• Android, AOSP tree, external project (ffmpeg) is built for AMD64

  22 avril 2015, par kagali-san

  I’m trying to build ffmpeg4android on current AOSP tree (from /external), which is lunch-configured to aosp_arm-eng and set to PLATFORM_VERSION=4.2.

  Resulting files are generated for AMD64 (host native) architecture, even though the major rest of tree is built (as expected) ARM :

  readelf -a android/aosp_arm-eng/ffplay|egrep "Class :|Machine :"
  Class : ELF64 Machine :
  Advanced Micro Devices X86-64

  versus

  readelf -a
  aosp/out/target/product/generic/symbols/system/lib/libril.so | egrep "Class :|Machine :"

  Class : ELF32
  Machine : ARM

  ---

  I will probably switch to other ways of getting ffmpeg-arm (presumably the one described here) ; the reason of asking this question is to understand, at which build stage does cross-compilation environment breaks.

• error in ffmpeg when sending image from pipe via php

  12 décembre 2013, par Abdul Ali

  used the following tutorial to send an uploaded image to ffmpeg from php via pipe.

  Image pipe from php to ffmpeg

  however it raises an eror saying that the pipe has invalid data in it.

  pipe:: Invalid data found when processing input

  following is the php code for uploading an image file

  $tempPath = $_FILES['vdofile']['tmp_name'];
  
  
  
  print_r($tempPath);
  
  
  
  $descriptorspec = array(
  
      0 => array("pipe", "r"), // stdin is a pipe that the child will read from
  
      1 => array("pipe", "w"), // stdout is a pipe that the child will write to
  
      2 => array("file", "error-output.txt", "a") // stderr is a file to write to
  
      );
  
  
  
  $img = imagecreatefromjpeg($tempPath);
  
  
  
   $proc = proc_open("ffmpeg image2pipe -i - -y image.jpg", $descriptorspec, $pipes);
  
  
  
   if (is_resource($proc)) {     
  
       /*
  
        * $pipes[0] = write something to command being run
  
        * $pipes[1] = read something from command
  
        * $pipes[2] = error from command 
  
        */
  
         fwrite($pipes[0], $_FILES['vdofile']['tmp_name']);
  
         fclose($pipes[0]);
  
   }
  
   proc_close($proc);
  
  ?>

  and simple html uploading code is as follows :

   <form action="upload.php" method="post" enctype="multipart/form-data">
  
          <input type="file" />
  
  
  
          <input type="submit" value="Upload" />
  
      </form>

  the error file generated is as follows :

  any assistance will be appreciated.

  the code still produces an error :
