[GoogleCodeExporter]

What steps will reproduce the problem?
1. Playback mp4 media files with AAC audio from network share or USB stick .
2. No audio is played back . Video is fine.
3.

What is the expected output? What do you see instead?

AAC audio should play back .

What version of the product are you using? On what operating system?

OpenAR-P_OE2.0_211_alien_epl3-git-20-01-14_v2013-03-31-540-gb01d455.zip 

On Alien 1 Box (sti7111) .

Please provide any additional information below.

I simply installed 
OpenAR-P_OE2.0_211_alien_epl3-git-20-01-14_v2013-03-31-540-gb01d455.zip , 
didn't do anything but setup ethernet. Plugged in a USB stick with an mp4 video 
file with aac audio. The video is good, but no sound is heard.

Just to add - this worked just fine with the Jan 2013 ARP release :

OpenAR-P_OE2.0_211_alien_epl3-git-03-01-13_a65db78

Doesn't appear to be an audio.elf issue as the same file is used in the latest 
release (i checked md5sum between both releases) .

I don't know enough to track down what other modules / drivers deal with the 
decoding of AAC .

Seems like the following diff would fix it :

=====================================================

--- a/tdt/cvs/apps/misc/tools/libeplayer3/container/container_ffmpeg.c
+++ b/tdt/cvs/apps/misc/tools/libeplayer3/container/container_ffmpeg.c

223         case CODEC_ID_AAC:
224 -        return "A_AAC";
224 +        return "A_IPCM";

=====================================================

if someone could compile me a new libeplayer3 I could test the above if you 
like for sti7111 .

Some more info......

If I use the non-dts audio.elf, mp4 & aac audio works fine. 

However, in the 20th January 2014 build, mp4 & aac audio is out of sync. I just 
rebuilt using the latest git source, and it is now working fine again with the 
non-dts audio.elf .
