• FFMpeg PHP : Unable to load FFProbe

  23 septembre 2023, par Artem Konyaev

  I am using the Lumen PHP framework which is the form of Laravel. On the server side I have Bitnami.

  


  I get the 500 error when the code that uses FFMpeg is being executed. My part of the code which leads to the problem :

  


  $ffmpeg = FFMpeg::create([
            'ffmpeg.binaries'   => '/opt/bitnami/apache/htdocs/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg',
            'ffprobe.binaries'  => '/opt/bitnami/apache/htdocs/vendor/php-ffmpeg/php-ffmpeg/src/FFProbe',
            'timeout' => 0
]);


  


  I also tried it without 'timeout'.

  


  Here are the details of the error that I get in the server response :

  


  


  [ExecutableNotFoundException](#trace-box-2) [ExecutableNotFoundException](#trace-box-1)

  


  HTTP 500 Internal Server Error

  


  Unable to load FFProbe

  


  Exceptions 2

  


  FFMpeg\Exception\ExecutableNotFoundException

  


  in /opt/bitnami/apache/htdocs/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg/Driver/FFProbeDriver.php (line 50)

  


  


  45.         $binaries = $configuration->get('ffprobe.binaries', ['avprobe', 'ffprobe']);

      


  


  46.         

      


  


  47.         try {

      


  


  48.             return static::load($binaries, $logger, $configuration);

      


  


  49.         } catch (BinaryDriverExecutableNotFound $e) {

      


  


  50.             throw new ExecutableNotFoundException('Unable to load FFProbe', $e->getCode(), $e);

      


  


  51.         }

      


  


  52.     }

      


  


  53. }

      


  


  


  


  I tried changing the project folder rights by sudo chmod -R 777 /opt/bitnami/apache/htdocs. Not sure if it worked. Here is the current state :

  


  


  $ ls -l /opt/bitnami/apache/htdocs

  Tried adding this to my .env file in /opt/bitnami/apache/htdocs :

FFPROBE_BINARIES=/opt/bitnami/apache/htdocs/vendor/php-ffmpeg/php-ffmpeg/src/FFProbe


  


  


• C program cannot find function which included in header file

  17 juin 2013, par Juneyoung Oh

  I made program like this.

    1 #include 
  
    2 #include 
  
    3 #include 
  
    4 #include "libavformat/avformat.h"
  
    5 
  
    6 int main (int argc, char* argv[]){
  
    7         av_register_all();
  
    8         return 0;
  
    9 }

  My header file located in

  root@ubuntu:/home/juneyoungoh/getDuration# find / -name "avformat.h"
  
  /root/ffmpeg/libavformat/avformat.h
  
  /usr/local/include/libavformat/avformat.h

  then I run with gcc getDuration.c , but I show message like below.

  root@ubuntu:/home/juneyoungoh/getDuration# gcc getDuration.c 
  
  /tmp/ccwjonqH.o: In function `main':
  
  getDuration.c:(.text+0x10): undefined reference to `av_register_all'
  
  collect2: ld returned 1 exit status

  Frankly, I do not have any idea what makes this.

  Thanks for your answers.

  ========================== edited #1 ===========================

  when I "ls /usr/local/lib", I get this.

  root@ubuntu:/home/juneyoungoh/getDuration# ls /usr/local/lib/
  
  libavcodec.a   libavutil.a    libopus.la       libvpx.a   python2.7
  
  libavdevice.a  libfdk-aac.a   libpostproc.a    libx264.a
  
  libavfilter.a  libfdk-aac.la  libswresample.a  libyasm.a
  
  libavformat.a  libopus.a      libswscale.a     pkgconfig

  you can see libavformat.a in the very first of the last line.

  so if I command like what you suggest, I get below.

  /root/ffmpeg/libavformat/vqf.c:244: undefined reference to `av_free_packet'
  
  /usr/local/lib//libavformat.a(vqf.o): In function `add_metadata':

  /usr/local/lib//libavformat.a(wavenc.o): In function `wav_write_packet':
  
  /root/ffmpeg/libavformat/wavenc.c:181: undefined reference to `av_log'

  It is too long, so I just post little part of that.

  I think all link of libavformat has been broken, But I do not know

  what can I do to fix that link.

  I have installed that their official link said.
