Hi!
Mitch, Thanks for taking the time and do the test. This confirms the
problem is on my side.
And Carl Eugen, thanks for knowing what I'm talking about!
I installed ffmpeg one week ago on my mac via homebrew, using this command:

brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype
--with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis
--with-libvpx --with-opencore-amr --with-openjpeg --with-opus
--with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

So, in theory nothing would be disabled. Should I compile ffmpeg in some
other way?
Thank you
