New submission from zeta <***@magicinternet.de>:

I'm trying to encode a .mov into .flv but I get a message: [aac @
0x806d5d0] channel element 1.0 is not allocated. But in that file is
audio.
The resulting video has a size of 0 bytes.
I'm running: LD_LIBRARY_PATH=/data/tmp/00ffmpeg-test/ffmpeg-8ed4cc6/
install/lib/ ./ffmpeg -threads 4 -y -v 3 -i /data/tmp/00ffmpeg-test/
Reflection.mov -analyzeduration 25M -acodec libfaac -ab 96k -vcodec
libx264 -vpre fast -crf 22 -b 800k -s 640x480 -r 25.00 /data/
tmp/00ffmpeg-test/01testGR.flv 2>&1 | tee /data/tmp/00ffmpeg-
test/01LogfileGR.txt

The version of ffmpeg is one of the latest from the git. I think from
tuesday afternoon. And I try it as test version ;-)
The problem was first detected in the version:
FFmpeg version SVN-r25526, Copyright (c) 2000-2010 the FFmpeg developers
built on Oct 25 2010 17:38:44 with gcc 4.3.2

Today I uploaded (how it is descripted on:
http://www.ffmpeg.org/bugreports.html) a sample of one of these files which
makes problems.
The sample name is: 0_channels_and_channel_element_1.0_is_not_allocated.mov

It is a short scene of a promotion video.

confirmed that the behavior is the same with current libav git.
unless this is a regression, it is just a normal bug, not critical.
