Remove QTKit dependency
30 octobre 2014, par Martin DelilleI 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 ? -
