• Using HW accelerate video encoding

  9 juin 2019, par RoboGil

  I am trying to get ffmpeg HW acceleration on an UpBoard .
  It uses an Atom x5 z8350 processor and Intel HD 400 GPU

  I have also followed this tutorial in order to compile ffmpeg with libmfx enabled.

  $ ffmpeg -encoders | grep qsv

• av_format/hlsenc : fix %v handling by format_name function

  av_format/hlsenc : fix %v handling by format_name function
  Hi All,
  When multiple variant streams are specified by var_stream_map option, %v
  
  placeholder in various names ensures that each variant has its unique
  
  names. Most of %v handlng is done in format_name function. Currently
  
  in this function the result buffer is the same as the
  
  input pattern buffer, so you must allocate it before calling format_name
  
  function. It also means, that it is silently assumed that the result
  
  string will NOT be
  
  longer that the pattern string. It is true most of the time, because %v
  
  may appear only once in the pattern string and number of variant streams
  
  is less than 100 in practical cases. But theoretically it will fail if
  
  specified number of variant streams is greater than 100 (i.e. longer
  
  than 2 digits).
  
  This patch fixes this behaviour by altering format_name function to
  
  allocate the
  
  result buffer and return it to the caller.
  Please, review this patch.
  best,
  Bela

• array_merge() : Argument #2 is not an array after adding class into providers

  19 juin 2019, par Daman Mokha

  I am using pbmedia/laravel-ffmpeg as soon as I installed and added the providers and alias, it shows me the following error. This code was simply working on another machine

  array_merge(): Argument #2 is not an array

  I have tried the following things

  1. Composer update/ and Fresh install
  2. Cleaning the bootstrap/cache/
  3. Checked the config file for laravel-ffmpeg it’s there and fine
  4. Publish the config file using the artisan CLI tool : php artisan vendor:publish —provider="Pbmedia\LaravelFFMpeg\FFMpegServiceProvider"

  Here is the portion from laravel.log when I tried to run.

  [2019-06-19 00:34:40] local.ERROR: ErrorException: array_merge(): Argument #2 is not an array in /Users/damanmokha/edetyv2/vendor/laravel/framework/src/Illuminate/Support/ServiceProvider.php:59

  #11 {main} 

  if I don’t add these providers it works fine, but then I am not able to use ffmpeg without that.
