Enabling libmp3lame for FFMPEG on elastic beanstalk

I am trying to enable libmp3lame with FFMPEG in elastic beanstalk (Amazon Redhat Linux machine).

I am able to successfully install FFMPEG in /ffmpeg.config with the following script:

# .ebextensions/ffmpeg.config

packages:
  yum:
    autoconf: []
    automake: []
    cmake: []
    freetype-devel: []
    gcc: []
    gcc-c++: []
    git: []
    libtool: []
    make: []
    nasm: []
    pkgconfig: []
    zlib-devel: []
sources:
  /usr/local/src: http://ffmpeg.org/releases/ffmpeg-3.2.tar.bz2
commands:
  ffmpeg_install:
      cwd: /usr/local/src/ffmpeg-3.2
      command: sudo ./configure --prefix=/usr && make && make install

I need to install libmp3lame however. I’ve tried to do this with an --enable-libmp3lame flag and the directions here. The modified script:

packages:
yum:
    autoconf: []
    automake: []
    cmake: []
    freetype-devel: []
    gcc: []
    gcc-c++: []
    git: []
    libtool: []
    make: []
    nasm: []
    pkgconfig: []
    zlib-devel: []
sources:
  /usr/local/src: http://ffmpeg.org/releases/ffmpeg-3.2.tar.bz2
commands:
  01-install_libmp3lame:
      cwd: /usr/local/src/
      command: curl -L -O http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz && tar xzvf lame-3.99.5.tar.gz && cd lame-3.99.5 && ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --disable-shared --enable-nasm && make && make install
  02-ffmpeg_install:
      cwd: /usr/local/src/ffmpeg-3.2
      command: sudo ./configure --enable-libmp3lame && --prefix=/usr && make && make install

This doesn’t work. Command 01-install_libmp3lame completes. Command 02-ffmpeg_install fails because:

[2017-10-12T20:55:19.324Z] INFO  [24606] - [Application update app-8fe3-123456_7895@111/AppDeployStage0/EbExtensionPreBuild/Infra-EmbeddedPreBuild/prebuild_3_clover_platform/Command 02-ffmpeg_install] : Activity execution failed, because: ERROR: libmp3lame >= 3.98.3 not found

I have tried installing libmp3lame in /ffmpeg-3.2 and got the same issue.

Answer

1. You used --prefix="$HOME/ffmpeg_build", but you didn’t tell ffmpeg to look there for it. You can omit this and it will probably use /usr/local/ by default.

2. You are trying to run --prefix=/usr as an independent command instead of part of your ffmpeg ./configure. You can omit this.

3. If you’re going to use a release branch of ffmpeg instead of the git snapshot you should use the latest version which is currently 3.3, not 3.2. However, 3.4 is due very soon (within days or a week I’m guessing).

4. No need for sudo to configure, but you may need it for make install depending on your system and user.

Below are commands you can adapt. I didn’t verify the paths are correct to the directories containing the source for lame and ffmpeg.

cd lame-3.99.5
make uninstall
make distclean
./configure --disable-shared --enable-nasm
make
make install
cd ../ffmpeg
make uninstall
cd ../
rm -f ffmpeg
curl -O http://ffmpeg.org/releases/ffmpeg-3.3.4.tar.bz2
cd ffmpeg
./configure --enable-libmp3lame
make
make install
