• Configured Half-ninja android FFMPEG project

  24 décembre 2013, par Mr.G

  I have configured android-halfninja project completely and i manage to build

  refered to this link

  libs/armeabi/libvideokit.so and
  libs/armeabi/ffmpeg

  libs from the given source

  But i had to make some changes to the .sh files in order to build .so files.

  But now i tried to execute following ffmpeg command in my android project it doesn't run properly

      String var[] = {"ffmpeg","-i",input};

• convert ogv to webm using ffmpeg and point ffmpeg to new installed version

  9 juin 2015, par Aisha

  I was facing problem in converting files from one format to another, so I put the question on stackoverflow, some people suggested me to recompile ffmpeg my ffmpeg version was 0.10.0 so they suggest me to install new one with full codecs from this link

  https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

  I followed the steps and installed new version but i didnot uninstall my old one and its still giving me error when i am converting video from ogv to webm

• Enabling libmp3lame for FFMPEG on elastic beanstalk

  13 octobre 2017, par Adam Sith

  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.
