• Get thumbnail image from video not working with PHP and ffmpeg (Ubuntu)

  16 octobre 2015, par a_pajic

  I have generated a $cmd string :

  ffmpeg -i /home/alen/www/mysite/video/Guitarist-139.mp4 -an -ss 0 -s
  1280x720 /home/alen/www/mysite/img/Guitarist-139.jpg

  then I have typing a command in PHP :

  shell_exec($cmd) ;

  but not working,

  then I have pasted this string in terminal but in terminal work perfectly.

  What is wrong.

• Code forks fine on macbook laptop..but on Imac(Yosemite) I get errors in my shell script

  2 mars 2015, par arantx

  I’m still figuring out how to work within the terminal, mainly with FFmpeg at the moment. I have this code running for a while now on my macbook pro (snow leopard I think). It works fine, no glitches whatsover. I just got an Imac (yosemite) and I wanted to install the same code, but now it gives these minor stupid syntax errors - that are not at fault on my laptop ! Its seems bizar to me, but maybe it’s something I forgot to install .. like a certain library ? I’ve tried to use the same steps as before but ofcourse I might have forgotten about one..

  The code will make a clip of 5 seconds on every hour via the embedded webcam, (the hourly notice is being programmed within crontab). This is the shell script :

  ---

  #!/bin/bash
  
  
  
  FNAME=videocapture_`date +"%F_%H_%M"`.mpg
  
  echo $FNAME
  
  
  
  /usr/local/bin/ffmpeg -t 5 -f avfoundation -i "default" $FNAME

  ---

  And these are the erros (I tried to change a few small syntaxes to see if it would stop but it just finds new errors)

  "SyntaxError: EOL while scanning string literal
  
  Arantxas-iMac:~ arantx$ python /Users/arantx/Documents/terminal\ stuff/camera.sh 
  
    File "/Users/arantx/Documents/terminal stuff/camera.sh", line 3
  
      FNAME=videocapture_'date +"%F_%H_%M"`.mpeg
  
                                               ^
  
  SyntaxError: EOL while scanning string literal
  
  Arantxas-iMac:~ arantx$ python /Users/arantx/Documents/terminal\ stuff/camera.sh 
  
    File "/Users/arantx/Documents/terminal stuff/camera.sh", line 3
  
      FNAME=videocapture_'date +"%F_%H_%M"`.mpeg 
  
                                                ^
  
  SyntaxError: EOL while scanning string literal
  
  Arantxas-iMac:~ arantx$ python /Users/arantx/Documents/terminal\ stuff/camera.sh 
  
    File "/Users/arantx/Documents/terminal stuff/camera.sh", line 3
  
      FNAME=videocapture_'date +"%F_%H_%M"`.mp4"

  If someone can point something out that I might have missed, let me know !

  Kind regards,

• PHP ffmpeg not found

  17 décembre 2020, par heisenberg

  so I already browse all the forum but I still get error "sh : 1 : /usr/bin/ffmpeg : not found".
If I run ffmpeg from terminal it works just fine and can do convert video without problem, but if I use PHP exec or shell_exec, the return always ffmpeg not found.

  


  this is my code :

  


  $cmd = "/usr/bin/ffmpeg";

$run = exec($cmd." -i 'linkvideo.m3u8' -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 /test_stream/newfile.mp4 2>&1");

var_dump($run);


  


  if I run which ffmpeg or whereis ffmpeg from terminal it will return /usr/bin/ffmpeg, but if I exec('which ffmpeg') from my code it will return ffmpeg not found. I already chown and chmod the ffmpeg to grant rwx, i tried move ffmpeg to /usr/local/bin still same result. If i run whoami from terminal it will show root but if from my code using exec('whoami') it will show www-data so maybe I miss something about the user but I also already tried to chown ffmpeg from root to www-data still the result is ffmpeg not found, maybe anyone can help, I'm using codeigniter and already install ffmpeg in server using sudo apt-get ffmpeg, thanks before !
