• Passing arguments to Powershells Call Operatore - I can't get it to work

  2 janvier 2020, par morgola22

  For some reason I cannot get even the most simple Ffmpeg case to work :

  $pathToFfmpeg = "PathToFfmpeg\ffmpeg.exe"
  
  $video = "PathToVideoFile\video.mp4"
  
  $param = "--i $video", "output.avi"
  
  $execute = &$pathToFfmpeg $param

  This should result in the most basic Ffmpeg usage according to Ffmpeg website : ffmpeg -i input.mp4 output.avi.
  However all I receive is :

  ffmpeg.exe : ffmpeg version git-2020-01-01-7b58702 Copyright (c) 2000-2020 the FFmpeg developers

  So it seems I am doing something wrong. Anybody knows how I get this to work ? I have tried different methods to create the params array and checked with EchoArgs.exe, but no avail. I am out of ideas. It looks like Ffmpeg does not recognise what Powershell is passing to it.

• Evolution #4350 (En cours) : Faire l’ajout de la config mini dans le paquet.xml d’ecrire

  24 septembre 2019, par b b

  Pour revenir sur la proposition d’augmenter à PHP 5.6 mini je pense qu’on peut le faire sans problème. Pour info, on nécessitait PHP 5.4 mini pour raison de compat avec debian 7, cf r23619 => "On nécessite PHP 5.4 minimum. Note : Debian 7 Wheezy est supportée avec PHP 5.4 jusque fin mai 2018…"

  À ce jour, la version mini de PHP sous debian est la 5.6 proposée par debian 8 qui est supportée jusqu’au 30 juin 2020, ref https://wiki.debian.org/fr/LTS & https://packages.debian.org/fr/jessie/php5

• (osx) ffmpeg combining mp3 and png to mp4 resulting in mp4 with no audio

  18 juin 2016, par Ian H

  I’m writing a python script that uses unix commands to do some file conversions/renderings. I’m trying to join some mp3 files with png files to get mp4s that are the picture with the mp3 playing over them. However, I’ve tried this with lots of different codecs and settings, and the output mp4 video never seems to have audio in it. I’ve looked at any answer to any question even related to ffmpeg and haven’t found a solution.

  Some commands I’m trying to get working currently :

  ffmpeg -loop 1 -i slide_shot%d.png -i %s -c:v libx264 -pix_fmt yuv420p 
  
  -s 720x540 -t %.3f -c:a aac -b:a 192k -shortest out%d.mp4" 
  
  % (i, aud, slideTime, i)
  
  
  
  ffmpeg -loop 1 -i slide_shot%d.png -i %s -shortest -t %.3f -write_xing 
  
  0 -c:v libx264 -c:a libmp3lame -pix_fmt yuv420p -tune stillimage out%d.mp4" 
  
  % (i, aud, slideTime, i)
  
  
  
  ffmpeg -loop 1 -i slide_shot%d.png -i %s -shortest -t %.3f -write_xing 
  
  0 -c:v libx264 -c:a copy -pix_fmt yuv420p -tune stillimage out%d.mp4" 
  
  % (i, aud, slideTime, i)

  I’m currently using the third one. However, none of them are giving me any audio. For reference, i is a loop iterator for naming consistency, aud is the audio filepath, and slideTime is the number of seconds the video should take.

  Using this command, I’m currently getting this output in the Terminal :

  Has anyone ran into a similar problem, and if so, how did you go about fixing it ? Thanks in advance for looking at my question.
