Comment (by d4eva):

 About version 2.8: I cloned source as "git clone
 http://source.ffmpeg.org/git/ffmpeg.git ffmpeg" and that's the version I
 got. I'm building on Windows using msys and mingw.

 --extra-cflags=-USTRICT_ANSI - some time ago I had some weird issues while
 building and then I added it (found the solution in google). Now I removed
 it and it worked just fine.

 About artifacts: -aac_tns 0 helped. Those artifacts sound much like very
 first mp3 encoders bac in the days. I tested with foobar, windows media
 player and ituenes and all of them sounded the same.

 Thanks for the lengths explanation.
