m4a issues

[Kyle]

Disregard my other post.. i had forgot to build the sample app with the
write defines for mp4

it appears on windows everything runs fine:

C:\Coding Projects\taglibtest\Debug>taglibtest.exe aac-test.m4a
******************** "aac-test.m4a" ********************
-- TAG --
title   - "Born This Way (Bimbo Jones Club Remix)"
artist  - "Lady GaGa"
album   - "Born This Way (The Remixes, Pt. 2)"
year    - "2011"
comment - "(Bimbo Jones Club Remix)"
track   - "5"
genre   - "Pop"
-- AUDIO --
bitrate     - 256
sample rate - 44100
channels    - 2
length      - 6:46

however my issue is on the android os.  I took the code from the sample and
put it into mine.. only changing the way of output (android log instead of
cout) and the result is all blacks

Using an mp4file instead of fileref i get this

Awhile ago I had some issues with some MP3 tags being cutoff at around 5-6
letters.. but I found someone else with that issue and used that code. thats
all that i did for modifications
modified code:

void String::prepare(Type t)
{
  switch(t) {
  case UTF16:
  {
    if(d->data.size() >= 1 && (d->data[0] == 0xfeff || d->data[0] ==
0xfffe)) {
      bool swap = d->data[0] != 0xfeff;
#ifndef __ANDROID__
      // ORIGINAL TAGLIB CODE.
      d->data.erase(d->data.begin(), d->data.begin() + 1);
#else
      // ERASE FUNCTION RESPONSIBLE FOR DUPLICATE CHARACTER ON SOME POSITION
OF STRING
      // CIRCUMVENTED BY THIS LOOP FOR NOW (bug reported to developer of
Crystax NDK R5)
      for(uint i = 0; i < d->data.size()-1; i++){
        d->data[i] = d->data[i+1];
      }
      d->data.resize(d->data.size()-1);
#endif

LOCAL_CFLAGS += -DTAGLIB_NO_CONFIG -DHAVE_ZLIB -DTAGLIB_WITH_MP4 -DWITH_MP4
-D__ANDROID__

could this be something similar?

Can you try the tagreader example application?
