mythtv missing aac support

Can mythtv be rebuilt with AAC support? I'm getting videos with no sound and
the following error:

2008-10-30 22:23:59.706 AFD: Opened codec 0xb11cbf0, id(H264) type(Video)
2008-10-30 22:23:59.706 AFD: codec AAC has 2 channels
2008-10-30 22:23:59.706 AFD Error: Could not find decoder for codec (AAC), ignoring.

I believe it just needs a buildreq for libfaad.

the BR is already in there, so are the --enable switches and the build
logs shows that all bits have been built with -lfaad. I can't say what
may be wrong, but a wil guess would be that you are perhaps using some
non-atrpms libs that do not support AAC?

Do I need anything other than the faad2 package?

'yum list \*faad\*' just shows faad2 and faad2-devel.

$ rpm -q --qf '%{PACKAGER}\n' faad2-2.6.1-8.fc9.i386

I think ffmpeg & x264 are relevant.

are you using a 64 bits machine?

I remember reading about how libfaad and libdts are broken on AMD64 platform...

I get the same error on a Mythbuntu install ; and it's definitely
built against libfaad

The hardware is 64bit capable Intel, but using a 32bit OS (trying to avoid just
these kinds of problems).

Should the binaries be linked to libfaad?

ldd on /usr/bin/mythfrontend and /usr/lib/mythtv/plugins/libmythvideo.so don't
show libfaad.

AFAIK mythvideo doesn't access faad directly, but through libavcodec.

Just as a test I grepped through mythvideo's sources and neither aac
nor aad come up (actually they do in the form of "IsAAC" or some
not relevant Estonian/Netherland translation)
