[mythtv] MythMusic follow-up

[Mark Setzer]

More info:

This seems to be happening in MetaIOMP4::read  when, while scanning for  
new music (actually, while doing the db update), it tries to figure out  
the length of the track inside the mp4 file. The line:

if ( (track_num = getAACTrack(mp4_ifile)) < 0)

breaks with the missing symbols message found below.

Can anyone shed some light on why this might be happening? It's worth  
mentioning that mythmusic is indeed able to read all of the metadata  
associated with my test track (title, album, artist name, genre, etc).

Backtrace:
#0  MetaIOMP4::read (this=0x823cd78, filename=
       {static null = {static null = <same as static member of an  
already seen type>, d = 0x8175070, static shared_null = 0x8175070}, d =  
0x8ab5dc0, static shared_null = 0x8175070}) at metaiomp4.cpp:290

#4  0xb45889e1 in MusicCallback (data=0xbfffecf0, selection=@0x820dee8)
     at main.cpp:311

I assume the next step is to rebuild FAAD with debugging symbols and  
try to step into those functions as well, correct?
