• How do I set up FFmpeg on Laravel Forge ?

  31 juillet 2022, par James Stewart

  I have FFMPEG locally on my computer. It is working exactly as I need it to.

  


  I want to use it in production. I deploy a Laravel 8/Vue application to AWS via Laravel Forge. I am using the laravel-ffmpeg package for FFMPEG.

  


  I can't find any articles online and how to install FFMPEG on my server when using Laravel forge. I have added two binaries (ffmpeg [320kb], ffprobe [280kb]) to my project and I have used the suggested laravel-ffmpeg.php config file from that project's docs :

  


  return [
    'ffmpeg' => [
        'binaries' => env('FFMPEG_BINARIES', 'usr/bin/ffmpeg'),
        'threads' => 12,   // set to false to disable the default 'threads' filter
    ],
    'ffprobe' => [
        'binaries' => env('FFPROBE_BINARIES', 'usr/bin/ffprobe'),
    ],
    'timeout' => 3600,
    'log_channel' => env('LOG_CHANNEL', 'stack'),   // set to false to completely disable logging
    'temporary_files_root' => env('FFMPEG_TEMPORARY_FILES_ROOT', sys_get_temp_dir()),
    'temporary_files_encrypted_hls' => env('FFMPEG_TEMPORARY_ENCRYPTED_HLS', env('FFMPEG_TEMPORARY_FILES_ROOT', sys_get_temp_dir())),
];


  


  I've tried moving the binaries around (so not in usr/bin etc) but it doesn't seem to make a difference. I get errors like this :

  


  Alchemy\BinaryDriver\Exception\ExecutionFailureException: ffprobe failed to execute command 'ffprobe' '-help' '-loglevel' 'quiet':

Error Output:

 sh: 1: exec: ffprobe: not found


  


  Is there some 100% certain way to actually get ffmpeg up and running in Forge ? Am I missing something real obvious ?

  


• Using ffmpeg native aac codec, but metadata says libvo_aacenc, and faststart not supported ?

  8 juillet 2016, par Bob S

  I’m using ffmpeg and am trying to switch from using the ’libvo_aacenc’ encoder to the native aac encoder. It seems to work, but the metadata in the output seems to indicate that it’s still using the old encoder.

  I changed the audio portion of my ffmpeg call from

  -i out.wav -acodec libvo_aacenc

  to

  -i out.wav -acodec aac -strict experimental

  But the output includes this :

  Metadata :

  encoder         : Lavf53.21.1
  
  
  
  Stream #0.0: Video: libx264, yuv420p, 432x256, q=-1--1, 30 tbn, 30 tbc
  
  
  
  Stream #0.1: Audio: libvo_aacenc, 44100 Hz, 1 channels, s16, 200 kb/s

  I don’t understand where it is still getting the ’libvo_aacenc’ from ?

  Another problem, maybe unrelated, is that when I try to add the "-movflags +faststart" option to my call, I get errors :

  [mp4 muxer @ 0x49ad520] [Eval @ 0x3e59d37c6b0] Undefined constant or missing ’(’ in ’faststart’
  [mp4 muxer @ 0x49ad520] Unable to parse option value "faststart"
  [mp4 muxer @ 0x49ad520] Error setting option movflags to value +faststart.

  From looking online it would appear my ffmpeg version is old, pre faststart, but my ffmpeg version is 0.8.17-4:0.8.17-0ubuntu0.12.04.1, Copyright (c) 2000-2014 the Libav developers built on Mar 16 2015 13:26:50 with gcc 4.6.3

  That seems like it should include faststart, which was introduced in 2013, right ?
  Any ideas what could be going on ?

  Thanks very much,

  Bob
