1. Install git. Run sudo apt-get install git-core in the command line.

2. download the latest ffmpeg version. Git clone git: // source.ffmpeg.org/ffmpeg.git ffmpeg

3. Go to the ffmpeg directory and execute./configure. At this time, the system may prompt that there is no yasm and compilation is not allowed. You can download and install yasm, and sudo apt-get install yasm can also be executed. /When configure is added, the parameter-disable-yasm is directly executed. /configure-> make install; the compiled file is put under u sr/local/bin. If you want to change the installation address, you can add the parameter -- prefix = PREFIX when executing configure.

4. After you execute./configure, a config. h file is generated,

View # define CONFIG_FFPLAY 0 if it is 0, it indicates that ffplay cannot be compiled, generally because the SDL library is missing,

Sudo apt-get install libsdl1.2-dev; Use this command to install the SDL Library

6. If no error is reported, congratulations. Execute make install.

7. Try to use ffplay to play a video. Command: ffplay videopath
