• Laravel FFMPEG Add HLS Video Watermark issue

  6 juin 2020, par Jefriiyer S

  I'm using "pbmedia/laravel-ffmpeg" : "^7.0" in "laravel/framework" : "^7.0" , I want to add water mark to the HLS video, Here is the example given in the github repo https://github.com/pascalbaljetmedia/laravel-ffmpeg

  



  FFMpeg::open(['video.mp4', 'video2.mp4'])
    ->export()
    ->addFilter(function(ComplexFilters $filters) {
        // $filters->watermark(...);
    });


  



  But It's not have enough information, Here is the working example everyware in the internet

  



  addFilter(function ($filters) {
            $filters->watermark($watermarkPath, [
                'position' => 'relative',
                'bottom' => 50,
                'right' => 50,
            ]);
        })


  



  But the watermark method has 2 more required parameters in the library

  



  addFilter(function (ComplexFilters $filters) {
            $filters->watermark($in,$watermarkPath,$out, [
                'position' => 'relative',
                'bottom' => 50,
                'right' => 50,
            ]);
        })


  



  What should I pass for $in and $out
Here is the full code which I have

  



  $low = (new X264('aac'))->setKiloBitrate(100);
$mid = (new X264('aac'))->setKiloBitrate(250);
$high = (new X264('aac'))->setKiloBitrate(500);


       FFMpeg::fromDisk('local')
        ->open($this->video->path)
        ->exportForHLS()
        ->addFilter(function (ComplexFilters $filters) {
            $filters->watermark(null,public_path('watermark.png'),null, [
                'position' => 'relative',
                'bottom' => 50,
                'right' => 50,
            ]);
        })
        ->addFormat($low)
        ->addFormat($mid)
        ->addFormat($high)
        ->save("public/videos/{$this->video->id}/{$this->video->id}.m3u8");


  



  By passing null I can't able to see any watermark , If I remove those nulls , I'll have error

  



  

  



  Please look at the required parameters in watermark function under ComplexFilters,
Thanks :).

  


• avcodec/ffv1enc : mark RGB48 support as non-experimental

  5 janvier 2018, par Jérôme Martinez

  avcodec/ffv1enc : mark RGB48 support as non-experimental
  Resulting bitstream was tested with a conformance checker
  
  using the last draft of FFV1 specifications.
  Signed-off-by : Michael Niedermayer <michael@niedermayer.cc>
  Also the files are already in the wild, and decoder support is
  
  thus needed. And with decoders widely supporting it, there is no
  
  advantage in not allowing it in the encoder.
  
  The exact bitstream format may change in future versions of the
  
  spec, if improvments are found.
