convert wmv to ogv

[Jerry Geis]

I am trying this pipeline to convert wmv to ogv.

gst-launch filesrc location=../trailer_videos/Amazon_1080.wmv !
                decodebin ! name=demux ! queue ! ffmpegcolorspace !
theoraenc !
                oggmux name=mux ! filesink location=../Amazon.ogv  demux. !
queue ! progressreport !
                audioconvert ! audioresample ! vorbisenc ! mux.

and getting this error:
0:00:00.025897773 25225      0x107d200 ERROR           GST_PIPELINE
./grammar.y:735:priv_gst_parse_yyparse: link without source element
0:00:00.025926967 25225      0x107d200 ERROR           GST_PIPELINE

./grammar.y:983:priv_gst_parse_launch: No element named "demux" - omitting
link
WARNING: erroneous pipeline: link without source element



I'm stuck... What do I have wrong.

Thanks,

jerry
