AAC Conformance test 17 fails:

ftp://mpaudconf:adif2mp4ftp.iis.fhg.de/mpeg4audio-conformance/compressedMp4/a
l17_44.mp4
(as an example, all sample rates fail)

According to this email:
http://lists.mpegif.org/pipermail/mp4-tech/2003-
June/002397.html

"al17 tests the evaluation of the element_instance_tag
(it provides two SCEs,
     where the order of them switches from frame to
frame)"

When listening to the output, the L and R channels swap back
and forth.
