ffmpeg | branch: master | Michael Niedermayer <michael at niedermayer.cc> | Tue Aug 18 03:27:52 2015 +0200| [628a73f8f3768513fa6152c98d54842cf2ae1aad] | committer: Michael Niedermayer

ffmpeg: force 128k default audio bitrate if nothing is specified and there is no specific default

This prevents breaking existing command lines in case the "ab" default is removed from libavcodec
