Use mpegtsdemux and not ffdemux_mpegts. The rule of thumb is : don't use
the ffmpeg demuxers (they have a rank of NONE for a reason).

Hi, Edward. Thanks for your answer. But, I could not install the mpegtsdemux. I saw that gstreamer-plugins-bad contains it but when I use "sudo apt-get install gstreamer0.10-plugins-bad" and nothing (I am using Ubuntu 8.10)... the packet "bad" is already the newer here in my OS. Can you tell me how I install this plugin?
 

And, Sean (below), the problem is not with osssink. I tried to run with the alsasink too, but it did not work. The error is:

 gst-launch-0.10 filesrc location="GLOBO188bytes.mpg" ! ffdemux_mpegts name=d d. queue ! ffdec_h264 ! xvimagesink d. queue ! faad ! audioconvert ! alsasink

Leaving the connection as PAUSED ...
The connection is making PREROLL ...
ERROR: of the element /GstPipeline:pipeline0/ffdemux_mpegts:d: Internal data stream error.
Aditional debbuging Information:

ERROR: the connection does not want to make preroll.
Leaving the connection in NULL ...
FREEING the connection ...

Thanks in advance!

Are you sure the problem isn't with osssink? Post the entire output of
using gst-launch with this command, and you may also try autoaudiosink
instead of osssink. If you're sure the problem isn't with the
audiosink, I'll need to see the rest of the output to know what
exactly went wrong.

HTH,

Sean
