AAC decoding regression

[fltmesoftly]

Summary of the bug:
FFMPEG produces errors on the provided - partial - sample file and dies at the very end of the - full - file. If needed I can provide the full file.

Sample uploaded to FTP as:
aark15sd_9A62E2FA_partial.mp4

How to reproduce:

Is the problem - that FFmpeg "dies at they very end of the - full - file" - also reproducible with the file you uploaded? If not, please upload a file that allows to reproduce the problem.

Is the problem you see only reproducible with version 1.0 or also with current git head?

I've tried with the latest static build, same error:
 http://ffmpeg.gusari.org/static/64bit/ffmpeg.static.64bit.2012-11-14.tar.gz

Nah, the partial only throws some errors. So, here is the full file:

The sample triggers different problems afaict, at least some of them indicate bugs in the aac decoder, possibly related to ticket #1694.

The first decoding problem occurs after 30 seconds, output changes to right-channel-ony, this cannot be undone with seeking, but if seeking is used to skip the position at ~30:00, output stays stereo. This is reproducible with both ffmpeg and ffplay (and MPlayer).

out.wav starts as a stereo file, switches to right-channel-only after ten seconds.
The following command line produces a stereo file:

$ ffmpeg -ss 35 -i aark15sd_9A62E2FA.mp4 -t 20 out.wav

A not necessarily related problem is that when transcoding fails while writing a isom/mov file, the resulting file is unplayable because no moov atom is written on exit. This is not a regression afaik, and I don't know if / how this behaviour can be changed.

$ ffmpeg -ss 710 -i aark15sd_9A62E2FA.mp4 -vn -acodec mp2 out.mov

Audio decoding is impossible from ~12:00 on, encoding fails and out.mov is not a valid mov file.

This is a regression since a6f650 - related to ticket #513.
