Sorry about a possible repost. Keep using the wrong email account.
Nico - Awesome work. Thank you very much. Almost all of my samples work
perfectly now. I'll grab a bunch of fresh tests tonight from the Auckland
DTT transmissions as all of the channels have now switched to AAC.
Couple of bits of feedback.
1. I needed the following additional patch for my compile to work
Index: libmpcodecs/ad_faad.c
=================================================================== ---
libmpcodecs/ad_faad.c (revision 25826)
+++ libmpcodecs/ad_faad.c (working copy)

#include <faad.h>
#else

+#include "libfaad2/bits.h"
#include "libfaad2/faad.h"
#endif
2. I had to use the following configure option
./configure --with-extraincdir=../libfaad2
There appeared to be an issue with some of the newer definitions in the
faad2 headers.
I do have one sample that produces a couple of interesting debug message,
but it might be an issue with the broadcaster which is why I want to grab
some fresh samples
