  avformat/movenc : remove the write_clli mov flag
  The clli atom is expected to be standardized soon. See
  
  http://ffmpeg.org/pipermail/ffmpeg-devel/2020-April/259529.html
  We now write the clli atom by default.

  avformat/movenc : write the mdcv atom by default
  The mdcv atom isn't in ISO/IEC 14496-12:2015 but it is expected to be
  
  added soon. See :
  
  http://ffmpeg.org/pipermail/ffmpeg-devel/2020-April/259529.html
  The mdcv atom is already parsed in FFmpeg in mov.c.

• React Electron ffmpeg-extract-frames build error

  28 mars 2020, par taylorallen0913

  I am using the npm module ffmpeg-extract-frames for splitting video frames. It works completely fine when I am testing the module in a vanilla node environment. However, when I import the module in my Electron React desktop app component, it gives me a error when building.

  This is how I am importing it :

  const extractFrames = require("ffmpeg-extract-frames");

  This is the error I am getting when building in my React Electron component :

  > expedition-hacks-project@0.1.0 build /home/taylorallen/Desktop/expedition-hacks-project
  
  > set "FLUENTFFMPEG_COV=false" && react-scripts build

  I found a github issue https://github.com/fluent-ffmpeg/node-fluent-ffmpeg/issues/573#issuecomment-305408048 addressing this error, and I set FLUENTFFMPEG_COV=0 on in my build script

  My scripts :

    "scripts": {
  
      "start": "react-scripts start",
  
      "build": "set \"FLUENTFFMPEG_COV=false\" && react-scripts build",
  
      "test": "react-scripts test",
  
      "eject": "react-scripts eject",
  
      "electron": "electron ."
  
    },

  Setting the env variable seems to not do anything, I still get the same error.
