  mmaldec : hack against buffering problems on broken input
  I can’t come up with a nice way to handle this. It’s hard to keep the
  
  lock-stepped input/output in this case. You can’t predict whether the
  
  MMAL decoder will output a picture (because it’s asynchronous), so
  
  you have to assume in general that any packet could produce 0 or 1
  
  frames. You can’t continue to write input packets to the decoder,
  
  because then you might get too many output frames, which you can’t
  
  get rid of because the lavc decoding API does not allow the decoder
  
  to return an output frame without consuming an input frame (except
  
  when flushing).
  The ideal fix is a M:N decoding API (preferably asynchronous), which
  
  would make this code potentially much cleaner. For now, this hack
  
  will do.

• Unable to load FFProbe driver for FFmpeg

  4 février 2016, par Kapil Ropalekar

  Hi i am trying to install php-ffmpeg.
  Can someone guide me or correct me in my steps.

  1. I installed the composer on windows and then traversed to my folder i had created to run install ffmpeg cmd

  2. After running this command a composer.json, composer.lock file were created along with a vendor folder.

  3. Later installed the Shared FFMpeg build for 64bit from here

     http://ffmpeg.zeranoe.com/builds/

  and form this folder copied the bin folder to my directory to set the ffmpeg and ffprobe path during create() like this

  $ffmpeg = \FFMpeg\FFMpeg::create([
  
      'ffmpeg.binaries'  => '/vendor/bin/ffmpeg.exe',
  
      'ffprobe.binaries' => '/vendor/bin/ffprobe.exe' 
  
  ]);

  Currently i am getting this error which says :

  "Fatal error: Uncaught exception 'Alchemy\BinaryDriver\Exception\ExecutableNotFoundException' with message 'Executable not found, proposed : /vendor/bin/' in D:\xampp\htdocs\health\vendor\alchemy\binary-driver\src\Alchemy\BinaryDriver\AbstractBinary.php:160 Stack trace: #0 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php(48): Alchemy\BinaryDriver\AbstractBinary::load('/vendor/bin/', NULL, Object(Alchemy\BinaryDriver\Configuration)) #1 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe.php(207): FFMpeg\Driver\FFProbeDriver::create(Array, NULL) #2 D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFMpeg.php(117): FFMpeg\FFProbe::create(Array, NULL, NULL) #3 D:\xampp\htdocs\health\ff.php(6): FFMpeg\FFMpeg::create(Array) #4 {main} Next exception 'FFMpeg\Exception\ExecutableNotFoundException' with message 'Unable to load FFProbe' in D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php:50 Stack trace: #0 D:\xampp\htdocs\he in D:\xampp\htdocs\health\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Driver\FFProbeDriver.php on line 50".

  So what could i have done wrong or am i missing any steps. Can someone point me to the right direction.
