    live on ;
    meta copy;
    allow play all;

    pull rtmp://184.72.239.149/vod/BigBuckBunny_115k.mov name=test live=1;


    exec_push   /usr/bin/ffmpeg -re -i rtmp://localhost:1936/mypull/$name -vcodec libx264 -acodec libmp3lame -f flv rtmp://localhost:1936/hls/$name;


}


application dash {
        live on;
        dash on;

• Resize videos and keep codecs using PHP-FFMpeg

  30 décembre 2019, par tmp_hallenser

  I’m trying to resize a couple of videos (with different codecs) using PHP-FFMpeg. The official documentation gives the following example (see https://github.com/PHP-FFMpeg/PHP-FFMpeg)

  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open('video.mpg');
  
  $video
  
      ->filters()
  
      ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
      ->synchronize();
  
  $video
  
      ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
  
      ->save('frame.jpg');
  
  $video
  
      ->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4')
  
      ->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
  
      ->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');

  Since I don’t want to specify the codec (take the same as the source file), I was trying to create a copy-format and use this format instead for the save command.

  class MOVFormat extends FFMpeg\Format\Video\DefaultVideo
  
  {
  
      public function __construct($audioCodec = 'copy', $videoCodec = 'copy')
  
      {
  
          $this
  
              ->setAudioCodec($audioCodec)
  
              ->setVideoCodec($videoCodec);
  
      }
  
  
  
      public function supportBFrames()
  
      {
  
          return false;
  
      }
  
  
  
      public function getAvailableAudioCodecs()
  
      {
  
          return ['copy'];
  
      }
  
  
  
      public function getAvailableVideoCodecs()
  
      {
  
          return ['copy'];
  
      }
  
  }

  This results in Filtergraph '[in]scale=320:240 [out]' was defined for video output stream 0:0 but codec copy was selected. and Filtering and streamcopy cannot be used together.

  Technically, it should be possible to resize without specifying the codec if I look at this reply : https://superuser.com/a/624564

  Any help is appreciated !

• Matomo 2 reaches end of life soon (December 2017), update now !

  7 décembre 2017, par Matomo Core Team — Community

  In less than three weeks, Matomo (Piwik) 2 will be no longer supported. This means that no further (security) updates will be released for this version. As per our Long Term Support announcement, Matomo 2.X is supported for 12 months after the initial release of Matomo 3.0.0 which was on December 18th 2016. Therefore, Matomo 2 will no longer receive any updates after December 18th 2017.

  It has been almost a year since we released Matomo (Piwik) 3 and we highly recommend updating to Matomo 3 ASAP. The major new release came with a new UI, performance and security improvements. If you are still on Matomo 2, the security improvements alone should be worth updating your Matomo to Matomo 3 now. We cannot recommend this enough.

  The update to Matomo (Piwik) 3 should be smooth, but may take a while depending on the amount of data you have.

  • If you have any problem with the update, feel free to get in touch with us, or ask in the forums.
  • If you are currently using Matomo (Piwik) self-hosted and would like to be upgraded, plus your Matomo managed in the official Cloud-hosted service, contact InnoCraft Cloud and they will migrate your database.

  At Matomo (Piwik) and InnoCraft, the company of the makers of Matomo, we have seen many thousands of Matomo installations upgraded over the past year and look forward to an exciting future for Matomo 3 and beyond !
