• Cross-compiling for ffmpeg : libvpx decoder version must be >=0.9.1

  13 octobre 2016, par bot1131357

  (Note : I know the title is almost identical to this question, but its solution is only applicable if I were building on my own system. I am building for an embedded ARM device.)

  I am trying to build a cross-compile FFmpeg library to be targeted on an arm device, and the ./configure command tells me that libvpx is outdated.

  My version of libvpx is as follows :

  $ pkg-config --modversion vorbis 
  
  1.3.2

  When I run ./configure

  $ ./configure --prefix=/home/test/Dev/build-arm/ffmpeg-armhf/ --enable-cross-compile --cross-prefix=${CCPREFIX} --arch=armhf --target-os=linux --pkg-config-flags="--libs vpx --static --cflags" --enable-shared --enable-libvpx 
  
  ERROR: libvpx decoder version must be >=0.9.1
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solve the problem.

  My vpx.pc file is located in /usr/share/pkgconfig. Since it’s for a different target (arm), Should I be putting this file somewhere else ? :

  # pkg-config file from libvpx v1.6.0-322-gc325fb7
  
  prefix=/home/test/Dev/build-arm/libvpx
  
  exec_prefix=${prefix}
  
  libdir=${prefix}/lib
  
  includedir=${prefix}/include
  
  
  
  Name: vpx
  
  Description: WebM Project VPx codec implementation
  
  Version: 1.6.0
  
  Requires:
  
  Conflicts:
  
  Libs: -L${libdir} -lvpx -lm
  
  Libs.private: -lm -lpthread
  
  Cflags: -I${includedir}

  In my config.log I see this :

  It looks like the include and library paths are not provided to the compiler, but I don’t know how I should go around solving that.
  I would really appreciate it if you could offer some guidance.

• Can't use latest FFMpeg-PHP because my newly installed FFProbe does not support loglevel and quiet

  20 septembre 2016, par Richard Mcfriend Oluwamuyiwa

  Please I just installed ffmpeg and ffmpeg-php using brew install on my OS X 10.10 but i can’t use the FFMpeg-PHP because my FFProbe does not support '-loglevel' and 'quiet' options.

  I get this error from

  Fatal error: Uncaught Symfony\Component\Process\Exception\RuntimeException: The process has been signaled with signal "5"

  I just installed it tonight using

  brew install ffmpeg ....

  My composer.son is

  {
  
      "require": {
  
          "php-ffmpeg/php-ffmpeg": "~0.5"
  
      }
  
  }

  And I just installed the Composer too using the instruction on their website. And when I run composer, I get version 1.2.1 which is the latest.

  I am trying to run the FFMpeg demo code :

  require __DIR__ . '/vendor/autoload.php';
  
  
  
  $ffmpeg = FFMpeg\FFMpeg::create(array(
  
      'ffmpeg.binaries'  => '/usr/local/bin/ffmpeg',
  
      'ffprobe.binaries' => '/usr/local/bin/ffprobe',
  
      'timeout'          => 3600, // The timeout for the underlying process
  
      'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
  
  ));
  
  $video = $ffmpeg->open('video.mp4');
  
  
  
  $video
  
      ->filters()
  
      ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
      ->synchronize();
  
  
  
  $video
  
      ->frame(FFMPeg\Coordinate\TimeCode::fromSeconde(10))
  
      ->save('frame.jpg');
  
  
  
  $video
  
      ->save(new FFMpeg\Format\Video\X265(), 'ff-video-x264.mpg')
  
      ->save(new FFMpeg\Format\Video\WMV(), 'ff-video-wmv.wmv')
  
      ->save(new FFMpeg\Format\Video\WebM(), 'ff-video-webm.webm');

  Any help is appreciated. I really need it working for a project.

• Updating ffmpeg on Ubuntu 12.04 ; conflicts with old version from standard repository

  29 octobre 2016, par Frank van Wensveen

  I have never used ffmpeg on my Ubuntu Linux 12.04 (Precise Pangolin) box until now. Typing ’ffmpeg’ at the command prompt revealed that ffmpeg 0.8.17 (listed as ffmpeg 0.8.17-4:0.8.17-0ubuntu0.12.04.2) was installed. Seeing as I need to convert h.265 to h.264, an update was obviously required.

  Following posted instructions, I installed a ream of packages :

  $ sudo apt-get install faad libmp4v2-dev libfaac0 libfaac-dev
  
  libxvidcore4 libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev
  
  libgsm-tools libogg-dev libtheora-bin libfaad-dev libvorbis-dev 
  
  libtheora-dev libdts-dev git-core yasm texi2html checkinstall

  followed by

  $ sudo apt-get purge ffmpeg

  in order to get rid of the old stuff from the original repo.

  Downloaded the latest ffmpeg, and a ."/configure ; make ; sudo make install" later, I should be in business.

  Except that typing ’ffmpeg’ at the prompt still fired up the old version. A quick look revealed that the old ffmpeg binary was still sitting in /usr/bin with the new one being installed in /usr/local/bin. But ffmpeg is no longer listed as an installed package, and sudo apt-get remove ffmpeg tells me that "Package ffmpeg is not installed, so not removed".

  Running /usr/local/bin/ffmpeg directly works, however then fails in an Unknown encoder ’libx264’ error. Which is puzzling because the package libx264-120 is installed and /usr/lib/i386-linux-gnu/libx264.so.120 (with the appropriate symlink to /usr/lib/i386-linux-gnu/libx264.so) does exist.

  Maybe I’ve been looking at this for too long, because I’m sure this is a simple issue but I just can’t see it.

  Can someone please hand me the stupid had and point out why I deserve to wear it ?

  Tnx !
