• Remove QTKit dependency

  30 October 2014, by Martin Delille

  I want to submint an application using FFMPEG to the Mac App Store but I get rejected because libavcodec links against the deprecated QTKit framework:

  Deprecated API Usage - Apple no longer accepts submissions of apps that use QuickTime APIs.

  I installed ffmpeg using brew install ffmpeg. How can I remove this dependency?

  FFMPEG issue that I am not familiar with. seems to only happen with this particular file. Anyone by any chance can take a look at this long out put and provide any feedback on what might actually be causing this?
