The following pipeline produces a perfectly synced video when played by totem,
vlc etc.. Playing the same file in quicktime (7.6.4) produces slightly delayed
video.

gst-launch -e v4l2src ! 'video/x-raw-yuv,width=320,height=240,framerate=30/1' !
videorate ! ffmpegcolorspace ! ffenc_mpeg4 flags=0x00400000 ! queue ! mux.
alsasrc device=hw:0 ! audiorate ! faac profile=2 ! mux. mp4mux name=mux !
