[gst-devel] Internal GStreamer error: negotiation problem

[E.L.K.]

Hello, Gstreamer guys!

I'm expiriencing a problem, while trying to send data over unix
fd.

Easy way to reproduce it:
gst-launch-0.10 videotestsrc ! fdsink | gst-launch-0.10 fdsrc ! sdlvideosink

//============================================================

this gives output:
Setting pipeline to PAUSED ...
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
Pipeline is PREROLLING ...
ERROR: from element /pipeline0/sdlvideosink0: Internal GStreamer error: negotiation problem.  Please file a bug at http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
Additional debug info:
sdlvideosink.c(838): gst_sdlvideosink_show_frame (): /pipeline0/sdlvideosink0:
not negotiated.
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
FREEING pipeline ...

//============================================================

i've tried to do the same with xvimagesink with similar result:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...

//============================================================

I tried to insert filters between source and fdsink and fdsrc
and sink, this changes nothing.

Can you, please, say, where i'm wrong if so, or if this is really
a bug, give me any ideas, how to workaround it?
