 Summary of the bug:
 How to reproduce:
 {{{
 % ffplay aac-denbosch.aac
 ffmpeg version 4.1.3 Copyright (c) 2000-2019 the FFmpeg developers
 built with Apple LLVM version 10.0.1 (clang-1001.0.46.3)
 }}}

 Leave it play for a while (about 25 seconds) and it will fail to
 successfully play further, even though the file contains more data. Thats
 because a de-sync happens and ffmpeg does not properly syncs again on a
 syncword, so it get garbage data for ADTS headers.
