Reporter: edman007 | Type: defect

Summary of the bug:
I'm trying to convert mp4 files ripped from yourtube to aac audio (along
with one .aac file, it's trimmed audio from a youtube video). So i concat
the videos together and transcode to aac and ffmpeg crashed, playing
around with it I also got errors about unsupported features
I'm running git ffmpeg as of a few hours ago
How to reproduce:
{{{
% ffmpeg -y -f concat -i segfault.list -threads 12 -c:a aac -b:a 128k
-strict -2 out-segfault.aac
% ffmpeg -y -f concat -i scramble.list -threads 12 -c:a aac -b:a 128k
-strict -2 out-scramble.aac
}}}
-OR-
{{{
% tar -xvf ffmpeg-aac-bug.tar.xz ; cd bug-test
% ./execute.sh
}}}
First list of videos cause a segfault, second causes this error
