• Need help to compile FFmpeg with MSVC tools

  30 janvier 2018, par Antwane

  I need to compile FFmpeg on Windows 10 using MSVC 2017 compiler. I followed some guides from :

  • https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC
  • https://www.ffmpeg.org/platform.html#Microsoft-Visual-C_002b_002b-or-Intel-C_002b_002b-Compiler-for-Windows
  • https://pracucci.com/compile-ffmpeg-on-windows-with-visual-studio-compiler.html

  I installed current stable version of MSYS, fixed link.exe and use of PATH environment, installed make diffutils gcc pkg-config and downloaded c99-to-c89, nasm, and inttypes.h

  I think my environment is now correctly set up, I ran MSYS shell from MSVC Command prompt and have everything reachable.

  $ which cl
  
  /c/Program Files (x86)/Microsoft Visual Studio/2017/Professional/VC/Tools/MSVC/14.12.25827/bin/HostX64/x64/cl
  
  
  
  $ which link
  
  /c/Program Files (x86)/Microsoft Visual Studio/2017/Professional/VC/Tools/MSVC/14.12.25827/bin/HostX64/x64/link
  
  
  
  $ which yasm
  
  /home/Antoine/bin/yasm
  
  
  
  $ which c99conv
  
  /home/Antoine/bin/c99conv
  
  
  
  $ which c99wrap

  make: *** Aucune règle pour fabriquer la cible « ffbuild/library.mak ». Arrêt.

  Sorry for the french wording, I don’t know how to tell MSVC print its output in english. Basically, the error means :

  Makefile:47: target « qt-faststart » doesn't match the target pattern
  
  make: *** No rule to make target « ffbuild/library.mak ». Stopped.

  Side notes :

  $ tree ffbuild
  
  ffbuild
  
  ├── config.fate
  
  ├── config.log
  
  ├── config.mak
  
  └── config.sh

  That’s right, library.mak were not generated into ffbuild, but I don’t know why, and configure script didn’t output any error message...

  Does anybody can help me to find out what am I doing wrong ?

  Edit :

  make distclean doesn’t help

  $ make distclean

• FFMPEG PHP enter command lines ?

  3 mai 2019, par Robert

  You will have to excuse me I have been spending the past 2 days reading through old FFMPEG posts for an answer but did little but confuse myself.
  It seems from what I read FFMPEG-PHP wrappers aren’t supported anymore ??? and to be honest they don’t seem like the proper way of learning how to incorporate it with PHP as there is a whole lot more help for command line FFMPEG usage and the FFMPEG-PHP wrapper usage looks nothing like the command line as far as I can tell.

  So I have 2 questions on using ffmpeg with PHP. So we are on the same page I posted a little info below.

  I downloaded FFMPEG static for windows 64bit.
  I then ran (in composer)

        $ composer require php-ffmpeg/php-ffmpeg

  in my vendor folder i have the following path.

      vendor\ffmpeg-20190429-ac551c5-win64-static\bin

  if I open the command prompt in that folder and type FFMPEG I get.

   usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

  So I’m pretty sure FFMPEG is installed which was my goal.

  Now on my PHP side here is where I am at, and I’m not sure how this works.

  1ST QUESTION. Do I need to save my $_POST files to the drive before manipulating them ? Or can I use the $file and $filep as is ? I don’t really want to store those files, only the output.

  My SLIM code.

   $app->post('/telestrator', function(Request $request, Response $response) 
  
   {
  
  
  
   $response = array();
  
  
  
   if (isset ($_POST['ID']) && ($_POST['position']) && $_FILES['video'] 
  
   ['error'] === UPLOAD_ERR_OK && $_FILES['image']['error'] === 
  
   UPLOAD_ERR_OK) {
  
  
  
   $file = $_FILES['video']['tmp_name'];
  
   $filep = $_FILES['image']['tmp_name'];
  
   $time = $_POST['position'];
  
   $position = msToTime($time);
  
   $filetime = round(microtime(true) * 1000);
  
   $outputfolder = 'teletemp/';
  
  
  
   $ID = $_POST['ID'];
  
  
  
   $tempvid = $ID . 'tempvid' . 'mp4';
  
   $finalvid = $ID  . $filetime . 'mp4';
  
  
  
  
  
   $ffmpegpath = "public/ffmpeg.exe";
  
  
  
  echo "Starting ffmpeg...\n\n";
  
  echo shell_exec("$ffmpegpath -loop 1 -i $filep -c:v libx264 -t 3 -pix_fmt 
  
  yuv420p \"$outputfolder.\" $tempvid /");
  
   echo shell_exec("$ffmpegpath -i $file -t $position -c copy 
  
  \"$outputfolder\" 
  
   small-1.mp4 -ss $position -codec copy \"$outputfolder\" small-2.mp4 ");
  
   echo shell_exec("$ffmpegpath -i small-1.mp4 -i $tempvid.mp4 -i small- 
  
  2.mp4 \ 
  
   -filter_complex \"[0:v:0][1:v:0][2:v:0]concat=n=3:v=1:a=1[outv]\" \ 
  
   -map \"[outv]\" $finalvid" );
  
   echo "Done.\n";
  
  
  
   $upload = new videouploads();
  
  
  
          $desc = 'telestrated video for ' . $ID . $filetime;
  
          $ID = $_POST['ID'];  
  
  
  
          if ($upload->saveVideoFile($finalvid, getFileExtension($finalvid), 
  
   $desc, $ID)) {
  
              $response['error'] = false;
  
              $response['message'] = 'File Uploaded Successfullly';
  
          }
  
       else {
  
          $response['error'] = true;
  
          $response['message'] = 'Required parameters are not available';
  
      }
  
      echo json_encode($response);
  
    } 
  
   });
  
  
  
   function getFileExtension($file)
  
   {
  
   $path_parts = pathinfo($file);
  
   return $path_parts['extension'];
  
   }
  
  
  
   function msToTime($duration) {
  
   $seconds = floor($duration / 1000);
  
   $minutes = floor($seconds / 60);
  
   $hours = floor($minutes / 60);
  
   $milliseconds = $duration % 1000;
  
   $seconds = $seconds % 60;
  
   $minutes = $minutes % 60;
  
  
  
   $format = '%02u:%02u:%02u.%03u';
  
   $time = sprintf($format, $hours, $minutes, $seconds, $milliseconds);
  
   return rtrim($time, '0');
  
  
  
   }

  so it’s not running here is my postman. How do I get it to actually run the FFMPEG.

   Starting ffmpeg...
  
  
  
   Done.

• Android- Error during executing Runtime.getRuntime().exec() - Environment Null -ffmpeg

  18 février 2015, par Chaitanya Chandurkar

  I have compiled ffmpeg library on ubuntu 11.10 and ported compiled files on android.
  After compiling i got libffmpeg.so successfully. It gets loaded on android successfully.

  I am doing it on ubuntu 11.10 eclipse android emulator.

  I have created a small test application which act as command prompt which accepts command from user and displays result. (testing ffmpeg commands)

  When i run simple commands like "ls", "ls -l" it works perfectly. but when i simply type "cd mnt" or "ffmpeg" as command and try to run it. I got Warnings in Logcat saying that

  }

  I even tried process = pb.command(com).redirectErrorStream(true).start(); for execution. It gives me same error but this time environment was [ANDROID_SOCKET_Zygot] bla bla bla..

  EDIT 1 :
  I use Openjdk on ubuntu

  Help me out !!
