Bug#434369: vlc: segfaults when transcoding/streaming to ogg(theora+vorbis)

[Julien BLACHE]

Package: vlc
Version: 0.8.6-svn20061012.debian-5etch1
Severity: important

Hi,

vlc consistently segfaults when trying to transcode/stream from a v4l device
to an ogg(theora+vorbis) http (or whatever) stream.

Device:
v4l:// :v4l-vdev="/dev/video0" :v4l-adev="/dev/dsp" :v4l-norm=0 :v4l-frequency=-1 :v4l-caching=300 :v4l-chroma="" :v4l-fps=-1.000000 :v4l-samplerate=44100 :v4l-channel=1 :v4l-tuner=-1 :v4l-audio=-1 :no-v4l-stereo :v4l-width=0 :v4l-height=0 :v4l-brightness=-1 :v4l-colour=-1 :v4l-hue=-1 :v4l-contrast=-1 :no-v4l-mjpeg :v4l-decimation=1 :v4l-quality=100

Transcoding:
:sout=#transcode{vcodec=theo,vb=384,scale=1,acodec=vorb,ab=96,channels=1}:duplicate{dst=std{access=http,mux=ogg,dst=10.0.3.97:8000}}


Output:
% vlc

It looks a lot like an ancient vlc bug (Trac ticket #486).

The same bug exists in unstable, tested on both i386 and amd64.
