Vlc 2.0.5 and ffmpeg 1.1.3 segfaults if using AAC (MP4A)

Question

vlc segfaults when using aac (mp4a) audio codec on transcode

no problems when using mpga (mp3) audio. And problem starts after ffmpeg 1.0.1 -> 1.1.3

Answer 1

asus0 is symlink to vlc
asus0 -Idummy \
'v4l2:///dev/video0:input=1:standard=2:chroma=I420:width=720:height=576' ':input-slave=alsa://' \
--v4l2-aspect-ratio=16:9 \
--sout \
'#transcode{vcodec=h264{keyint=30},vb=512,fps=25,acodec=mp4a,ab=128,channels=2,fps=25,vt=1024000,deinterlace,canvas-aspect=16:9,aspect=16:9,samplerate=44100,hurry-up,high-priority}:duplicate{dst=std{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=:8080},dst=std{access=livehttp{seglen=10,delsegs=true,numsegs=5,index="/home/vlc/streaming/asus0.m3u8",index-url="http://leelo.folk.ee/streaming/asus0-########.ts"},mux=ts{use-key-frames},dst="/home/vlc/streaming/asus0-########.ts"},dst=std{access=http{mime=video/x-mpeg},mux=ts,dst=:8090},dst=rtp{sdp=rtsp://:8880/asus0.sdp},dst=std{access=file,mux=ts,dst="/home/vlc/save/FILE"}}' \
--ttl 12 --sout-ffmpeg-strict=-2 --rtsp-host=193.40.120.236
and big -vvv output from vlc is available http://www2.folk.ee/~jaanus/log.txt
valgrind output http://www2.folk.ee/~jaanus/valgrind.txt
strace -ff output http://www2.folk.ee/~jaanus/strace.txt
vlc, x264 & ffmpeg downgrade helps, but this information may be useful.
This issue is repeatable on different machines. No problem with mp3 audio, crash only occures when using AAC audio codec.
