Am trying to encode a movie so that I can burn it onto a DVD.  Here is the
pipeline that I am trying to set up:

gst-launch --gst-debug-no-color --gst-debug-level=0 mplex name=mux format=8 !
filesink location=alias0404.mpg { filesrc location=alias0404.avi ! avidemux
name=demux { demux.video_00 ! queue ! ffdec_mpeg4 ! ffmpegcolorspace ! videobox
top=-32 bottom=-32 ! videoscale ! video/x-raw-yuv,width=720,height=480 !
mpeg2enc format=8 sequence-header-every-gop=true bitrate=10240 ! queue ! mux. }
{ demux.audio_00 ! queue ! mad ! ffenc_ac3 ! queue ! audio/x-ac3 ! mux. } }

RUNNING pipeline ...
