• Whatsapp FFMPEG thumbnail is not showing

  7 avril 2020, par Youssof H.

  I want to run a command that will add an image as a thumbnail to a video. The video will be shared by WhatsApp with a thumbnail showing up.

  



  The problem is that after running the following command thumbnails don't show up in Whatsapp though it shows on Windows 10.

  



  ffmpeg -i path/to/Video.mp4 -i path/to/Video.png -map 0 -map 1 -c copy -c:v:1 png -disposition:v:1 attached_pic -strict -2 path/to/out.mp4


  



  And another problem is that the video with a thumbnail doesn't play on Android, iPhone, Windows, nor on Linux.

  What am I doing wrong ?

  



  Note : It's okay if it works with python.

  


• I have installed FFMPEG and can't find it inside a PHP script

  14 novembre 2019, par Antop

  I have installed FFMPeg in CentOS. It works perfectly.
  It’s inside /usr/bin directory. Also, I have PHP 7.2.24 that comes with Plesk 18.0.20.

  I want to use FFMPeg inside a PHP script, but that script can’t find the executable of FFMpeg. I have tried giving the exact route (/usr/bin/ffmpeg) but doesn’t work.

  It’s a production server. The same script, in my development server (macOS) works perfectly.

  I tried using :

  var_dump(getenv('PATH'));
  
  var_dump(exec('which ffmpeg'));
  
  var_dump(ini_get('open_basedir'));
  
  var_dump(is_file(exec('which ffmpeg')));
  
  var_dump(is_executable(exec('which ffmpeg')));

  And it returns me :

  string(49) "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin"
  
  string(0) ""
  
  string(44) "/var/www/vhosts/name-of-the-domain.com/:/tmp/"
  
  bool(false)
  
  bool(false)
  
  NULL

  ¿What could be happening ?

  A very strange thing I’ve noticed is that I can’t access any command via php :
  I tried using it with echo

  var_dump(exec('which echo'));
  
  var_dump(is_file(exec('which echo')));
  
  var_dump(is_executable(exec('which echo')));

  And it returns me :

  string(0) ""
  
  bool(false)
  
  bool(false)
  
  NULL

  And the permissions are right :

  [root@vps bin]# ls -lha echo
  
  -rwxr-xr-x 1 root root 33K ago 20 08:25 echo
  
  
  
  [root@vps bin]# ls -lha ffmpeg
  
  -rwxr-xr-x 1 root root 217K abr  4  2019 ffmpeg

  But if I make a

  var_dump(exec('echo "HELLO"'))

  it returns me

  string(5) "HELLO"

• More problems with FFmpeg not recognizing the directory I'm sending it to

  8 novembre 2019, par Requiem_7

  I am creating a program that takes an audio file, breaks it up into 30-second audio files, and sends those files to Google’s Speech Recognition API to transcribe the audio. I’m using FFmpeg to break up the original audio file and make the 30-second files. It was working for about 20 minutes and I didn’t change anything but now it’s giving me an error saying that no such file or directory exists.

  Here is the error it gives me :

  Both the folder "source" with "valve.flac" exists as well as the folder "parts" and the files "out0.flac", etc. I was originally trying in the wav file format, switched to flac and it worked for about 20 minutes then stopped working.
