Documentation

Windows environment setup

• Go to the official ffmpeg to download the compiled Windows shared library;
  • Official website: https://ffmpeg.org/
• Copy the executable file ffmpeg.exe ffplay.exe ffprobe.exe to the C:\Windows directory;
• Copy the corresponding dynamic library to the C:\Windows\SysWOW64 directory;
  • 注：WOW64 (Windows-on-Windows 64-bit)
• Enter ffmpeg -version in the command line window to check the version, but to confirm whether the environment is successfully built

[Configuration environment ubuntu desktop 16.04 + ffmpeg 4.2.1]

Linux environment construction

Create a directory

• Created in the home directory
• ffmpeg_sources: used to download source files
• ffmpeg_build: store compiled library files
• bin: store binary files (ffmpeg, ffplay, ffprobe, X264, X265, etc.)

cd ~

mkdir ffmpeg_sources  ffmpeg_build bin

PATH="$HOME/bin:$PATH" make && \
make install

libfdk-aac

• AAC Audio Encoding. For more information and usage examples, refer to AAC Audio Encoding Guide .
• Configure when compiling ffmpeg: --enable-libfdk-aac (if you have already configured --enable-gpl, you need to add --enable-nonfree).

cd ~/ffmpeg_sources && \
git -C fdk-aac pull 2> /dev/null || git clone --depth 1 https://github.com/mstorsjo/fdk-aac && \
cd fdk-aac && \
autoreconf -fiv && \
./configure --prefix="$HOME/ffmpeg_build" --disable-shared && \
make && \
make install

libmp3lame

• MP3 audio encoder.
• Configure when compiling ffmpeg: --enable-libmp3lame.

cd ~/ffmpeg_sources && \
git clone  --depth 1 https://gitee.com/hqiu/lame.git && \
cd lame && \

hash -r

• Then log in to the system again or execute the following command in the current shell session to identify the location of the newly installed ffmpeg:

source ~/.profile

• After compilation, the general situation of ffmpeg_build ffmpeg_sources bin directory

lqf@ubuntu:~/ffmpeg_build$ ls
bin  include  lib  share

lqf@ubuntu:~/ffmpeg_sources$ ls
fdk-aac               lame-3.100.tar.gz     opus        yasm-1.3.0.tar.gz
ffmpeg-4.2.1          libvpx                x264
ffmpeg-4.2.1.tar.bz2  nasm-2.14.02          x265
lame                  nasm-2.14.02.tar.bz2  yasm-1.3.0

lqf@ubuntu:~/bin$ ls
ffmpeg  ffplay  ffprobe  lame  nasm  ndisasm  vsyasm  x264  yasm  ytasm

use

• Now, you can open a terminal, enter the ffmpeg command, and it should execute the new ffmpeg.
• If you need multiple users to use your newly compiled ffmpeg at the same time, you can move or copy the ffmpeg binary file from ~/bin to /usr/local/bin.

Documentation

• You can use man ffmpeg to access the document locally:
  • echo "MANPATH_MAP $HOME/bin $HOME/ffmpeg_build/share/man" >> ~/.manpath
• You may have to log out of the system and then log back in to man ffmpeg to take effect.
• The documentation in HTML format is located at  ~/ffmpeg_build/share/doc/ffmpeg .
• You can refer to the online FFmpeg documentation .
