-------------------------------------+-------------------------------------
We've a custom audio player built upon libav. We discovered that if we
compile libav on osx 10.10.3 without changing a single line of code, then
any AAC file decoding (see below) generates noise (you can't hear the
audio at all, just noise). However, if we compile ffmpeg on osx 10.9.5 and
we move the .dylib to 10.10.3, then AAC decoding works perfectly.
FFmpeg version: 2.8
(we also tested 2.3.6 and they issue is there too)
