and run the following command:

Ubuntu 10.10

1. Download git. According to the official documentation, You need to download and compile ffmpeg. Therefore, download the git command:

Sudo apt-get install git-core

Run the following command to update git to the latest version:

Git clone git: // git.kernel.org/pub/scm/git/git.git

To view the installed git version, run the following command:

Git -- version

 

2. Download The ffmpeg command:

Git clone git: // source.ffmpeg.org/ffmpeg.git ffmpeg

The source code of ffmpeg has been downloaded. You can first package it into a compressed package for backup. command:

Tar czf ffmpeg.tar.gz ffmpeg/

You can directly extract the data as needed. The command is as follows:

Tar xzf ffmpeg.tar.gz

 

3. Set up the c/c ++ program environment (this is not required if it has been set up)

Install the vim Editor

Apt-get install vim

Install c/c ++ compilation tools, including "gcc, g ++, gdb, make"

Apt-get install build-essential

You can use "gcc-v" to check whether the installation is successful.

Install related tools to automatically generate makefile. command:

Apt-get install automake1.9

In this way, the dependent tools will also be installed, including autoscan, aclocal, autoconf, and automake. With these tools, you don't have to write makefile on your own in a large development project.

 

4. Install the dependent Database: command:

Sudo apt-get install subversion checkinstall yasm texi2html libfaac-dev libfaad-dev libmp3lame-dev libsdl1.2-dev libtheora-dev libx11-dev libxvidcore4-dev zlib1g-dev

Note: The dependency libraries used for compiling ffmpeg posts on the Internet are different, and I don't know what is useful.

 

 

5. Install x264 with the following command:

$ Git clone git: // git.videolan.org/x264.git

$ Cd x264
$./Configure
$ Make
$ Sudo make install

 

 

6. Compile ffmpeg

Go to the ffmpeg directory

./Configure -- enable-gpl -- enable-libmp3lame -- enable-libxvid -- enable-libfaac -- enable-nonfree -- enable-shared -- enable-static -- prefix =/usr/local/ffmpeg

Note: -- enable-shared is used to allow compilation to generate a dynamic library, so -- enable-static should be used to generate a static library, which will be used in future programming. -- Prefix setting installation directory

Note:

The final compilation is complete. There are four directories in/usr/local/ffmpeg.

Lib dynamic link library location

Header files are used for include programming.
Bin execution file directory

There is also a share folder

To facilitate programming in the future, we put the so file in lib (so file is equivalent to dynamic library file dll, o file is equivalent to the compiled target file, and a file is a static library) copy to/usr/lib. Copy the ffmpeg directory under the include directory to the/usr/include directory.

After the compilation is successful, the dynamic library must be supported during execution, and the three dynamic library files must be copied to/usr/lib or/lib, otherwise, the dynamic library link cannot be found during execution. Another way to solve this problem is to add the/usr/local/ffmpeg/lib directory to/etc/ld. so. in config, execute ldconfig, or restart the computer, so that the system can find these three dynamic library files from the directory/usr/local/ffmpeg/lib.
