Version details: 0.8.3
Distribution/Version: mandrake 2.6.9

i install gstreamer-0.8.8, gst-plugins-0.8.7, and gst-ffmpeg-0.8.3 with       
prefix=/usr/local (default)...        
       
after configure, make, make install for all three of these source package..       
i did a gst-register and gst-register-0.8, both commands reside       
on /usr/local/bin       
       
i use the following script:       
#! /bin/sh       
#  note: <demux> may be plugins mpegdemux or ffdemux_mpeg or dvddemux       
#  note: <videodecoder> may be plugins ffdec_mpegvideo or ffdec_mpeg2video for       
MPEG2       
#  note: <colorspace> may be plugins ffcolorspace or ffmpegcolorspace       
#-----------------------------------------------------------------------------------------------------       
gst-launch filesrc location="./raw.media/a.unknown" ! \       
          mpegdemux name=demux \       
          demux.video_00! { queue ! ffdec_mpegvideo ! ffcolorspace !       
ximagesink } \       
      demux.audio_00! { queue ! ffdec_mp3 ! osssink }       
       
where ./raw.media/a.unknown is a file (actually a sym link) to a mpeg video       
file.       
       
i call this script play.video... and did a ./play.video and i got the       
following:       
RUNNING pipeline ...

note: there is another bug missing on this printout... one of my fellow       
colleagues hack away on ./src/gst-ffmpeg-0.8.3/extf/fmpeg/gstffmpegenc.c  
 
note: i also uninstall gstreamer-0.8.5 that originally comes with the mandrake 
installation. 
 
i'm at a dead end since i don't see anyone with this problem doing a google 
search..  please help. my email is jimbloke at gmail.com 
thanks.
