• call ffmepg from apache php without full path

  14 février 2015, par ffmpeg fan

  I need a apache /php to recognize ffmpeg command without specifing the full bath of /usr/local/bin/ffmpeg

  calling ffmpeg from command line executes the program
  calling ffmpeg from php via web does not execute the program
  calling /usr/local/bin/ffmpeg from php via web does execute the program

  why :
  a php script calls youtube-dl (a compiled program) and executes ffmpeg internally

  thank you in advance -
  tried ffmpeg path :
  which ffmpeg
  /usr/local/bin/ffmpeg

  echo $PATH
  
  /usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
  
  
  
  
  
  #php code for testing:
  
  $output = shell_exec('/usr/local/bin/ffmpeg 2>&1');
  
  echo "shell exec /usr/local/bin/ffmpeg <pre>$output</pre>";
  
  #Response:
  
  ffmpeg version 2.5.3 Copyright #(good)
  
  
  
  #Second php code for testing:
  
  $output = shell_exec('ffmpeg 2>&amp;1');
  
  echo "shell exec <pre>$output</pre>";
  
  #Response:
  
  sh: ffmpeg: command not found #(bad)

• Why am I getting an exit status of 1 ?

  24 mai 2018, par Akaisteph7

  So, I am writing this code to analyze this video but I am facing this issue when I try to run it in Spyder, Anaconda :

  import subprocess
  
  from subprocess import call
  
  import math
  
  
  
  ##Converts the given file into a series of images
  
  def Video_to_Image_Converter(fileName):
  
      res1 = call("ffmpeg -i " + fileName + " -vf fps=1 frame-%d.jpg", shell=True)
  
      print(res1)
  
      result = subprocess.Popen('ffprobe -i '+ fileName +' -show_entries format=duration -v quiet -of csv="p=0"', stdout=subprocess.PIPE,stderr=subprocess.STDOUT, shell=True)
  
      output = result.communicate()
  
      print(output)
  
      #return math.ceil(float(output[0])) + 1
  
  
  
  
  
  if __name__ == '__main__':
  
      videoLength = Video_to_Image_Converter('sampleVideo.wmv')
  
      print(videoLength)

  So, this code worked fine in iPython but I started having issues when trying to use Spyder. res1 should have an exit status of 0 if everything went well but it is 1. However, I do not know what went wrong. All it says when running subprocess.check_output on call is :

  Command 'ffmpeg -i sampleVideo.wmv -vf fps=1 frame-%d.jpg' returned non-zero exit status 1

  Please help.

• Can't download Accord NuGet in VS 2015 nor VS 2017

  26 juin 2017, par John Leone

  Here is the package,,, NuGet Accord.Video.FFMPEG

  Here is the error,,,
  Package restore failed. Rolling back package changes for ’EssentialTimeLapseVideo’.

  I used this NuGet in a Windows Form app I am working on, and had no issues. Then something came up with Time Lapse, and I wanted to use it in a UWP, but, for some reason it won’t install.

  I tried the mirror suggested, and got the following.
  

  Any help would be appreciated. Thanks, John.
