To get the same error with `fdkaac`:
{{{
$ ffmpeg -loglevel quiet -f lavfi -i sine=d=1 -f wav - | ./fdkaac - -b64
-p39 -f 2 -o out.aac
ERROR: encoder initialization failed

Works fine here for an actual encode:

I wonder what your original command line is supposed to do, it succeeds if
global headers are requested:

[http://ffmpeg.org/ffmpeg-codecs.html#libfdk_005faac Docs] show `aac_eld`

Linked to libfdk-aac 0.1.5.
Seems to work when using `fdkaac`:
{{{
$ ffmpeg -loglevel quiet -f lavfi -i sine=d=1 -f wav - | fdkaac - -b64
-p39 -o out.m4a

44100 samples processed in 00:00.012
}}}
Perhaps a problem on our end, but I didn't investigate and didn't try a
bisect.
