• How to convert video for web with ffmpeg for Twitter [closed]

  25 janvier 2024, par Alex Nox

  ffmpeg -i "sabaer.avi" -r -crf 23 -c:v libx264 sabe2r.mp4
Doesn't work
The media you tried to upload was invalid.

  


  Using this converter although fixes the problem :

  But it's not a vertical video format there and I originally want to do it via ffmpeg

  


• Compile FFmpeg with libfdk_aac

  18 février 2017, par Toydor

  I been reading on how to convert mp3 to m4a, and found that I must compile FFmpeg if I’ll use the AAC encoder, libfdk_aac.

  But reading FFmpeg guide on how to compile FFmpeg with libfdk_aac makes no sense for a beginner like me.

  To use libfdk_aac the encoding guide says :

  Requires ffmpeg to be configured with —enable-libfdk_aac
  —enable-nonfree.

  Where do I put those flags ?

  Do I put it here somewhere ? :

  cd ~/ffmpeg_sources
  
  git clone --depth 1 git://github.com/mstorsjo/fdk-aac.git
  
  cd fdk-aac
  
  autoreconf -fiv
  
  ./configure --prefix="$HOME/ffmpeg_build" --disable-shared
  
  make
  
  make install
  
  make distclean

  Or maybe here somewhere ?

  cd ~/ffmpeg_sources
  
  git clone --depth 1 git://source.ffmpeg.org/ffmpeg
  
  cd ffmpeg
  
  PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig"
  
  export PKG_CONFIG_PATH
  
  ./configure --prefix="$HOME/ffmpeg_build" \
  
    --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
  
    --bindir="$HOME/bin" --extra-libs="-ldl" --enable-gpl --enable-libass --enable-libfdk-aac \
  
    --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx \
  
    --enable-libx264 --enable-nonfree --enable-x11grab
  
  make
  
  make install
  
  make distclean
  
  hash -r

  If I’m reading the compile guide right I guess that these two chunks of code is what I need to compile FFmpeg.

  I’m using Ubuntu server 12.4

  UPDATE

  After upgrading my system to Ubuntu 16.04 I had to install ffmpeg again.
  I still needed libfdk-aac. Fortunately there’s a good step-by-step guide at http://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu on how to compile ffmpeg.

  I thought I would share how to compile if just interested in compiling ffmpeg with libfdk-aac and libmp3lame.

  If you haven’t already a bin in home directory :

  mkdir ~/bin 

  Install dependencies. Didn’t need the non-server packages :

  sudo apt-get update
  
  sudo apt-get -y install autoconf automake build-essential libass-dev libfreetype6-dev libtheora-dev libtool libvorbis-dev pkg-config texinfo zlib1g-dev 

  Then install the encoders. Had to install yasm as well, otherwise I got errors when compiling.

  sudo apt-get install libfdk-aac-dev
  
  sudo apt-get install libmp3lame-dev
  
  sudo apt-get install yasm

  Then compile ffmpeg with needed flags

  cd ~/ffmpeg_sources
  
  wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
  
  tar xjvf ffmpeg-snapshot.tar.bz2
  
  cd ffmpeg
  
  PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
  
  --prefix="$HOME/ffmpeg_build" \
  
  --pkg-config-flags="--static" \
  
  --extra-cflags="-I$HOME/ffmpeg_build/include" \
  
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
  
  --bindir="$HOME/bin" \
  
  --enable-libass \
  
  --enable-libfdk-aac \
  
  --enable-libfreetype \
  
  --enable-libtheora \
  
  --enable-libvorbis \
  
  --enable-libmp3lame \
  
  --enable-nonfree \
  
  --enable-gpl
  
  PATH="$HOME/bin:$PATH" make
  
  make install
  
  make distclean
  
  hash -r

• how to update ffmpeg password in Config.php

  15 décembre 2014, par Ray Martin Balilo

  I have successfully installed PHP FFMPEG on my laptop which is windows 8 (I was using xampp) following this guide

  http://myownhomeserver.com/2012/12/how-to-install-ffmpeg-php-php-5-4-on-windows-8-xampp-1-8-1/

  after installing it, the test file is working just right. Then after that i try the video conversion guide following this

  http://myownhomeserver.com/2012/12/how-to-run-execute-ffmpeg-with-php-on-windows-pc/

  my problem is that when i try to click the convert it button. It says that "The page at localhost:8080 says : Request failed !"

  according to the comment in the guide the solution is i need to update the password of ffmpeg in config.php

  this is the code of config.php :

  <?php
  
  /**
  
  * Configuration File 
  
  *
  
  * @ver     0.1
  
  */
  
  define('DS', DIRECTORY_SEPARATOR);
  
  
  
  define('BASE_PATH', realpath(dirname(__FILE__)) . DS);
  
  
  
  $_protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != "off") ? "https" : "http";
  
  
  
  define('BASE_URL', $_protocol ."://". $_SERVER['HTTP_HOST'] . dirname($_SERVER['SCRIPT_NAME'])      .'/');
  
  
  
  // Videos to convert path
  
  define('SOURCE_PATH', BASE_PATH . 'source'. DS);
  
  
  
  // Converted videos output path
  
  define('OUTPUT_PATH', BASE_PATH .'output'. DS);
  
  
  
  // Logs Path
  
  define('LOG_PATH', BASE_PATH .'logs'. DS);
  
  
  
  // POST URL for Javascript Queries
  
  define('POST_URL', BASE_URL .'process.php');
  
  
  
  // Execution Script URL (Where the ffmpeg command will be posted to)
  
  define('EXEC_URL', BASE_URL .'ffmpegExec.php');
  
  
  
  // FFMPEG Path (ffmpeg.exe)
  
  define('FFMPEG_PATH', BASE_PATH .'ffmpeg\bin\ffmpeg.exe');
  
  
  
  // FFMPEG Password (Change the value 't^$bG1c4=9u63yyKLmW7Q71tu17p5q' with something new!)
  
  define('FFMPEG_PW', sha1('sdfdfe'));
  
  
  
  if( !file_exists(SOURCE_PATH) )
  
      mkdir(SOURCE_PATH, 0755, true);
  
  
  
  if( !file_exists(OUTPUT_PATH) )
  
      mkdir(OUTPUT_PATH, 0755, true);
  
  
  
  if( !file_exists(LOG_PATH) )
  
     mkdir(LOG_PATH, 0755, true);

  My problem is I dont know how to locate the password of ffmpeg in my windows 8 laptop. Can someone tell me how can I locate the password of ffmpeg ?
  I know I need to make some minor changes in config.php, mainly setting the FFMPEG_PATH constant to the correct location for my Windows computer. But I dont know how... please someone help me please

  Thanks for the help in advance
