Please test with -an and -vn. If only -an allows to reproduce the issue, please test with -vcodec mpeg4 -qscale 2.

| Version: | unspecified → git-master |
Workaround is to use the native encoder which has a better sound quality:
-strict -2 -acodec aac
Since the crash apparently happens in an external library and is not reproducible with all versions of libvo_aac (works fine here), I close this ticket as invalid. If you believe there is a bug in FFmpeg that can be fixed within FFmpeg, you would have to provide a backtrace etc. as explained on https://ffmpeg.org/bugreports.html

i use the ffmpeg downloaded from http://johnvansickle.com/ffmpeg/
the defautl audio encoder is libvo-aacenc,i think it should be a bug of libvo-aacenc
i will compile ffmpeg and test later

Thanks for you help. I will use -strict -2 -acodec aac which work well!
