I tested it now with 

./configure --cc=clang --enable-shared
and with
./configure --cc=clang --disable-optimizations --disable-asm  --disable-yasm --enable-shared

Same result as before, no difference noticeable between the 2 variants, 
- with mp2 still a lot of errors, audio is garbled, and 
- with aac not so many errors, audio is ok most of the time, just a few errors every other second.

I had to include --enable-shared because otherwise the application would not link, reference errors to _kCVPixelBufferIOSurfacePropertiesKey and other stuff from libavcodec/vda.c.

The only console output are the errors, with mp2 a lot of the same missing header errors:

[mp2 @ 0x105002800] Header missing
[mp2 @ 0x105002800] Header missing
[mp2 @ 0x105002800] Header missing

[mp2 @ 0x105002800] Header missing
[mp2 @ 0x105002800] Header missing
[mp2 @ 0x105002800] Header missing

[mp2 @ 0x105002800] Header missing
[mp2 @ 0x105002800] Header missing
[mp2 @ 0x105002800] Header missing
… and so on and on, about 50% of all audio frames are concerned.

With aac :

[aac @ 0x1051b3c00] Error decoding AAC frame header.
[aac @ 0x1051b3c00] channel element 0.0 is not allocated
-after 1-5 seconds it continues-

- and so on.

There is no other console output.
