No, they're distro provided (ubuntu).

Yes, quad core. No special options regarding threads. I'd expect vlc to do the right thing with multiple cores. Command I used was:

vlc --sout-mux-caching=1000 \
    --no-sout-transcode-hurry-up \
    --file-caching=1000 \
    --sout='#transcode{venc=x264,vb=800,fps=25,width=640,height=480,acodec=mp4a,ab=200,scale=1,samplerate=44100,channels=2,audio-sync,deinterlace}:standard{access=file,mux=ts,dst=/dev/null}' stream.dump > /dev/null 2>&1

It seems I have to investigate:
--sout-transcode-threads
--sout-transcode-high-priority
--sout-x264-mvrange-thread
--sout-x264-non-deterministic

Any other recommendations?
