[gst-devel] how to play h.264 file using gstreamer

[john david]

Hi,
             I tried to play h.264 ES using the below command,
*gst-launch-0.10 filesrc location=$1 ! ffdec_h264 ! ffmpegcolorspace !
deinterlace !xvimagesink*
but i'm not able to play the video and i got the *error messages like,*
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /pipeline0/ffdec_h2640: Internal GStreamer error:
negotiation problem.  Please file a bug at
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
Additional debug info:
gstffmpegdec.c(2317): gst_ffmpegdec_chain (): /pipeline0/ffdec_h2640:
ffdec_h264: input format was not set before data start
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
FREEING pipeline ...

What may be the reason.

Thanks and regards,
john david.
